Relays and Contacts

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
