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 screwdriver 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
2.5 to 0.2 mm2.
