Power supply wiring
HSM2300/2204
The HSM2300/2204 power supply/high-current output module provides up to 1 A of additional current and can be used to add up to
four programmable outputs (HSM2204 only) to the alarm system.
The 4-wire Corbus connection provides communication between the module and alarm panel. Connect the RED, BLK, YEL and GRN
terminals to the Corbus terminals on the alarm controller. If O1 is not used, connect to Aux+ with a 1 K resistor. Board current draw is
35 mA. Battery standby capacity is at least 24 hours for fire applications. Recommended battery is DSC model BD7-12.
Note:
All terminals are Class 2 power limited, except battery leads.
