CO-S-D Carbon Monoxide & Smoke Detector

Carbon Monoxide & Smoke Detector


The Carbon Monoxide & Smoke Detector (CO-S-D) combines two important safety devices in one unit. The CO-S-D detects and announces unsafe carbon monoxide levels and smoke or fire. This safety device features a voice warning system that announces the detected hazard to eliminate confusion. The unit will beep and announce “FIRE!” or “WARNING! CARBON MONOXIDE!” depending on the threat.

This battery-operated unit will continue monitoring even during a power outage, when many fire and carbon monoxide incidents may occur. The detector’s battery door will not close if the batteries are not properly installed, making upkeep easy. Staff can temporarily silence nuisance alarms to avoid desensitization and annoyance.
