How to Connect User Input Contacts and

Relay Outputs to the ATS

Overview

The ATS can monitor external contact closure events. Possible applications include the following:

• 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 and a user-defined

normal state. Relay outputs can map internal alarms and events to outside devices. See “Contacts &

Relays” on page 46 for information on setting up alarms.

Make contact closure connections (NO or NC) at the

user interface circuit board on the user connection plate.

(See figure at right.) You can make eight connections—

four input contacts and four relay outputs. The user

connection plate is on the roof of the ATS enclosure. For

more information on the user connection plate see “User connection plate” on page 16.

You can make connections from inside the enclosure, or you can

remove the user connection plate and make your connections.

Remove the plate using a Phillips or standard screw driver to

loosen the two captive screws. Use the knockout in the plate to

route cables to and from the user connections on the plate. If you

remove the plate, make sure that you do not disturb the existing

connections.

Note

The terminal block on the user connection plate accepts wire sizes from

12 to 30 AWG or 2.5 to 0.2 mm
