Customizing and Updating the ATS
How to Connect User Input Contacts and Relay Outputs to the ATS
Overview
The ATS can monitor external contact closure events. Possible applications include:
•Magnetic contact switches
•Window foil
•Tamper switches
•Heat detectors
•Water sensors
•Pressure sensors
•Building smoke and fire detection systems
You can set input contacts to cause alarm conditions based on their current state in relation to a user- defined normal state. Relay outputs can map internal alarms and events to outside devices (see “Contacts & Relays” on page 46 for information about setting up alarms).
Make contact closure connections (NO or NC) at the user interface circuit board located on the user connection plate. You can make eight connections— four input contacts and four relay outputs. The user connection plate is on the roof of the ATS enclosure.

The terminal block on the user interface board accepts wire sizes from 12 to 30 AWG or 2.5 to 0.2 mm2.
Note
You can make these connections from inside the enclosure, or you can remove the user connection plate from the ATS to make the connections. A Phillips or standard screwdriver is needed to loosen the two captive screws. Use the knockout in this plate to route cables to the user interface board. If you decide to remove the plate, make sure not to disturb the existing connections.
