Installation Guide

Optional Dry Contact Relay Output Operation

1. When connecting the relay output to an external building automation system (BAS) or alarm, it

is recommended that the Common and Normally Closed contacts be used. This allows the

external system or alarm to detect when the cabling is cut.

2. During a clog alarm, the relay will activate for one second, opening the Normally Closed

contacts, and closing the Normally Open contacts.

3. Note: If the power is lost, there will be no relay indication of such power failure.
