Low Voltage Alarm Smoke and CO Detectors
These low voltage wired smoke detectors and carbon monoxide detectors are designed to be used with security systems and alarm systems. We stock both 2 wire smoke detectors and 4 wire smoke detectors. 2 Wire Smoke Detectors use the same pair of wires to provide power from the alarm system as well as signalling in case of a fire. 4 Wire Smoke Detectors use a pair of wires for power and a pair of wires for a zone connection to the alarm system. Low voltage carbon monoxide detectors are typically 4 wire devices with 2 wire used for power and 2 for the zone signal.
