D9124 Operation & Installation Manual
Page 62
Description
The D9142 is a supervised, 4 Amp 24 volt power supply. The D9142 charges standby
batteries and supplies power to auxiliary devices.
The D9142 connects to a dedicated circuit breaker. 120 VAC input terminals on the D9142
are covered for added safety. The D1601 transformer is fused with a thermal non resettable
fuse. The transformer plugs into the D9142 using an input/output cable and provides AC
power for the D9142 and a 16.5 VAC 40 VA output for powering the control/communicator.
The D9142 supervises all stages of power for detection in case of a fault.
You can select which trouble events activate a supervision relay output. The relay output
allows for a remote indicator of general trouble with the D9142's AC power, battery, or power
output.
Battery Supervision
The D9142 offers low battery and missing battery supervision for both batteries.
When the battery drops to 22 - 24 VDC, or the battery is disconnected, the red Low Battery
LED lights and the power supply triggers the Low Battery Trouble output.
When battery voltage returns to 24.2 - 26.5 VDC, the Low battery LED turns off. The D9142
resets the Low Battery Trouble output.
