Relays and Contacts

Overview

The controller board provides connectors for output relays and input contacts. The connectors can be

used with any dry-contact sensors. The connectors are designed to monitor circuits that have no voltage

potential of their own. Connecting the contact or relay to any circuit other than a dry closure connector

may result in damage to the main control board.

You can connect any normally open (NO) or normally closed (NC) dry contact sensor, including:

• magnetic contact switches

• window foil

• tamper switches

• heat detectors

• water sensors

• pressure sensors

• smoke detectors

Output relays

This figure shows the four positions on the output relay connector and provides the individual pin

assignments for each position.

Note: The terminal block

accepts wire sizes from 1.6mm

(14AWG) to 0.4mm

(26AWG).

Electrical Hazard: Control board connections should be made only to Class 2 circuits.
