System Sensor CO1224A Carbon Monoxide Detector


Protect your home from carbon monoxide leaks with System Sensor’s CO1224A carbon monoxide detector. A colourless, tasteless and odourless gas that’s highly toxic, carbon monoxide is highly dangerous and can only be detected using a specialized device.

The CO1224A uses electrochemical sensing technology that lets it provide an early warning. It’ll alert residence by sounding and flashing a temp-4 alarm. The unit’s trouble relay lets it send a sensor failure or end-of-life signal when connected to an alarm or automation system. As a low voltage detector, it allows for multiple units to be connected to a panel without the need for additional power supplies or the need to upgrade to a more expensive panel.
