External alarm 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 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. Configure the alarm inputs as N/O or N/C in the menu system. The default is N/O. Inputs
9-16 have no function on an 8-channel analog unit.
Specifications
Alarm input impedence: Internal pull-up 10 K to +5 V
Input voltage range: -5 VDC minimum to 40 VDC maximum
Input voltage treshold: low voltage 0.8 V maximum, high voltage 2.4 V minimum
Cable cross section: AWG 26-16 (0.13-1.5 mm
Connecting the alarm outputs
The four alarm output relays respond to input alarms and triggers. 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. Only connect resistive loads to the alarm output relays. Do not exceed 30 Vac, 40 Vdc,
500 mA (continuous), or 10 VA on an alarm output relay's contacts.
