Dedicated Auxiliary Output (X800)
The dedicated Auxiliary Output has a maximum output current of 3A
can be used for devices such as door holders, DACT, or RDT. The output is power
limited and supervised for overcurrent and direct shorting. To configure the output to
shut down during AC loss to conserve battery, the Zeus configuration tool must be
used.
If the output is configured to turn off on battery, then the output is used for
supplementary purposes only.
are drained, more current needs to go to charging the batteries. Therefore, if
the NACs are configured as Auxiliary Outputs, they will be turned off while the
batteries charge. The OI will display an overcurrent condition. After the
batteries make it to float, the trouble will go out and the Auxiliary Outputs will
return to ACTIVE. The dedicated Auxiliary Output (X800) will remain on, even
if the battery charger is active. It is only NACs configured for Auxiliary Output
that are affect by the battery charger priority.
Wiring the Dedicated Auxiliary Output
X800 Pins 3 and 4 are connected internally to Pins 1 and 2 respectively and are
used for ease tapping the output power to internal or external devices. Faults on
any terminal can affect all devices connected on 1,2 and 3,4.
