•
Alarm LED (red) turns on steady when an alarm is detected
•
Supervisory LED (amber)turns on steady when the circuit is active
•
Trouble LED (amber)turns on at slow flash rate when in trouble or bypassed

turns on at slow flash rate when in trouble
8.3.5
Input Circuits Bypass Switch
These bypass switches are used to bypass the input circuit. Bypass is a toggle switch which
will bypass and un-bypass in a sequence whenever the switch is pressed. When the input
circuit is bypassed a trouble is generated and the system will not respond to any trouble or
alarm on the bypassed input circuit. If the bypassed input circuit is active and the Bypass
Switch is pressed for un-bypassing, the Alarm LED will flash at the fast rate for 10 seconds.
During these 10 seconds, pressing the Bypass Switch can bypass the active input circuit
again. After 10 seconds, the bypassed alarm will be processed.
8.3.6
Output Circuits Bypass Switch
The output circuit bypass switches bypasses the NAC circuit and the releasing circuit. The
switch is a toggle switch and pressing it again, will un-bypasses the output circuit the trouble
LED turns off.
