Series CMT Carbon Monoxide Transmitter

Current/Voltage Output, 125 PPM Range

The Series CMT Carbon Monoxide Transmitter accurately detects and transmits low concentrations of carbon monoxide inside a parking garage or loading dock. Transmitters can be ordered in wall mount or duct mount configurations. Universal current and voltage outputs are field selectable and match most common building management controllers. Optional relay and alarm buzzers are available on the wall mount models to directly connect to a warning light or exhaust fan. The Series CMT can be field calibrated using internal potentiometers. Software settings such as set points for optional relay outputs are password protected.
