Macurco CM-E1R Security Series Carbon Monoxide CO Gas Detector

The Macurco CM-E1R is a UL2075 listed gas detector designed for residential and light-commercial environments. It provides reliable detection of carbon monoxide with low voltage power (9-32 VDC) and integrates into fire or security control systems for local and remote monitoring. With a round housing option and flush or surface mount capabilities, this detector blends safety and aesthetics.

The built-in electrochemical sensor offers up to 10 years of service with an end-of-life indicator, reducing the cost and hassle of frequent replacements. There is no calibration needed, and it features a clip-in wire harness for easy in/out wiring. A loud Temporal-4 sounder and LEDs indicate alarm, trouble, and power status. This unit also includes both alarm and trouble relays to tie into control panels.

Made in the USA, the CM-E1R is ideal for bedrooms, offices, common areas or hallways. It provides audible and visible alerts when carbon monoxide levels exceed UL 2034 limits, helping ensure safety in inhabited spaces.
