SR-824THS 2-in-1 CO and Smoke Detector with DC3V Batteries CE Certified
Battery-powered 2-in-1 CO and smoke detector with LCD display, dual sensors and sound-light alerts for safety projects.
Main features:
- Dual CO and Smoke Detection
Combines an electrochemical carbon monoxide sensor with an infrared photoelectric smoke sensor for reliable detection of both CO leaks and early-stage fire smoke. - Microprocessor-Controlled Detection
Intelligent microprocessor control provides stable operation, accurate signal processing and reduced sensitivity drift during long-term use. - Real-Time CO Concentration Display
The built-in LCD displays carbon monoxide levels from 0–999 ppm, allowing users to monitor environmental conditions more clearly. - Low-Power Battery Operation
Powered by three 1.5V AA batteries, with quiescent current below 80 μA, making it suitable for apartments, hotels, residential projects and other locations without fixed wiring. - Audible, Visual and Low-Battery Alerts
Provides sound and LED warning signals when smoke or carbon monoxide is detected, together with a low-battery alert for timely maintenance and dependable operation.

FAQs：
1. What does the SR-824THS detector monitor?
The SR-824THS simultaneously monitors carbon monoxide and smoke. It combines an electrochemical CO sensor with an infrared photoelectric smoke sensor for dual-hazard detection.
2. What is the carbon monoxide detection range?
The built-in LCD displays carbon monoxide concentrations from 0 to 999 ppm, allowing users to check real-time CO levels and identify potential leakage risks.
3. How is the SR-824THS powered?
The detector operates on three 1.5V AA batteries. Its quiescent current is below 80 μA, supporting low-power operation. Batteries are not included with the standard product.
4. What alarm and maintenance indicators are provided?
When CO or smoke is detected, the device provides audible and visual warning signals. It also includes an LCD concentration display and a low-battery warning for timely maintenance.
5. Is the SR-824THS suitable for OEM, ODM and bulk projects?
Yes. OEM and ODM options can include customized branding, packaging and instruction manuals. MOQ, sample availability, lead time and customization requirements can be confirmed according to the project.
