The alarm output provides a variety of relay contact outputs that indicate the
status of the power supply. The relay contacts are rated for a maximum of 1A at
30 VDC. The alarm output connector also provides a means of remote power

Remote On/Off Control
(if used). The “Alarm Output” connector also provides
for remote on/off control of the Power Supply. Remote on/off control is
configured with a jumper on a pin header on the main Alarm Output circuit
board. The default configuration is with remote control disabled. The remote
control can be configured “normally off” or “normally on” by the jumper setting
(see Figure 7). To access the jumpers the cover will have to be removed from the
HLC Power Supply or (legacy) Remote Display Module. Disconnect all input
power, then remove the six screws securing the cover and slowly and carefully
remove the cover.
