Combination photoelectric smoke and rate-of-rise heat fire alarm detector with a sealed 10-year lithium battery — install and forget. Detects both smoldering smoke and rapid temperature rise, with a loud audible alarm, visible LED indicator and test button. For homes, apartments, hotels, offices, warehouses and commercial buildings. CE and FCC certified. MOQ 100 units for B2B export from China.
A fire alarm detector is the first line of life-safety defense in any occupied building, and combination units that sense both smoke and heat give faster, more reliable warning than single-sensor alarms. This detector pairs a photoelectric smoke chamber — ideal for slow, smoldering fires that produce visible smoke with little heat — with a rate-of-rise heat sensor that triggers when temperature climbs rapidly, catching fast-flaming fires.
The sealed 10-year lithium battery eliminates annual battery changes and the most common cause of alarm failures (missing or weak batteries). A single Test button verifies sensor function, a status LED shows normal, alarm and low-sensitivity conditions, and the built-in piezo horn reaches 85 dBA for reliable nighttime alerting. The compact ceiling-mount design installs in minutes with no wiring.
Chinese alarm and sensor manufacturers, based in Guangdong, Zhejiang and Jiangsu, supply photoelectric smoke detectors and combination heat-smoke units to North America, Europe, the Middle East, Australia and Africa. Options include 10-year sealed battery, 9V replaceable battery, low-voltage wired, and interconnected (multi-unit) models, with CE, FCC and EN 14604 certification paths.
