System Sensor i4 Series 2-wire Smoke/CO Detector

If you're looking for an aesthetically pleasing, cost effective solution to detecting smoke and carbon monoxide then the System Sensor i4 Series Smoke/CO Combination detector is what you've been looking for.

The COSMO-2W is a 2-wire smoke detector with built-in carbon monoxide detector. This is compatible with most hardwired alarm systems. You will have to use a control module. For the COSMO-2W you will use the COSMOD2W control module. The module is the interface between the detector and the panel. It allows a 2-wire or 4-wire device to communicate distinct smoke, maintenance and CO signals to the panel while reducing wiring requirements as compared to separate smoke and CO devices. The modules can handle 12 devices on a loop. In addition to that all COSMOs have a built-in sounder allowing the COSMOD module to act as a reversing relay, setting off all of the detector sounders at once.

When you run back to the main control panel from the module you will have two wires for power, two wires for the smoke zones, and 2 wires for the CO zones. The module will derive its power from your panel's auxiliary power terminals.

QUESTIONS & ANSWERS

Ask a Question
  • Can I use this relay with a Honeywell VISTA-20P Ademco Control Panel, PCB in Aluminum Enclosure?

    Yes, the COSMOD works well with Honeywell, but you will need a relay on the Honeywell to power the COSMOD such as the ones on the 4229 expander and the 4204 relay board.
