External I/O connection

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.

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 or N/C. You can configure the alarm inputs as N/O or N/C in the menu system. The default is N/O.

Connecting the Alarm Outputs

The four 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 30 Vac, 40Vdc, 500 mA (continuous) or 10VA on an alarm output relay's contacts. The contacts must not be used at AC line voltages.
