INSTALLATION

1. Avoid installations in places with stagnating smoke, heavy

dust, heavy water mist, heavy oil mist, great humidity

(>95%) and high wind speed (>5m/s).

2. Insert the ready battery into the .

Choose a proper position. Normally, the center of the

detection area ceiling is recommended. Fix the detector base

into the chosen position. Then put the detector into the base

and twist to fasten it. Be sure it is fastened tightly.

PRODUCT INTRODUCTION

PRODUCT PROFILE

FEATURES

This product is a battery operated photoelectric smoke

detector. The smoke chamber using the principle of smoke

particles reflecting infrared lights can accurately detect the

early smoke of a fire. When concentration of the leaked

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 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.

OPERATING PRINCIPLE

1. Insert the 2pcs 1.5V AA batteries into the battery

compartment. The detector enters into normal working

status. The LED flashes green once every 30s, indicating

normal power supply.

2. The detector should be tested periodically during use. Short

press Test & Hush Button to run a test. The LED flashes Red

along with buzzer sounding for alarm indication. Do not test

the detector too often to save battery life. One a month is

recommended.

3. During alarming status, short press the Test & Hush Button.

Then the detector goes into mute status. The LED keeps

flashing red while the buzzer will stop sounding. If the alarm

status hasn’t been reset , the mute status wil l end

automatically in 10 minutes later. The buzzer sounds again.

If the alarm status is reset during the 10 minutes, the detector

recovers to normal working status.

4. The detector can auto check open circuit, short circuit and

other malfunctions in smoke chamber. During malfunction,

1. Replace the batteries with new ones in time on low battery

condition to ensure normal operation.

2. No block within a radius of 0.5m from the detector.

3.The horizontal distance from the detector to the air

conditioner outlet should not be less than 1.5m.

4. If needs to install the detector in an aisle ceiling with a width

less than 3m, choose a center position. Keep the distance

between the detectors less than 15m. The distance from the

detector to the end wall should not exceed half of the

distance between the detectors.

5. Clean the detector surface with soft brush every month to

EMERGENCY ALARM TREATMENTS

NOTES

Treatments when a smoke alarm is reported:

1. Inspect the causes. If it is caused by cigarette smoking or

other reasons and not a fire alarm, just remove the smoke

resource and the alarm will reset. If it is a false alarm, check

if the installing position is improper.

2. If a fire breaks out, in the early stage, use a fire extinguisher

to put out the fire.

3. If the fire is large, don’t panic. Escape asap and then call the

police.
