EMERGENCY COMMUNICATION SYSTEM AB

STRACT An emergency communication system that is capable of broadcasting a live message to a specific zone of a protected structure, recording the live transmission, and repeating the recorded message to the same protected zone. In certain embodiments configured to protect multiple zones, the system further permits broadcast of a second live message to another zone of the structure, recording the second live broadcast, and repeating the second recorded message in the same zone to which the message was broadcast live. The system includes hardware such as a processing element and speaker assemblies and a computer program for instructing the processing element to carry out the transmission, recording, and re-broadcasting of messages through the speaker assemblies. BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention is generally directed toward an emergency communication system that may be installed within a protected area of a protected premises, such as a multi-level building, a sprawling single level building, or multi-building campus. The emergency communication system permits system operators to broadcast live messages to individual zones within the protected area, record the live messages while they are being broadcast, and then automatically replay the recorded messages. Thus, the system eliminates the need for a system operator to continuously broadcast the same live message to particular zones of the protected area. [0003] 2. Description of the Prior Art [0004] It is very common for modern commercial or public buildings to possess some type of alarm system capable of notifying occupants of a potentially dangerous situation, such as a fire. In the past, such systems upon actuation emitted a siren, bell, or other type of alarm that alerted building occupants to evacuate the structure. Typically, actuation of the alarm indicated the presence of a fire in the building. However, the alarm could also be actuated for other reasons such as inclement weather, hazmat incidences, or earthquakes. In addition, actuation of the alarm system could be accidental, i.e., a false alarm. Thus, it was left up to the

building occupants to decipher the intended meaning for the signal. This Would often lead to the assumption that the alarm Was false and the occupants would not take the required precautionary action. [0005] Over time, emergency communication systems were developed to permit broadcast of voice messages across a public announcement system installed within the building. Some systems permitted emergency responders or building personnel to broadcast a live or a pre-recorded page explaining the nature of the emergency and provide instructions to the building occupants. The message could even be directed to particular portions of the structure affected by the emergency condition as opposed to the entire building. With respect to systems employing pre-recorded messages, a primary shortcoming was that only those emergency situations that were likely foreseeable could be planned for and an appropriate message designed. If a pre-recorded message option was not appropriate for a particular situation, an emergency responder would have to live broadcast the information that the building occupants needed to hear. Further, the live instructions broadcast by the responder may even countermand a pre-recorded message as the responding personnel assess and react to the actual and developing conditions in real time. In this regard, the live announcements are usually the most important and are given the highest priority in the configuration of the systems. [0006] Typically, upon initiation of a live page by the system operator using a paging microphone or firefighter’s telephone, the live audio message is immediately broadcast over the system speakers. Once the page is completed, the system returns to its normal, automatic operational state. Further, in most instances, a system operator is only able to make one live announcement at a time, and if the message or instructions are to be repeated, the operator must remain at the system console and repeat the message in real-time. This leaves the operator unable to assist those responding to the emergency situation. Thus, a need exists for an emergency communication system that permits the communication of real-time, and not pre-recorded, messages to building occupants without requiring that one or more of the emergency responders be tasked with constant relaying of the messages to affected areas of the building.

[0007] According to one embodiment of the present invention there is provided an emergency communication system capable of distributing audible messages to a protected area located within a protected premises having at least one protected zone. The system generally comprises a processing element, a memory unit, and a speaker assembly associated with the processing element. The speaker assembly comprises a speaker circuit and one or more speakers being located within the protected zone. The processing element is operable to transmit a live, spoken message through the speaker circuit to the protected zone speakers, store the message in the memory unit, and cause the message to be repeated as a repeated message through the speaker assembly speakers. [0008] According to another embodiment of the present invention there is provided an emergency communication system capable of distributing audible messages to a pro- tected area comprising at least two protected zones. The system comprises a processing element operable to transmit a first live, spoken message through a first speaker assembly comprising a first speaker circuit and one or more speakers located within a first protected zone. The processing element is further operable to transmit a second live, spoken message through a second speaker assembly comprising a second speaker circuit and one or more speakers located within a second protected zone. The processing element is further operable to store the first and second messages in a memory unit and to cause the first message to be repeated through the first speaker assembly speakers as a first repeated message and the second message to be repeated through the second speaker assembly speakers as a second repeated message. [0009] According to yet another embodiment of the present invention there is provided a non-transitory computer-readable storage medium with an executable program stored thereon for distributing audible messages to an area protected by an emergency communication system. The program instructs a processor to receive a live, spoken message, transmit the message through a speaker assembly comprising one or more speakers located in a protected zone within the protected area, and repeat the message as a recorded message through the protected zone speakers. Particularly, the program instructs the processor to record the message as it is being transmitted through the speaker assembly thereby enabling the repetition of the message subsequent to the initial live transmission. In another embodiment, the program also instructs the processor to receive a second live, spoken message, transmit the

second message through a second speaker assembly comprising one or more speakers located in a second protected zone within the protected area, and repeat the second message as a second recorded message through the second protected zone speakers. [0010] According to still another embodiment of the present invention there is provided a method for distributing audible messages to an area protected by an emergency communication system. The method comprises receiving a live,spoken message, transmitting the message through a speaker assembly comprising one or more speakers located in a protected zone within the protected area, and repeating the message as a recorded message through the protected zone speakers. In an additional embodiment, the method further comprises receiving a second live, spoken message, transmitting the second message through a second speaker assembly comprising one or more speakers located in a second protected zone within the protected area, and repeating the second message as a second recorded message through the second protected zone speakers. BRIEF DESCRIPTION OF THE DRAWINGS [0011] FIG. 1 is a schematic diagram of an emergency communication system in accordance with one embodiment of the present invention installed within a multi-level building; [0012] FIG. 2 is a schematic diagram of an emergency communication system in accordance with one embodiment of the present invention installed within a single protected space; [0013] FIG. 3 is a schematic diagram of an emergency communication system in accordance with one embodiment of the present invention installed within a single-level building having a plurality of discrete zones protected by the system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0014] As noted above, the present invention is generally directed toward an emergency communication system configured to be installed within a building or other protected areas and to deliver audible messages to one or more protected zones within the building or protected area. Turning to FIG. 1, a multi-level building 10 is illustrated comprising a plurality of floors 12, 14, 16, 18, and 20, at least a portion of each floor constitutes a protected zone. An emergency communication system 22 is shown installed within building 10.System 22 can take on any number of configurations as would be appropriate for a given structure, and such

4

兰州交通大学毕业设计(英文文献)
would be understood by one skilled in the art. Therefore, the embodiments illustrated in the Figures are exemplary and should not be taken as limiting the scope of the present invention. [0015] System 22 comprises a command center 24 which includes a console having some kind of user interface to enable an operator to control the system. Note, even though command center 24 is shown as being located in the building’ s first level, command center 24 may be located anywhere in building 10 or even in a remote or off-site location. The user interface may take the form of a panel having a plurality of buttons or switches and include a audio input, such as a microphone or other type of handset, operable to receive the operator’s voice input so that live messages may be broadcast through the system to all of or at least some portions of building 10. It is also within the scope of the present invention for the audio input to be located remote from command center 24, and even off site from building 10. [0016] Included within system 22, and in certain embodiments within command center 24, is a processing element that controls the operation of system 22. The processing element may be any device, or combination of devices, equipped with a processor capable of implementing operator systems or executing a computer program, which is also generally known as instructions, commands, software code, executables, applications, apps, and the like. The processing element may include processors, microprocessors, microcontrollers,

field-programmable gate arrays (FPGAs), or the like, as well as combinations thereof. [0017] System 22 further comprises a memory element that is capable of storing or retaining any computer program utilized to control the processing element as well as data that is received by system 22, such as text, databases, graphics, audio, video, and combinations thereof The memory element may also be known as a “computer-readable storage medium” and may include non-transitory components such as random access memory (RAM), read only memory (ROM), flash drive memory, hard disk drives, optical storage media such as compact discs (CDs or CDROMs), digital video disc (DVD), Blu-RayTM or the like, as well as combinations thereof As described in greater detail below, the memory element may be a single memory unit associated with the processing element, or may comprise a plurality of memory elements distributed throughout system 22. [0018] System 22 further comprises a plurality of speaker assemblies 26, 28, 30, 32 that are associated with, operably coupled to, or otherwise connected with the processing element. Each of the speaker assemblies comprise one or more speakers 34 installed within a particular
5

兰州交通大学毕业设计(英文文献)
floor or protected zone. Speakers 34 are interconnected with each other and associated with the processing element via a speaker circuit 36. In certain embodiments, the speaker circuits 36 are associated with the processing element via a communication path 38 that is dedicated for use only by said emergency communication system and is not shared by any other building systems. In particular embodiments, communication path 38 may be a wiring system, such as a dedicated two-wire system, or fiber optic cabling. However, in certain embodiments, it may be possible to utilize an internet protocol (IP) Ethernet or DSL communication systems as the communication path, even though such systems may not be dedicated for use only by the emergency communication system. Furthermore, even though communication path 38 is illustrated as a wired communication system, it is understood that communication path 38 may also comprise wireless technology, and that appropriate receiving and transmitting equipment be employed as a part of path 38. [0019] Further distinguishing emergency communication systems according to the present invention from other types of communication or paging systems is that emergency communication systems may also include a back-up power source to permit operation of the system even though the building’s main power source may be accidentally interrupted as a part of the emergency situation or intentionally interrupted in response to the emergency situation. In particular embodiments, this back-up power source should be capable of operating system 22 for at least 24 hours following disconnection of the building’ s primary AC power source. Emergency communication systems are generally supervised for system integrity from end to end so that any faults or malfunctions are immediately detected and can be rectified. Other paging systems for non-emergency use do not include this high level of supervision. Emergency communication systems are also constructed to permit operation of the system even through a ground fault. In certain embodiments, emergency communication systems have the capability of prioritizing the sending of signals through the system. For example, live messages are given priority over pre-recorded messages with respect of delivery to a particular protected zone. The use of dedicated signaling cables is important to this message prioritization aspect. Other communication systems which employ Ethernet technology do not prioritize the sending of signals through the system. Also, emergency communication systems can be integrated with a “failsafe” tone if cable or signal integrity is lost during an alarm event thus ensuring that the system will provide at least some type of
6

alert to the building occupants even though the system is damaged or its function ality diminished. With an Ethernet-based system, the system is generally disabled by a loss of cable or signal integrity. [0020] Speaker assemblies 26, 28, 30, and 32 may also comprise one or more amplifier units 40. The amplifier unit 40 for each respective speaker assembly may be located on the same floor as the speakers 36 for the respective speaker assembly, or the amplifier units may be housed in a common location such as the command center 24. In certain embodiments, however, it may be preferable for the amplifier units to be dispersed throughout building 10 as this may assist with the survivability of certain portions of system 22 should some other portions become damaged by an emergency situation, such as fire. As explained further below, the amplifier units 40 may be associated with memory elements comprising the aforementioned memory unit, so that messages intended for a particular zone or floor may be locally stored should other portions of system 22 become damaged and rendered nonfunctional. [0021] FIG. 2 illustrates an alternate embodiment according to the present invention in which a building 41 comprising a single protected zone. An emergency communication system 43 is installed within building 41. System 43 comprises a number of the same components and operational characteristics as system 22 described above. Namely a speaker assembly 26 comprising a plurality of speakers 34 is installed within the protected area within building 41. Speakers 34 are interconnected with each other and associated with a processing element located within a command center 24 via speaker circuit 36. Speaker circuit 36 may be associated with the processing element via a communication path 38 as previously described. System 43 is also shown as being equipped with an amplifier unit 40, although, it is within the scope of the present invention for amplifier unit 40 to be housed within command center 24. [0022] FIG. 3 illustrates an alternate embodiment of the present invention in which the communication system is installed within a building 42 having multiple protected zones on the same level. Although building 42 is illustrated as comprising a single level, it should be noted that the concepts of this embodiment are equally applicable for multi-level buildings such as building 10 of FIG. 1 having individual floors comprising multiple protected zones. [0023] Building 42 includes a plurality of protected zones 44, 46, 48, 50. A communication system 52, similar in configuration to communication system 22 of FIG. 1, is installed within

building 42. A command center 24 is shown installed within protected zone 44, although, it is within the scope of the present invention for command center to be situated in a different portion of building 42 or at a remote site. Command center 24 is shown associated with a plurality of speaker assemblies 54, 56, 58, 60 installed within a respective protected zone. In all other respects, the speaker assemblies of FIG. 3 are similar to those of FIG. 1 in that they each comprise one or more speakers 34 interconnected by a speaker circuit 36, and in certain embodiments an amplifier unit 40. Also, speaker circuits 36 are associated with a processing element, such as may be found in command center 24, by a dedicated communication path 38. [0024] As discussed further with respect to the operation of communication systems 22, 43, and 52, the systems are equipped with one or more audio input devices 62. Audio input devices 62 may comprise any type of communication source capable of receiving an audio signal including, but not limited to a fireman’s phone or other type of microphone. Typically, one audio input device 62 is associated with or in close proximity to the command center 24, although, it is within the scope of the present invention for additional input devices 62 to be located throughout buildings 10, 42 and in particular in each protected zone or floor. Further, each of input devices 62 remote from command center 24 may be associated with a secondary control panel (not illustrated) which may be of similar functionality as command center 24, but possibly more limited in terms of system-wide access. Additionally, systems 22, 43, and 52 may also include other peripheral apparatus installed within buildings 10, 42 such as pull stations, smoke detectors, heat detectors, gas detectors, video systems, emergency communication and notification devices. [0025] In the event of an emergency situation within the protected area, such as building 10, 41, or 42, the emergency communication system 22, 43, 52 is functional to permit responding personnel to deliver real-time customized messages to particular protected zones within the protected area, and then cause those messages to be automatically repeated in the particular zones to which they were originally delivered in real-time. This automatic recording of the live message as it is being delivered to the protected zone and its repetition permits the responder to speak the message a single time and then be able to assist with addressing the emergency situation, instead of having to repeat the message live. [0026] The operation of emergency communication systems according to the present invention will be described with particular reference to system 22 of FIG. 1. However, it is
8

noted that the operation of systems 43 and 52 are essentially similar, with exception that system 43 is configured to protect a single zone. Therefore, the following discussion should be viewed as being applicable for systems 43 and 52 and not limiting in any way on the scope of the present invention. An emergency situation, such as a fire, might initiate emergency communication system 22 to deliver a pre-recorded voice message to occupants within building 10, 42 alerting them to the situation. Upon arrival, responding personnel, such as firefighters, may determine that the pre-recorded message is not appropriate for certain portions of the building, or they may wish to deliver specific instructions to certain occupants of the building. For example, in the event of a fire on floor 20, the emergency responders may wish to advise occupants of floor 20 to exit the floor via a particular escape route. In order to accomplish the evacuation of floor 20 in the most expedient manner, the responders may want the occupants of floors 14 and 16 to remain in place so as to avoid overcrowding of the escape route or direct the occupants of those floors to evacuate through an alternate escape route. The functionality of system 22 permits the emergency responders to deliver a first, live message to the occupants of floor 20, and cause that same message to be repeated a plurality of times. Once the first live message has been delivered, the emergency responders may transmit a second live message to the occupants of floors 14 and 16 with an alternate set of instructions and cause that second message to be repeated a plurality of times. [0027] In order to accomplish this mission, the processing element utilized by system 22 must be operable to transmit a first live, spoken message through speaker assembly 32 located on floor 20, store that message within the memory unit, such as within a memory element comprising amplifier unit 40 associated with speaker assembly 32, and cause the message to be repeated through said speakers 34 of speaker assembly 32. The processing element must also be operable to transmit a second live, spoken message through speaker assembly 26, for example, located on floor 14, store that second message within the memory unit, such as within a memory element comprising amplifier unit 40 associated with speaker assembly 26, and cause the message to be repeated through speakers 34 of speaker assembly 26. [0028] In another aspect, the present invention is also directed toward a non-transitory computer-readable storage medium with an executable program stored thereon and method for distributing audible messages to an area protected by the emergency communication system 22. The computer program and the method may be implemented in hardware, software,

兰州交通大学毕业设计(英文文献)
firmware, or combinations thereof. In keeping with the above illustration, the computer program instructs the aforementioned processor to receive a first live, spoken message which may be delivered by an emergency responder via one of input devices 62, transmit the first message through speaker assembly 32 which includes one or more speakers 34 located on floor 20, and repeat the first message as a first recorded message through the same speakers 34. The computer program further instructs the processor to receive a second live, spoken message which may delivered by an emergency responder via the same input device 62 which delivered the first message or through a different input device located in building 10. The program instructs the processor to transmit the second message through speakers 34 of speaker assembly 26 located on floor 14, and then repeat the second message as a second recorded message through the speakers 34 of assembly 26. [0029] In certain embodiments, the computer program also instructs the processor to store the first message in a first memory element such as might be found in amplifier unit 40 that is associated with speaker assembly 32, and store the second message in a second memory element such as might be found in amplifier unit 40 that is associated with speaker assembly 26. As noted above, the first and second messages may comprise individualized instructions for the occupants of each floor. Further, the computer program may also instruct the processor to repeat each stored message a plurality of times, for instance until the emergency situation has been abated and the system operator cancels the messages. [0030] In certain embodiments, system 22 includes the functionality to permit any pre-recorded messages initiated by detection of the emergency condition to continue to repeat on floors where live, customized messages were not directed. Thus, system 22 permits the simultaneous broadcast of live, real-time messages, repeats of those live messages, and pre-recorded messages throughout various portions of building 10. Further, system 22 permits prioritization of messages so that live broadcast messages preempt pre-recorded messages. [0031] Although the operation of system 22 has been illustrated by the foregoing example, such example should not be viewed as limiting on the scope of the present invention. Further, it can be appreciated that system 43 illustrated in FIG. 2 and system 52 illustrated in FIG. 32, may be operated in a similar manner with the exception that the messages are delivered to the lone protected zone, as in system 43, or to individual protected zones 44, 46, 48, 50, instead of floors 12, 14, 16, 18, 20, as in system 52.

从而确保即使在系统损坏或它的功能减少的情况下,系统将提供至少一些类型的警报给 建筑物的居住者。与基于以太网的系统,该系统一般是通过电缆或信号完整性损失而被 禁用。 扬声器组件 26,28,30,和 32 也可以包括一个或多个放大器单元 40。对于每个相 应的扬声器组件放大器单元 40 可以和用于相应扬声器组件的扬声器 36 位于同一楼层, 或在放大器单元 40 可以被容纳在一个共同的位置,如在指挥中心 24。然而,在某些实 施方案,放大器单元分散贯穿在整个建筑 10 是更可取的,因为这可以协助系统 22 的某 些部分的生存能力在其他部分被损坏的紧急情况下,如火灾。下面进一步解释,放大器 单元 40 可与包含在上述提及的存储器单元的存储器元件相关联,以便用于一特定区域 或楼层的消息可以被存储在本地,该系统 22 的其它部分被损坏和呈现非功能。 图 2 示出根据在其中一个包括单个受保护的区域的建筑物 41 中的现有发明的替代 实施例。 应急通信系统 43 是安装在建筑物 41, 系统 43 包括多个相同的组件和操作特性, 如上所述系统 22。 即是扬声器组件 26 包括多个安装于建筑物 41 的保护区域内的扬声器 34。扬声器 34 彼此互连,并通过扬声器电路 36 和位于一个指挥中心 24 的处理元件相 关联。扬声器电路 36 通过如先前所描述的通信路径 38 和处理元件相关联。系统 43 也 被示为配备有一个放大器单元 40,尽管,这是现有发明的范围之内,放大器单元 40 被 容纳在指挥中心 24。 图 3 示出的是一个通信系统安装在具有同一水平上的多个保护区域的建筑物 42 内 的现有发明的替代实施例。尽管建筑物 42 被示为包括一个单一的水平,但应注意的是, 本实施例的概念也同样适用于多级的建筑物如图 1 的建筑物 10 的个别楼层包含许多的 保护区。 建筑物 42 包括多个受保护的区域 44,46,48,50,一种被安装在建筑物 42 内的通 信系统 52,在配置上和图 1 的通信系统 22 相似,指挥中心 24 被示安装在保护区 44.。 尽管,在现有发明的适用范围内,指挥中心可地处建筑物 42 的不同部分,或远程站点。 指挥中心 24 被示出与多个安装在单独保护区内的扬声器组件 54,56,58,60 相关联。 在所有其他方面,图 3 的扬声器组件类似于图 1,由于它们各自包括一个或多个由扬声 器电路 36 相互连接的扬声器 34,还有在某些实施方案中的放大器单元 40。同样,扬声 器电路 36 与处理元件相关联,例如可以在指挥中心 24 被发现,通过专用通信路径 38。 关于通信系统 22,43 和 52 的操作的进一步讨论, 这些系统配备了一个或多个音频输 入装置 62。音频输入装置 62 可以包括任何类型的通信源,能够接收包括但不限于消防 员的电话或其它类型的话筒的音频信号。特别地,一个音频输入装置 62 接近或和指挥

中心 24 相关联,虽然,在现有发明的范围内,额外的输入设备 62 可以位于整个建筑物 10,42 和特别是在每个受保护区或楼层上。另外,每个远离指挥中心 24 的输入设备 62 可能与一个在功能上和指挥中心 24 相似的二级控制面板(未示出)相连接,但就整个 系统的访问而言可能更有限。此外,系统 22,43 和 52 也包括安装在建筑物 10,42 内 其它外围设备,如拉站,烟雾探测器,感温探测器,燃气探测器,视频系统,应急通信 和通知设备。 万一在保护区范围内有紧急情况发生,如建筑物 10,41,或 42,应急通信系统 22, 43, 52 是功能允许响应人员提供实时定制消息到保护区域内特定的保护区, 然后使这些 消息在最初实时消息递达的特定区被自动地重复。当现场消息被发送到保护区时,它的 这种自动记录允许救援人员在一个时间内讲述消息,然后才能协助解决紧急情况,而不 必重复直播消息。 根据现有发明的应急通信系统的操作将用图 1 特别提及的系统 22 来描述。然而, 应当注意的是系统 43 和 52 中的操作基本上是相似的,除了系统 43 被配置为保护单一 区域。因此,下面的讨论应被看作是适用于系统 43 和 52,而不是以任何方式进行对现 有发明的范围进行限制。遇到紧急情况,如火灾,可能会启动应急通信系统 22 提供一 个预先录制的语音信息给建筑物 10,42 内的居住者使他们警戒紧急情况。抵达后,响应 人员,如消防员,可以确定预录制的消息是不适用于此建筑物的某些部分,或者他们可 能希望提供特定指令给此建筑物的居住者。例如,万一 20 楼着火,紧急救援人员可能 希望通知 20 楼的住户通过一个特定的脱险通道退出此楼层。为了以最便捷的方式完成 20 楼的疏散, 救援人员可能需要 14 层及 16 的居住者留在原地, 以免逃生路线拥挤或指 示这些楼层的居住者通过备用脱险通道疏散。系统 22 的功能性允许紧急响应者提供第 一现场消息给 20 楼的居住者,并使同样的消息被重复多次。一旦第一现场消息被传送, 紧急响应者可以使用备用的指令集发送第二现场消息到楼层 14 和 16 的居住者,并使第 二消息被重复多次。 为了完成这一任务,通过系统 22 使用的处理元件必须是用于发射的第一现场,语 音消息通过位于 20 楼的扬声器组件 32,使用存储单元存储信息,例如存储器元件,其 包括与扬声器组件 32 相关联的放大器单元 40, 并导致该消息通过扬声器组件 32 的扬声 器 34 被重复。处理元件也必须可操作的发射第二现场,语音消息通过扬声器组件 26, 例如,位于 14 楼,在存储单元内存储第二消息,例如存储器元件包括与扬声器组件 26 相关的放大器单元 40,并且使得该消息通过扬声器组件 26 的扬声器 34 被重复。 在另一个方面,现有发明还针对一种非临时性计算机可读的存储介质,具有一个存

储在其上的可执行程序和方法用于分配可听消息到应急通信系统 22 所保护区域。计算 机程序和方法可在硬件,软件,固件,或其组合上来实现。符合上述说明中,计算机程 序指示上述处理器接收第一现场和口语消息, 其可以由紧急响应者通过一个输入装置 62 中的一个被传递,并通过包含位于 20 楼的一个或多个扬声器 34 的扬声器组件 32 发射 第一消息,通过相同的扬声器 34 重复第一消息作为第一记录消息。计算机程序进一步 指示处理器接收第二现场和口语消息由紧急响应者通过相同的传递第一消息的输入装 置 62 或位于建筑物 10 的不同输入装置来传递,还有通过 14 楼扬声器组件 26 的扬声器 34 来发射第二消息, 然后通过扬声器组件 26 的扬声器 34 重复第二消息作为第二记录消 息。 在某些实施方案中,计算机程序还指示处理器在第一存储器元件中存储第一消息, 例如可能会在与扬声器组件 32 相关的放大器单元 40 中找到,并在第二存储元件中存储 第二消息,诸如可能会在与扬声器组件 26 相关的放大器单元 40 中找到。如上所述,第 一和第二消息可以包括用于每一层的居住者的个性指令。此外,该计算机程序也可以指 示处理器多次重复每个存储消息,例如,直到紧急情况已经被减弱系统操作员才取消的 消息。 在某些实施方案中, 系统 22 包括允许通过检测紧急情况发起任何预先记录的消息, 以继续重复未指示的有直播,定制消息的楼层的功能。因此,系统 22 允许同时广播实 况,实时消息,这些实况消息的重复,和预先录制的信息贯穿建筑物 10 的不同部分。 此外,系统 22 允许消息的优先化,使得现场广播消息优先于预录制消息。 尽管系统 22 的操作已经由上述实施例说明,例如实施例不应被看作是对现有发明 的范围的限制。此外,可以理解的是,图 2 的系统 43 和图 32 的系统 52,可能以同样的 方式被操作除了被传递到单独保护区的消息,如在系统 43 中,是到单独的保护区 44, 46,48,50 而不是系统 52 中的楼层 12,14,16, 18,20。
