{"title":"Four Wire Type Smoke Detectors System Sensor DSC","description":"\u003cp\u003eFour-Wire Type Smoke Detectors can be used if you're looking to separate out different areas or levels of the building and want to know where a fire may have started. These use two wires for powering the smoke and two more wires to run back to your alarm panel zone. These can also sense heat and sound off if the right model is being used.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003eIt is recommended that you use the System sensor \u003ca title=\"System Sensor SYS-EOLR1 Power Supervision Module For 4 Wire Smokes\" href=\"https:\/\/www.alarmsystemstore.com\/products\/system-sensor-sys-eolr1\"\u003eSYS-EOLR1\u003c\/a\u003e Power Supervision Relay with all four-wire smoke chains.

This is compatible with most hardwired alarm systems. You will have to use a control module. For the COSMO-4W you will use the COSMOD4W 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.\u003cbr\u003e\u003cbr\u003eWhen 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.
