Vigilant VS1 and VS2 Technical Reference Manual  71 
Device option  Description 
  Heat detectors 
Heat alarm: For heat 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. 
Heat alarm RoR: For heat detectors and contact devices with rate-of-rise. All 
activations are immediately considered as alarms. Circuit cannot be restored 
until devices are restored to normal and the panel is reset. 
  Input module device types 
2Wire Class A: Allows for the monitoring of two-wire conventional smoke 
detectors in a Class A circuit (that do not require alarm verification) and normally 
open contact initiating devices on the same circuit. 
2Wire Class B: Allows for the monitoring of two-wire conventional smoke 
detectors in a Class B circuit (that do not require alarm verification) and normally 
open contact initiating devices on the same circuit 
2Wire verify Class A: Allows for the monitoring of two-wire conventional smoke 
detectors in a Class A circuit (that require alarm verification) 
2Wire verify Class B: Allows for the monitoring of two-wire conventional smoke 
detectors in a Class B circuit (that require alarm verification) 
Alarm: 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. 
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. 
Heat: For heat 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. 
Pull station: For pull station devices. All activations are immediately considered 
as alarms. 
Remote drill: For a remote switch that when activated, starts the panel’s drill 
operation. 
Remote reset: For a remote switch that when activated, resets the panel. 
Remote signal silence: For a remote switch that when activated, silences the 
signaling devices. 
Waterflow: For connecting vane type and pressure flow switches. Activations are
considered as alarms. A 16-secondalarm delay applies to waterflow activations. 
Circuit cannot be restored until devices are restored to normal and the panel is 
reset. Waterflow activations do not invoke in-suite signal silence.
