Onguard 800 System Input Vote Module

Model 1530 Input Module is a primary detector module that accepts two independent dry relay contacts from initiating devices. This module can vote between its local two input channels as well as other Input Vote Modules, requiring the combination of up to four valid alarms to confirm the alarm condition. The voting configuration can trip the Alarm, Release and Relay Modules based on DIP switch settings.

Inputs are individually monitored for a fault condition. A fault will be an-nounced with its respective yellow fault LED and will activate the Fault Module. The detector power output fuse is monitored and rated at 3A.
