WARNING: The maximum rating of all the relays is 500mA @ 48V, exceeding this load will cause
damage to the relays.
Connecting 485-bus devices
The unit uses the 485-bus networking system to allow multiple units, remote keyboards, alarm
modules, video switchers, and other accessories to be connected together. The total length of the
485-bus network can be up to 1500m (4900ft).
Connecting additional alarm modules
Optional alarm modules (DM/CI01) can be added to the unit to increase the number of alarm inputs.
The unit can support multiple alarm modules connected to the 485-bus.
To add alarms:
1. Connect the corresponding alarm contact to the alarm input, i.e. Alarm 2 would be
connected between ground (GND) and A2.
