Fast Install Self-Supervising Fire Communicator
A fire alarm communication device having a first and second output voltage which are constant during normal operation of the fire communicator. During a trouble condition of the fire communicator, one of the output voltages is manipulated
1 . A fire alarm communication device comprising:
a first and second output voltage;
said first and second output voltage are constant during normal operation of the fire communicator; and
one of said first or second voltages is manipulated during a system trouble condition of the fire communicator.
2 . The fire communicator of claim 1 where said manipulation lowers one of the voltages.
3 . The fire communicator of claim 1 where said manipulation eliminates one of the voltages.
4 . The fire communicator of claim 1 where said system trouble condition is the failure of the fire communicator to check-in in a prescribed time period.
5 . The fire communicator of claim 1 where said system trouble condition is an inability of the fire communicator to establish communication with a cellular tower.
6 . The fire communicator of claim 1 where said system trouble condition is inability of the fire communicator to report to a central station.
7 . The fire communicator of claim 1 where said system trouble condition is when the voltage of the communicator is below a predetermined level.
8 . The fire communicator of claim 1 further including a battery and said trouble condition is when the voltage of said battery is below a predetermined level.
9 . The fire communicator of claim 1 wherein the communicator is a radio.
10 . The fire communicator of claim 1 wherein said constant voltage is around 48 volts DC.
11 . The fire communicator of claim 1 wherein said constant voltage is below 48 volts DC.
12 . The fire communicator of claim 1 wherein said first and second voltages are eliminated.
13 . The fire communicator of claim 1 further comprising a microprocessor and voltage control circuit.
14 . The microprocessor and voltage control circuit of claim 13 are further configured to lower the voltage to one or more outputs.
15 . The microprocessor and voltage control circuit of claim 13 are further configured to cease supplying a voltage to one or more outputs.
16 . The fire communicator of claim 13 further comprising at least one switch, said switch is closed during normal operation of the fire communicator and open during a trouble condition of the fire communicator.
17 . The fire communicator of claim 1 where said system trouble condition is an inability of the fire communicator to establish communication with a network.
18 . The fire communicator of claim 1 where said system trouble condition is a condition that inhibits the communication between the fire communicator and a central monitoring station.
19 . A fire alarm radio comprising:
a first and second output voltage;
said first and second output voltage are constant during normal operation of the fire radio; and
one of said first or second voltages is manipulated during a system trouble condition of the fire radio.
20 . The fire radio of claim 19 where said manipulation eliminates one of the voltages.
21 . The fire radio of claim 19 where said trouble condition is when the voltage of the radio is below a predetermined level.
22 . The fire radio of claim 19 further comprising a battery and said system trouble condition is when the voltage of said battery is below a predetermined level.
23 . The fire radio of claim 19 further comprising at least one switch, said switch is closed during normal operation of the fire communicator and open during a system trouble condition of the fire communicator.
24 . A method of connecting a fire alarm radio to a fire alarm control panel fire alarm control panel wherein the fire alarm control panel detects a fault condition by monitoring for a constant voltage from telephone line inputs comprising the steps of:
connecting a firm alarm radio to the fire alarm control panel by the telephone inputs; said fire alarm radio outputs a constant voltage to the telephone line inputs of the fire alarm control panel during normal operation of the fire radio; and
eliminating the voltage outputted to at least one telephone line input during a trouble condition of the fire radio.
25 . The method of claim 24 wherein said trouble condition is when the voltage of the radio is below a predetermined level.
26 . The method of claim 20 further comprising a battery and said trouble condition is when the voltage of said battery is below a predetermined level.
