FAQs：
1. What type of sensor does the SR-907-2 use?
The SR-907-2 uses a high-stability electrochemical carbon monoxide sensor. It provides accurate CO detection and is designed for an approximate service life of three to five years.
2. What are the carbon monoxide alarm response levels?
The specified alarm response times are:
- 30 ppm: after approximately 2 hours
- 50 ppm: within 60–90 minutes
- 100 ppm: within 10–40 minutes
- 300 ppm: within 3 minutes
These staged response levels help provide appropriate warnings at different CO concentrations.
3. How is the detector powered?
The detector operates with three 1.5V AA batteries. Its standby current is no more than 10μA without the LCD and no more than 15μA with the LCD. Alarm current is no more than 25mA.
4. What are the recommended installation conditions?
The SR-907-2 is designed for ceiling mounting. Its operating temperature range is −5°C to 40°C, with a recommended relative humidity range of 20%–90% RH. The product measures approximately 100 × 38mm.
5. Can the SR-907-2 be customized for wholesale or project orders?
OEM and ODM options may include customized logos, packaging, user manuals and labeling. Sample availability, MOQ, production lead time and required certification documents should be confirmed according to the destination market and project requirements.
