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.
