PERFORMANCE REQUIREMENTS

4-1 Initiating Devices
4-1.1 Each initiating device shall be UL listed and powered by an internal battery(s) as specified to provide one year minimum operation.
4-1.2 Each initiating device shall transmit two levels of alarm status. Upon activation, the device shall transmit a signal indicating a initial alarm. Every sixty (60) seconds, while the device remains in alarm, a continuous signal shall be transmitted indicating continued alarm and this will continue until the device is automatically or manually restored.
4-1.3 Each initiating device shall transmit a test signal evidencing its ability to communicate and verify that its signal strength is within the acceptable tolerance levels prescribed by the manufacturer to provide adequate transmission. Failure of the control unit to receive the test signal within 200 seconds will result in a trouble indication at the control unit.
4-1.4 The internal power source of each initiating device shall be supervised and transmit a separate and distinct low battery signal when the battery voltage reaches the determined threshold set forth by UL. The initiating device shall be capable of full operation for a minimum of seven days after the initial low battery signal has been received at the control unit. This condition will report within 200 seconds.
4-1.5 The removal of an initiating device from its mounting shall result in a separate and distinct tamper signal which shall be transmitted within 200 seconds and displayed at the control unit.
4-1.6 When utilizing a wired fire transmitter, the wiring shall be supervised and any loss of wiring integrity shall be reported within 200 seconds at the control unit.
