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.
