Chapter 2: Front panel programming
70 Vigilant VS1 and VS2 Technical Reference Manual
Device option Description
Photo detectors
Smoke: For smoke detectors and contact devices. All activations are immediately
considered as alarms. Circuit cannot be restored until devices are restored to
normal and the panel is reset.
Smoke verified: For smoke detectors and contact devices. Two-wire smoke
detector activations are verified (delayed and confirmed) before activating an
alarm. Four-wire smoke detectors and contact devices are not verified and
immediately considered as alarms. Circuit cannot be restored until devices are
restored to normal and the panel is reset.
Supervisory latching: For detectors that trigger an active (supervisory) event.
Detectors with this device type remain active until the condition that activated
them is restored and the control panel is reset.
Supervisory nonlatching: For detectors that trigger an active (supervisory) event.
Detectors with this device type remain active until the condition that activated
them is restored. Resetting the control panel is not required.
Ion detectors
Smoke: For smoke detectors and contact devices. All activations are immediately
considered as alarms. Circuit cannot be restored until devices are restored to
normal and the panel is reset.
Smoke verified: For smoke detectors and contact devices. Two-wire smoke
detector activations are verified (delayed and confirmed) before activating an
alarm. Four-wire smoke detectors and contact devices are not verified and
immediately considered as alarms. Circuit cannot be restored until devices are
restored to normal and the panel is reset.
Supervisory latching: For detectors that triggerman active (supervisory) event.
Detectors with this device type remain active until the condition that activated
them is restored and the control panel is reset.
Supervisory nonlatching: For detectors that triggerman active (supervisory)
event. Detectors with this device type remain active until the condition that
activated them is restored. Resetting the control panel is not required.
Duct detectors
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.
