Note:
1) Before testing, turn on the power switch.
2) Please install the smoke alarm on the ceiling so that when smoke occurs, the detector can better detect the smoke and sound the alarm in time.
3) During testing, place the smoke alarm vertically or mount it on a board.(Since the sensor is located on the side edge, direct smoke toward the sensor from the side edge.)

How to Test a Smoke Alarm for Effectiveness Before Installation?
Correct Testing
After turning on the battery switch, ignite a piece of paper. As the paper burns and produces smoke, hold the smoke detector vertically above it, as shown in the diagram. The alarm will sound once the detector detects smoke.

Incorrect Testing
Placing the smoke alarm horizontally above a burning piece of paper is an incorrect testing method. During the test, the area above the alarm is open air rather than a ceiling, with no barrier to trap and concentrate the smoke. As a result, the smoke cannot enter the alarm’s smoke detection chamber (located at the edge of the smoke alarm), so it will not trigger an alarm.
When the smoke alarm is properly installed on a ceiling, smoke is blocked and concentrated around the unit by the ceiling surface, allowing it to enter the detection chamber and activate the alarm as intended.

1️⃣Installation
1) Take out the product and detach the mounting plate.
2) The battery pin (red) is OFF at beginning as figure.Turn it ON the battery pin will be moved into the pin
groove position as figure.
3) Choose a suitable installation position.
4) According to the holes of mounting plate, drill a hole in the needed place of ceiling and stuff the plastic nail seat into the hole.
5) Use the screw to fix the mounting plate onto plastic nail seat.
6) Embed the two snap joints on the detector base into the detector slot. Turn the product clockwise in order to fasten it to the mounting plate tightly.
7) Test after the installation. Press the test/hush button, if the red indicator light flashes quickly and continue alarms at the same time, it means the detector is working properly. At the same time, the detector enters low sensitivity detecting state, the red LED light flashes every 10 seconds. About 9 minutes later, it enters normal detecting state from low sensitivity detecting state automatically. Or press the test/mute button again and cancel low sensitivity detecting state.
2️⃣Button Test
Press the test/mute button, if the red indicator light flashes quickly and meanwhile alarm is given, it means the detector is working properly. At the same time, the detector enters low sensitivity detecting state. About 9 minutes later, it enters normal detecting state from low sensitivity detecting state automatically.
3️⃣Low sensitivity detection (silent mode)
1 )Use a small amount of smoke to make the detector alarm, and press the test/mute button. Then the detector will enter low sensitivity detection and exit alarm state. The detector is silent (and will enter normal detection state after 9 minutes), and won't alarm until smoke concentration is higher.
2 )Press the test/mute button again and you can cancel low sensitivity detection. The detector will enter normal detection state.
Note: After canceling low sensitivity detection, if there is some residual smoke, the detector will continue to alarm.
4️⃣Alarm memory
After alarm is made, the detector will have alarm memory. The green LED will flash every 1.3 seconds for 3 times, which will last for 43 seconds. So the user can tell if the detector has entered alarm state from a distance without touching the detector. LED display will quit after 24 hours. The first time you press the test/mute button after alarm is made, the detector will hint by special alarm mode. After releasing the test/mute key, alarm memory will be purged. Then you press the test/mute button and it will be normal key test.
5️⃣Failure analysis and elimination
Failure phenomenon | Analysis of cause | Elimination method |
No response of the TEST key | Battery Red pin is OFF, detector is closed | Remove battery pin to ON |
Circuit faultor battery fault | Looking for manufacturers or professional services | |
Alarm about every 344S | Battery low voltage | Looking for manufacturers or professional services |
