Carbon monoxide alarms incorporate a CO sensor, control components and an alarm notification appliance in a single unit. These devices may be either battery powered or connected with permanent wiring to an ac or dc power source. Standby (battery) power is provided on all ac powered CO alarms. CO alarms are intended for installation in dwelling
Photoelectric Smoke Detector: A light source is aimed into a sensing chamber. The light source is angled away from the actual sensor inside the detector. When smoke enters the chamber, though, the light reflects off the smoke and onto the sensor, which sets off the alarm. Dual-Sensor Smoke Alarms: These feature both ionization and photoelectric How Carbon Monoxide Detectors Work. Carbon monoxide detectors work by recognizing gases that people can’t smell or see. These detectors are very sensitive, but to work optimally they must be properly placed. Since they are designed to alert the homeowner before the carbon monoxide reaches deadly levels, they need to be at head level or lower.An integrated system of smoke and carbon monoxide detectors, regardless of whether they are wired or wireless, means that your alarms work in tandem. When one sounds an alert, each alarm goes off. Should a unit be triggered in your kitchen, maybe because you forgot about dinner in the oven, every unit in the house will ring.
Digital LED display shows the level of carbon monoxide the CO alarm is sensing ; 85-decibel alarm announces when carbon monoxide is detected ; Peak Level Memory records the last time carbon monoxide was detected or when the unit was last tested ; Test-Hush Button makes testing the detector or silencing false alarms easy
