Macurco CM-12 — line voltage carbon monoxide detector, controller and transducer from the Macurco 12-Series, dark gray.
It measures CO in parking garages and boiler rooms, working alone or as an analogue transducer feeding a control panel. A 5 A fan relay starts exhaust plant directly, a separate alarm relay drives warning devices, and a 4 to 20 mA loop reports concentration. It mounts on a 4 by 4 box and becomes its cover.
- Power 100 to 240 VAC, 50 to 60 Hz, 1.0 A maximum
- Displays 0 to 200 ppm CO; electrochemical sensor rated 7 years and over
- Fan relay 5 A, 240 VAC pilot duty, SPDT; actuation 15 to 100 ppm, 35 ppm default
- Alarm relay 0.5 A, 120 V, 60 VA, N.O. default or N.C.; 50 to 200 ppm
- Buzzer 85 dBA at 10 cm and 3 digit LED display, both off by default
- 0 °F to 125 °F, 10 to 90% RH; 4-1/2 × 4 × 2-1/8 in.
- ETL Listed, certified to CAN/CSA C22.2 No. 61010-1, conforms to UL 61010-1
The 4 by 4 box is not included. The low voltage twin is the CM-6, and Macurco lists UL 2075 for the CM-6 only, not for this model. GD-12, TX-12-ND, RD-12, CD-12 and OX-12 cover other gases on the same platform.
