Product overview
Cubic JM-AM4302R is a battery powered CO alarm with relay developed based on electrochemical technology, especially designed for CO leakage detection in indoor environments.


JM-AM4302R embedded with Cubic self-developed electrochemical CO sensor, offers high stability, selectivity, and repeatability for CO leakage detection while minimizing interference from gases such as acetic acid and ethanol. It also provides high detection accuracy across the full temperature range and measurement span, ensuring reliable and durable performance in diverse indoor conditions. 


Cubic JM-AM4302R responds rapidly to elevated CO levels, providing early warnings through audible and visual alarms with a sound output of up to 85 dB. It will be triggered automatically when dangerous CO concentrations are detected, following graded thresholds of 50 ppm, 100 ppm, and 300 ppm, in compliance with safety standards.


The alarm includes self-checking and silence button functions for simple and convenient operation. It is battery-operated with a lifetime of up to 10 years, supporting long-term, maintenance-free application. A relay signal output is also available, allowing integration with external control systems for extended functionality.


JM-AM4302R is fully compliant with UL2034, EN50291, and RoHS standards. OEM/ODM turnkey solutions are available for flexible customization. With the compact design, it is easy to install on walls or other surfaces, suitable for a wide range of indoor environments.
