Vigilant VS1 and VS2 Technical Reference Manual 45
Device type Description
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.
Supervised output For modules that output an unsynchronized signal and that do not turn
off when you press Signal Silence.
Supervised output (latched) For latched output modules that output an unsynchronized signal and
that do not turn off when you press Signal Silence.
Unlatch outputs For output modules that are configured to manually unlatch latched
outputs [1]
[1] The following output modules can be configured to unlatch latched outputs: SIGA-CT1, SIGA-CT2,
SIGA-MAB, SIGA-MCT2, SIGA-MM1, and SIGA-UM.
