Device option Description
Relay device types
Relay nonsilence NC: For relay devices that open when activated and remain
open when you press Signal Silence.
Relay nonsilence NC (latched): For latching relay devices that open when
activated and remain open when you press Signal Silence.
Relay nonsilence NO: For relay devices that close when activated and remain
closed when you press Signal Silence.
Relay nonsilence NO (latched): For latching relay devices that close when
activated and remain closed when you press Signal Silence.
Relay nonsilenceable: For relay devices that do not follow signal silence
Relay nonsilenceable (latched): For relay devices that do not follow signal silence
and do not restore until manually unlatched
Relay silence: For relays that turn off when you press Signal Silence.
Relay silence NC: For relays that open when activated and close when you press
Signal Silence.
Relay silence NO: For relays that close when activated and open when you press
Signal Silence.
Relay silenceable: For relay devices that follow signal silence.
Relay silenceable: For relay devices that follow signal silence.
Supervisory device types
Duct supervisory (latching and nonlatching): For duct supervisory devices.
Momentary activation of normally open devices immediately places the panel in
a supervisory state and turns on supervisory LEDs and relays. Circuit cannot be
restored until devices are restored to normal and the panel is reset.
Supervisory latching: For supervisory devices. Momentary activation of normally
open devices immediately places the panel in a supervisory state and turns on
supervisory LEDs and relays. Circuit cannot be restored until devices are restored
to normal and the panel is reset.
Supervisory nonlatching: For supervisory devices. Momentary activation of
normally open devices immediately places the panel in a supervisory state and
turns on the supervisory LED and relay. Annunciation remains active until the
input restores. The panel does not have to be reset.
Trouble device types
Remote AC fail: For use with auxiliary power supplies to provide AC Fail indication
to the fire panel. The fire panel treats this activation as if the panel itself detected
an AC fail condition. Delays off-premises signaling for the selected time duration.
Monitor device types
Monitor: Monitoring of normally open switches for other functions (fire door
position, etc.). Not approved for use under ULC 527 in Canada.
