Features
Smoke Detection
The Smoke Detector will be activated whenever the smoke concentration exceeds the detection
threshold. After activation, the Red LED will flash quickly and the Smoke Detector will transmit
alarm signal and raise alarm with its built in buzzer for 8 seconds. The alarm sound will repeat in
pattern of 2-second alarm and 1-second pause.
The Smoke Detector will check smoke concentration every 8 seconds, if the smoke
concentration still exceeds detection threshold after 8 seconds, the buzzer will continue to
sound alarm and the LED will continue to flash.
If the smoke concentration remains above the detection threshold, the Smoke Detector will
continue to send the alarm signal every 2 minutes.
If the smoke concentration drops below detection threshold, the Smoke Detector will stop
alarming immediately, a restore signal will be transmitted if no alarm is activated again for 160
seconds.
Alarm Silence
When the Smoke Detector is alarming, you can press the Function button once on Smoke
Detector to transmit a cancel signal and enter Alarm Silence mode for 10 minutes
Under Alarm Silence mode, the Smoke Detector will not sound alarm; the LED Indicator will
flash every second to indicate it is under Alarm Silence mode.
After 10 minutes, if the smoke concentration still exceeds detection threshold, the Smoke
Detector will raise alarm and send alarm signal again.
Recalibration
The Smoke Detector will calibrate its sensor every time when power is applied to ensure optimal
smoke sensitivity. After installation, the operation condition of the Smoke Detector may vary after
some time, which may affect its smoke detection function and requires recalibration. There are two
ways to recalibrate the Smoke Detector: auto calibration and manual calibration.
Auto Calibration:
After power up, the Smoke Detector will perform auto-calibration after 4 hours.
After the first auto-calibration, the Smoke Detector will perform auto calibration every month.
During the auto-calibration process, the Smoke Detector will not emit any sound.
If auto-calibration fails the LED will flash rapidly and the Smoke Detector will send a calibration
fail signal to the ZigBee Network coordinator. To stop the LED from flashing, remove and reload
the batteries or start a new calibration process manually. If the manual calibration fails again,
Smoke Detector will emit continuous beeps. To stop the beeping sound and the flashing LED,
remove and reload the batteries.
When Smoke Detector auto calibration fails, the smoke alarm function will still work normally
using the threshold value taken from the last successful calibration.
Manual Calibration:
Manual calibration can be performed any time as desired:
1. Press and hold the function button for 20 seconds.
2. The Smoke Detector will emit 2 short beeps at after 10 seconds and 3 short beeps after 20
seconds. Keep holding the function button and release until you hear the 3 short beeps after 20
seconds.
3. The Smoke Detector will enter calibration process. The LED Indicator will flash every 2 seconds.
4. After the Smoke Detector finishes recalibration, it will emit two quick beeps to indicate. The LED
will turn off.
5. If calibration process fails, Smoke Detector will emit alarm sound. Please remove and reinsert
battery to restart process again.
Battery and Low Battery Detection
The battery used varies according to Smoke Detector model number.
Model Number Battery
SD-16-ZBS 2 AAAlkaline 1.5V Batteries
SD-16SL-ZBS 1 CR123A 3V Lithium Battery
The Smoke Detector feature Low Battery Detection function. When the battery voltage is low,
the Smoke Detector will transmit Low Battery signal to the coordinator in ZigBee network.
If batteries are not changed after low battery, the Smoke Detector will stop all function when
batteries are exhausted and flash both LEDs every 4 seconds to indicate failure.
