Indicators, Controls and Operations
9.3.2 Common Supervisory Relay
The Common Supervisory Relay (labeled SUPERVISORY RELAY on the circuit board)
activates when the common supervisory sequence is activated as the result of an alarm or any
un-bypassed latching or non-latching supervisory circuit. The relay is turned off if all non-
latching supervisory circuits are restored and there are no latching supervisory circuits active.
The relay can be disconnected by “Aux Disconnect” (see "Aux. Disc. (Command Menu)" on
page 75) if programmed to do so (see "Table 7 Feature Config menu" on page 56). This
Common Supervisory Relay will function the same way as a Common Alarm Relay if
programmed to (see "12 Common Supervisory Relay" on page 57).
9.3.3 Common Trouble Relay
The Common Trouble Relay (labeled TROUBLE RELAY on the circuit board) is activated
when the common trouble sequence is activated as the result of the trouble condition being
detected on the system. It is turned off when all troubles are cleared.
9.3.4 Auxiliary Alarm Relay
The Auxiliary Alarm Relay (labeled AUX. RELAY on the circuit board) functions the same way
as the Common Alarm Relay in every respect except that it can be disconnected by “Aux
Disconnect” (see "11.16 Aux. Disc. (Command Menu)" on page 75) with or without correlated
relays if it is programmed to do so (see "Table 7 Feature Config menu" on page 56). When
configured, the relay can also be disconnected if signal silence is active and reconnected if
signal silence is de-activated.
9.4 Circuit Types
9.4.1 Initiating (Detection) Circuit Types
9.4.2 Non-Verified Alarm
A non-verified alarm can have pull stations, smoke detectors, or heat detectors attached to it.
Activation of any of these devices will immediately result in an alarm condition in the Fire
Alarm Control Panel. An alarm condition causes the Common Alarm LED to illuminate red.
9.4.3 Verified Alarm
Verified alarms are verified by a reset and timing procedure, and may include smoke
detectors, heat detectors or pull stations. Activation of pull stations or heat detectors results in
an alarm condition in the Fire Alarm Control Panel within four seconds. Smoke detectors are
verified for a real alarm within 60 seconds, depending upon the startup time of the devices
Note: Some troubles are latching: once they are detected they remain active until
system reset. In this case the Common Trouble LED will also remain active until
system reset. The common trouble is not bypassed by the Auxiliary Disconnect
function.
Note: Each relay has an LED beside it. These LEDs are used for diagnostic purposes.
