AO-BH-H9 Domestic Gas Alarm for Methane.
Domestic gas alarm with TDLAS laser methane sensor, fast response and 4G support for homes, hotels and apartments.
The BH-H9 is a domestic gas alarm designed for indoor methane detection. It uses a TDLAS laser sensor with long service life and stable operation for residential, hotel and apartment installations.
Its low-maintenance design delivers high sensitivity, fast response and strong resistance to common interference such as cooking fumes or moisture. It also supports 4G networking, a 12 V active output for driving solenoid valves and one passive relay output for system integration.
- Laser sensor dedicated to methane measurement
- Sensor life up to 10 years
- Strong resistance to fumes, water vapor and other interference
- Fast response with audible and visual alarm
- 4G support and outputs for automation
