Installation
It is recommended that the installation site be in the center area of the ceiling, with at least 60 cm distance from
wall or obstacles.
Do not locate the detector in the following locations:
Kitchen or Garage – Smoke from cooking or vehicle might cause false alarm.
Near a ventilating fan, florescent lamp or air-conditioning equipment – air drafts from them may affect the
sensitivity of the detector.
Near ceiling beams or over a cabinet – stagnant air in these areas may affect the sensitivity of the detector.
In the peak of an “
A
” frame type of ceiling.
Step 1. Use the mounting bracket as template to mark the two mounting holes. Drill holes in
mounting location and insert wall plugs if needed.
Step 2.
Screw the mounting bracket into marked location with the two hooks facing downward.
Step 3.
Locate the single line mark on the detector and line it up with one of the hook of the
bracket. Fit the Smoke Detector onto the hooks on the bracket, then rotate the detector
counter-clockwise to lock into place. The installation is now completed.
Testing the Smoke Detector
Press the Learn/Test button on the Smoke Detector to test if the Smoke Detector is functioning normally.
If the Smoke Detector functions normally, the LED will turn on briefly, and the Smoke Detector will sound a
2-tone beep.
If the buzzer sounds 3 times of 2-tone beep, which means the “
Optical Chamber
” on the Smoke Detector is
either dirty or out-of-order.
If the LED fails to light up and no beep is sounded, it means the Smoke Detector is either out-of-order or its
batteries are exhausted.
Supervisory Signal
After installation, the Smoke Detector will automatically transmit Supervisory Signals periodically to the
Control Panel at intervals of 30~50 minutes randomly.
If the Control Panel has not received the signal from the Smoke Detector for a preset period of time, the
Control Panel will consider the particular Smoke Detector out of order and react according to panel setting.
Smoke Detection
Once the concentration of the smoke exceeds the set threshold value, the Smoke Detector will transmit alarm
signal to the Control Panel and activates buzzer to sound continuous alarm for 10 seconds. The LED will flash
rapidly.
Once a Smoke Alarm Signal has been transmitted, the Smoke Detector will continue to perform follow-up
checks and send alarm signals every 2 minutes if the smoke concentration continues to exceed alarm
threshold. This 2-minute cycle will be repeated until the smoke concentration returns to normal. The alarm
can also be stopped manually by using the “
Alarm Silence
” function.
Alarm Silence
Once the alarm is sounding, pressing the Learn/ Test button will put the Smoke Detector into Alarm Silence
mode for 10 minutes and the alarm will be stopped.
During this 10-minute Alarm-Silence period, the LED will flash every second.
When the 10-minute period expires, the Smoke Detector will sound a 2-tone beep and then returns to normal
operation mode. If the Smoke concentration is still over alarm threshold value, the Smoke Detector will start
the alarm again.
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 Learn/Test button for 10 seconds until the LED starts to flash. The Smoke Detector will
sound 2 short beeps, and then follow the process described in calibration process in Learning/Getting Started
section to take the new reference value
Whenever the batteries are removed and reinserted, the Smoke Detector will also recalibrate according to
previous instruction.
