background image

transmits a signal to the control panel. After 

the transmission is completed, the smoke 

detector then activates its local built-in 

buzzer with the LED flashing. It will check the 

smoke concentration every 10 seconds, and 

should it be over the threshold it will continue 

the local siren warning. 

Once below the threshold, the smoke 

detector will stop sounding and resume 

standby. Alternatively the user can stop the 

alarm by: 

1)  Pressing the Test button on the smoke 

detector will silence the detector’s built-in 

siren for 10 minute (not the control panel). 

The LED will continue to flash if smoke still 

exceeds the threshold. After 10 minutes 

the siren will resume sounding if the smoke 

concentration is still too high.

2)  Disarm the system to stop the fire event 

on the control panel.

Recalibration of Smoke Detector

As the operation condition of the smoke 

detector may vary after being installed for 

some time, you may wish to take a new 

reference value to recalibrate the smoke 

detector. To do this:

Press and hold the TEST button for 10 

seconds until the LED starts to flash. The 

detector will sound 2 short beeps then 

start the recalibration which may take up to 

20 minutes. The smoke detector will also 

recalibrate itself after battery changes.
