RF Create a group in the first use (i.e. 1/2)
Take any two alarms that need to be set up as groups and number them as " 1"
and "2" respectively.
1. Devices must work with the same frequency. 2. The distance between the two devices is about 30-50CM.
3.Before pairing the smoke detector, please insert 2 AA batteries correctly.
After hearing the sound and seeing the light, wait 30 seconds before performing the
following operations.
4. Press the "RESET button" three times, the green LED lights up means it is in
networking mode.
5. Press the “RESET button” of 1 or 2 again, you will hear three “DI” sounds, which means the connection starts.
6. The green LED of 1 and 2 flashing three times slowly, which means that the
connection is successful.
[Notes and Notices]
1. RESET button. (Figure 1)
2. Green light.
3. Complete the connection within one minute. If exceeds one minute, the product identifies as timeout, you need to re-connect.
How to Added more alarms to Group (3 - N)
1. Take the 3 (or N) alarm.
2. Press the "RESET button" three times.
3. Select any alarm (1 or 2) that has been set up in a group, press the
"RESET button" of 1 and wait for the connection after three "DI" sounds.
4. The new alarms’green led flashing three times slowly, the device is successfully
connected to 1.
5. Repeat the above steps to add more devices.
[Notes and Notices]
1. If there are many alarms to be added, please add them in batches( 8-9 pcs in one
batch)，otherwise, network failure due to the time exceeding one minute.
2. Maximum 30 devices in a group.
Exit the group
Press the "RESET button" twice quickly, after the green LED flashes twice, press and
hold the "RESET button" until the green light flashes quickly, meaning it has
successfully exited the group.
Installation and Test
For general places, when the space height is less than 6m, the alarm with a protection
area of 60m. The alarm shall be mounted on the ceiling.
1. Remove the ceiling mount.
2. Drill two holes with a spacing of 80mm on the ceiling with a suitable drill, and then
stick the included anchors in the holes and mount the ceiling install with both screws.
3. Install 2pcs AA batteries in the correct direction.
Note: If the positive and negative polarity of the battery is reversed, the alarm cannot
work normally and may damage the alarm.
4. Press the TEST / HUSH button, all paired smoke detectors will alarm and LED flash.
If not: Please check if the battery is installed correctly, the battery voltage is too low
(less than 2.6V ±0.1V) or smoke detectors not paired successfully.
5. After testing, simply screw the detector in the ceiling mount until you hear a "click".
