SR-822THS Carbon Monoxide & Smoke Detector Combo with Standalone Battery
SR-822THS is a battery-powered smoke and carbon monoxide detector featuring dual-sensor technology, low power consumption and compact installation for residential and commercial safety projects.
Main features:
Dual Smoke and Carbon Monoxide Detection: Combines smoke detection and carbon monoxide monitoring in one standalone device, helping reduce installation complexity and procurement costs for residential and commercial safety projects.
Dual-Sensor Detection Technology: Uses a semiconductor smoke sensor together with an electrochemical CO sensor to provide stable detection performance with low sensitivity drift.
Microprocessor-Controlled Performance: Built-in microprocessor control continuously processes sensor signals, improving operating stability and supporting reliable alarm response in everyday environments.
Low-Power Standalone Battery Operation: Powered by three 1.5V AA batteries with a standby current below 105μA, making the detector suitable for locations where fixed wiring is unavailable or inconvenient.
Wide CO Monitoring Range and Environmental Adaptability: Supports a carbon monoxide detection range of 0–999 ppm, recovery within 30 seconds, and operation from −10°C to 50°C at 10%–95% relative humidity.
