Alarm Silence
•
When the Smoke Detector is alarming, pressing the Test button will put the Smoke Detector into Alarm Silence mode to
silence the alarm for 9 minutes. The buzzer will only stop sounding after the alarm has been activated for at least 1-minute.
If the button is pressed before alarm time reaches 1 minute, the Smoke Detector will wait until alarm time has reach 1 minute
before silencing the alarm.
•
During the 9-minute Alarm Silence period, the Red LED will flash once per second. The Smoke Detector will continue to monitor
smoke concentration during the alarm silence period:
•
After the 9-minute Alarm Silence period has expired, if the smoke concentration has dropped below alarm threshold, the Smoke
Detector will emit a 2-tone beep and return to normal operation without sounding alarm.
•
If smoke concentration still exceeds alarm threshold, the Smoke Detector will start alarming again.
•
If smoke concentration continues to rise during Alarm Silence period and exceeds a second alarm threshold,
the Smoke Detector will start alarming again. An alarm activated by exceeding the second alarm threshold could not be
silenced by pressing the test button.
Recalibration
As the operation condition of the Smoke Detector may vary after being installed for some time, you may wish to recalibrate the
Smoke Detector to take a new smoke detection threshold value and ensure optimal performance of the Smoke Detector. To do this:
•
Press and hold the Test Button for 10 seconds and release when the Smoke Detector emits 2 beeps. The device will sound another
beep after 5 seconds and begin calibration. The Red LED will flash every 2 seconds to indicate.
•
Calibration process lasts 1~9 minute.
•
When calibration is finished, the Smoke Detector will sound a two-tone beep. The Red LED will stop flashing to indicate
it has returned to normal mode.
•
If calibration fails, the Smoke Detector will beep continuously, and the Orange LED will flash every second.
Please remove the battery, press the Test Button twice to fully discharge, and then reinsert the batteries to restart Smoke Detector.
