Onguard 800 System Fault Module

The Fault Module is a common system annunciator triggered by any faults in the system. All faults are displayed locally on each module but are also transmitted centrally to the Fault Module, sounding a sonalert. The sonalert can be silenced while determining the source of the fault. A fault will be noted with the system fault LED and de-energize the failsafe fault relay output.

A protection circuit monitors the power supply voltage for under or over voltage inputs. Should the power supply voltage deviate from its required specification, the system fault LED will illuminate and the sonalert will sound, followed by the relay changing state.

An auxiliary normally closed input is provided to monitor any dry contacts. If the contact is open, the auxiliary LED will illuminate and the sonalert will sound followed by the relay changing state.
