Model Number: HM-621THS 160223
Brand Name: HEIMAN
Key Specifications/Special Features:
Smoke and CO detector (independent)Introduction:This product is a combination unit of smoke and carbon monoxide detectorSmoke chamber using the principle of smoke particles reflecting infrared lights can accurately detect the early smoke of a fire and the gas detection adopts a carbon monoxide electrochemical sensor to ensure stable and constant performanceWhen concentration of the leaked carbon monoxide or smoke density reaches the given alarm level, the detector LED flashes red and buzzer gives out alarm sounds
Besides suitable for early warning and protection of carbon monoxide leakages or fires in houses, villas, factories, shopping malls, warehouses, office buildings
Indoor places, this unit has a subtle shockproof design, which makes it also suitable for vehicle use
