Set Up Contacts and Relays

The System 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 and a user-defined normal state. Output contacts can map internal alarms and events to outside devices.

See the Installation Manual to connect contacts and relays to your Programmable Customer Input/Output Module (PCIOM).

Input contacts

Path: Main > Setup > System # > Input/Output > Input Contacts

Each Main Module supports up to 16 user-defined input contacts. Each contact monitors a sensor and responds to changes in the state of the sensor (open or closed).

Name. Provide a unique name for each input contact.

Normal. Choose the normal state of the sensor. If the state changes, the controller takes the action defined by the Alarm Map setting.

Delay. Set how long the contact should be out of its normal state before the controller takes action (controlled by the Alarm Map setting).
