Features of the Onguard 800 System Input Module

  • Three independent inputs applicable to any dry input contact device, such as optical, smoke, or heat detectors
  • Three independent input time delays adjustable from 0 to 15 seconds
  • Auxiliary form C fire relay can be independently voted
  • Relay is selective for latching or non-latching
  • Memory feature allows alarm LED to remain on during alarm and blinks when alarm clears
  • Input voting capability has independent control transferred to Alarm Module and Release Module
  • Recessed detector test switch option able to source or sink current
  • Detector fused power output and reset switch
  • All field wiring supervised per NFPA requirement

Onguard 800 System Input Module

The model 1440 Input Module is the initiating module which connects up to three independent dry relay contacts from detector outputs. Adding additional modules expands the number of points of fire detection in three point increments. The three discrete inputs can be voted between each other adding confidence to the system. Output relay is individually controlled from the DIP switch configuration. The Alarm, Release and Relay Modules are activated in a pre-selected sequence established from the DIP switch configurations.

Inputs are individually monitored for a fault condition. A fault will be announced with its respective yellow fault LED and will activate the Fault Module. The detector power output fuse is monitored and rated for 2 amps.
