44  Vigilant VS1 and VS2 Technical Reference Manual 
Table 13: Monitor device types 
Device type  Description 
Monitor  Monitoring of normally open switches for other functions (fire door 
position, etc.). Not approved for use under ULC 527 in Canada. 
Table 14: Output device types 
Device type  Description 
Continuous nonsilenceable  For nonsilenceable strobes and notification appliances that self-generate
a temporal pattern 
Continuous nonsilenceable 
(latched) 
For latching strobes and notification appliances that self-generate a 
temporal pattern 
Duct alarm  For duct smoke detectors. All activations are immediately considered as 
alarms. Circuit cannot be restored until devices are restored to normal 
and the panel is reset. 
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. 
Continuous silenceable  For strobes and notification appliances that self generate a noncoded 
tone 
Genesis audible visible 
silence 
For Genesis and Enhanced Integrity horns and strobes. Genesis and 
Enhanced Integrity appliances maintain synchronization per UL 1971. For
Genesis devices only, connected horns can be silenced and strobes turn 
off. 
Genesis nonsilenceable  For Genesis and Enhanced Integrity horns and strobes. Genesis and 
Enhanced Integrity appliances maintain synchronization per UL 1971. For
Genesis devices only, connected horns cannot be silenced and strobes 
on the same two-wire circuit flash until the panel is reset. 
Monitor  Monitor: Monitoring of normally open switches for other functions (fire 
door position, etc.). Not approved for use under ULC 527 in Canada. 
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.
