Connecting the ALARM I/O port

Alarm inputs and outputs are supplied via a 25-pole D-type socket. The screw terminal input/output
connection board supplied with the unit simplifies all alarm connections to the unit.

3.10.1 Connecting the Inputs
Each (alarm) input line can be switched by a relay contact from devices such as pressure pads,
passive infra red detectors, smoke detectors and similar devices.
Wire them as either N/O (Normally Open) or N/C (Normally Closed). You can configure the alarm
inputs as N/O or N/C in the menu system. The default is N/O.
3.10.2 Connecting the Alarm Outputs
The eight alarm output relays respond to input alarms and triggers. You can configure the alarm
outputs as N/O or N/C in the menu system. The relays are active for the duration of the driving
event. Connect the application to the alarm output relays (resistive loads only). Do not exceed 1A
30V DC, 0.3A 125V AC on an alarm output relay's contacts. The contacts must not be used at AC line
voltages.
