The Contact Closure Module, is a low cost, plug-in Powerline Carrier Receiver Module that provides a set of isolated Relay Contacts (Form C), (NO-C-NC), that switch when the unit is activated. It plugs directly into the 120V AC outlet, and receives its turn-On commands over the existing AC power wiring from remote Powerline carrier Transmitters.
The CCO Module has a Dip switch that is used to select the code to be monitored. It will only respond to those transmitters whose code setting match its own. All other transmitter signals will be ignored.
With this unit you can monitor as many transmitters as you like as long as they all have the same code setting.
Use with the Smoke Alarm Interconnect Module to connect your existing house smoke detectors to your alarm system - or buy a CT-SAI-KIT (includes SAI Module and CCO Receiver.)
