Integrated alarm, security, building management, and communications system
First Claim
1. A building alarm, communication, and operating system, comprising:
- a centrally located control unit;
a plurality of sensing units each having an individual address and being located remotely from said centrally located control unit;
a plurality of operating devices each having an individual address and being located remotely from said centrally located control unit;
said control unit including a clock means producing a clock signal and a synch signal generating means for producing a synch signal from said clock signal;
a first conductor connecting said clock means to a plurality of convertor and decoder means remotely located with each of said plurality of sensing units and said plurality of operating devices for continuously feeding said clock signal thereto;
a second conductor connecting said synch signal generating means to each of said plurality of convertor and decoder means for feeding said synch signal thereto;
each of said plurality of convertor and decoder means containing an address unique to one of said sensing units and operating devices;
a third conductor connecting each of said plurality of sensing units to said control unit for feeding a monitoring signal from said sensing units to said control unit;
a plurality of loudspeakers being located remotely from and electrically connected to said centrally located control unit;
communication means connected to said plurality of loudspeakers and said control unit for permitting bidirectional communication between said plurality of loudspeakers and said centrally located control unit;
display means electrically connected to said centrally located control unit and connected to receive said monitoring signal from said plurality of sensing units for indicating whether any sensing device has sensed an emergency condition; and
command means connected to receive said clock signal for producing an actuation command signal fed on a fourth conductor to said plurality of remote operating devices for causing selected ones of said operating devices to perform a work function, whereby personnel at said centrally located control unit can communicate with remote locations and can be informed of various conditions detected by said sensing devices.

Abstract
A fully integrated alarm, communication, and building management system has a central control station and a plurality of remotely located sensing and controlling devices. Each remote device has an individual digital address, which is a parallel address present on a plurality of parallel lines. The parallel address is converted to a serial address and sent to the various remote locations where it is then reconverted to a parallel address and decoded to determine the specific device being interrogated. A multiple amplifier system is provided at the central control unit and provides communication capability involving remotely located loudspeakers and microphones. The amplifiers are provided in a dual channel arrangement so as to provide a fail-safe arrangement and a failure detector is located in each channel such that if a selected amplifier channel fails, the back-up or redundant channel is immediately switched into use. A number of controlling devices or actuating devices may be employed which operate in conjunction with the sensing devices and a programmable read only memory, or a programmable multiplexer, located at the central control unit. Each remotely located controlling or actuating device also has associated with it an individual parallel digital address and upon the occurrence of a signal from a sensing unit indicating a condition other than a normal condition and a specific address programmed into the programmable read only memory or the multiplexer a command signal will be issued to the remotely located actuating or controlling device causing such device to operate in a predetermined manner.
