Heiman HM-621THS User Manual

PRODUCT INTRODUCTION

This product is a combination unit of smoke and carbon
monoxide detector. The smoke 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
performance. When 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 etc. indoor
places, this unit has a subtle shockproof design, which makes it
also suitable for vehicle use.

INSTALLATION

1. Since Carbon Monoxide is a little lighter than air and smoke
generated in fires will rise in the air, normally the detector is
installed in a higher position. For wall mounted, install at
about 0.3-1.0m from ceiling. For ceiling mounted, normally
install at the ceiling center of the protected area (refer to the
following image)

2. Fix the detector base into a wall or ceiling with screws and
fasten the detector head on the base.
3. While installing at home, keep the detector away from your
gas stove to prevent flame roasting. Avoid installing in
places with heavy oil or smoke that may cause false alarm or
block the gas convection holes and influence the detector
sensitivity. Also do not install the detector near to exhaust
fans, windows, doors and in places with great vapor in
bathrooms.

OPERATING PRINCIPLE

1. Insert 2pcs 1.5V AA batteries into the battery compartment.
The detector enters into warm-up status. LED flashes Green.
2. About 3 minutes later, the flashing Green LED goes out. And
the detector goes into normal working status.
flashes Green once every 30s, indicating normal battery
supply.
