Macurco CM-E1 is a low-voltage carbon monoxide detector for residential and light commercial spaces, designed to connect to fire and security alarm control panels. It is UL 2075 certified and approved by the California State Fire Marshal, has a 10-year sensor with end-of-life signal and needs no calibration. Alarm and trouble relays tie into any fire or burglary panel for local and remote monitoring, and an 85 dB local sounder gives a Temporal 4 alarm.

Installation notes
- Wire to a normally open initiating circuit on a UL certified alarm control panel
- Power from a battery-backed 12 or 24 VDC supply, fused or current limited at 0.2 A for each CM-E1
- Clip-in wire harness allows the detector to be replaced without rewiring
- The CM-E1 is the rectangular wall model for flush or surface mounting; CM-E1-RF and CM-E1-RS are the round ceiling flush and surface versions

FAQ
Will the CM-E1 work with my alarm panel?
It is designed for UL certified fire and burglary control panels. The alarm relay connects to a normally open initiating circuit, and a separate trouble relay is provided.
What power does it need?
9 to 32 VDC from a battery-backed 12 or 24 VDC supply, fused or current limited at 0.2 A per detector. It draws 15 mA normally and 35 mA in alarm.
Does it need calibration?
No. The sensor needs no calibration and has a 10-year life with an end-of-life signal.
Is there a ceiling mount version?
Yes. The CM-E1-RF (round flush) and CM-E1-RS (round surface) are the ceiling mount versions; the CM-E1 is the rectangular wall mount model.
