MX 850PC Addressable, Triple Sensor (Photoelectric, Carbon Monoxide, Heat Detector) (516.850.054.E)

For life protection and when the environmental conditions are challenging, the 850PC detector provides the ultimate in detector performance and nuisance alarm rejection. It is a multi-sensor that monitors smoke, heat and CO levels in concert to accurately determine the presence of fire. Its nuisance alarm rejection properties make it the ideal choice for hotel bedrooms where steam from bathrooms is a common source of nuisance alarms. All the 850 Series detectors feature a built-in short-circuit line isolator which is active when the detector is used with a 4B-C base.
