5.0 Circuit (Zone) Disconnect Buttons
Circuit (zone) disconnect buttons are provided for all initiating and indicating circuits on the fire
alarm control panel. These buttons are located beside their respective indicating LEDs.
Pressing a circuit disconnect button disconnects that circuit from the system and turns on its
trouble indicator. While a circuit is disconnected, the panel will ignore all changes in the status
(alarms and troubles) of that circuit. Circuit disconnect buttons are toggle switches; therefore,
pressing an activated button a second time will reconnect the circuit.
Disconnecting an active latching initiating circuit such as alarms, water-flow alarm, sprinkler
alarm, general alarm, and latching supervisory does not affect its status until the panel is reset.
Disconnecting active non-latching initiating circuits including non-latching supervisory and
trouble-only causes them to behave as if the alarm situation has disappeared. Disconnecting
an active indicating circuit immediately deactivates the circuit.
When an initiating circuit disconnect button is pressed a second time, the panel checks the
state of the circuit. If the circuit is active and will cause a false alarm, the Status LED flashes
for ten seconds at the fast flash rate (red for alarm or amber for supervisory) without
processing the input. If the circuit is not re-disconnected by then, it will be processed as a new
input.
