Alarm inputs and outputs are supplied screw down terminal blocks. The screw terminal blocks 

are supplied with the unit.

Each (alarm) input line can be switched by a contact from an external device between an 

numbered input and ground (G). Wire them as either Normally Open (N/O) or Normally 

Closed (N/C). Configure the alarm inputs as N/O or N/C in the menu system. The default is N/

O.

Alarm input impedence: Internal pull-up 10 kOhm to +5 V

Input voltage range: -2 VDC minimum to 15 VDC maximum

Input voltage threshold: low voltage 0.5 V maximum, high voltage 2 V minimum

Cable cross section: AWG 26-16 (0.13-1.5 mm2)

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. 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.

Switching current (resistive): 500 mA maximum

Switching voltage (resistive): 30 VAC/40 VDC maximum

Cable cross section: AWG 26-16 (0.13-1.5 mm2)

Alarm input connector for 16-channel model

Alarm input connector for 8-channel model

Electrical voltage.

Risk of electric shock and damage to the unit.

The contacts must not be used at AC line voltages.
