Elkron SD200 Mode D'emploi page 3

DETECTING THE SMOKE
•
Once the concentration of the smoke exceeds the set threshold value, the Smoke Detector lights
up its LED to indicate it's sending the Smoke Alarm signal to the Control Panel. After the
transmission is completed, SD200 then activates its buzzer with LED flashing rapidly for 10
seconds for local warning.
•
After this 10-second local warning period, SD200 proceeds to perform a follow-up smoke check.
If the smoke concentration is found to be alarming still, SD200 will repeat another 10 seconds of
local warning with buzzer and rapid flashing LED.
•
SD200 will repeatedly perform follow-up checks until the smoke concentration is lower than the
set value, then the alarm will be stopped automatically or the alarm can be stopped manually by
using the "Alarm Silence" function.
•
Once a Smoke Alarm Signal has been transmitted, SD200 will continue to send alarm signals at
every 2 minutes when the smoke concentration continues to be higher than allowed.
This 2-minute cycle will be repeated until the smoke concentration is lower than the set value,
then the alarm will be stopped automatically or the alarm can be stopped manually by using the
"Alarm Silence" function.
ALARM SILENCE
•
Once the alarm is sounding, pressing the Test button will put the Smoke Detector into Alarm
Silence mode for 10 min. and the alarm will be stopped.
•
During this 10 min. Alarm Silence period, the LED will flash once per second.
•
After this 10 min. period is over, the Smoke Detector will sound a 2-tone beep and then returns to
normal operation mode. If the Smoke concentration is still over the set threshold value, the
Smoke Detector will sound the warning alarm again.
TAKING NEW REFERENCE VALUE
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 ensure the best use of the smoke detector. To do this,
•
Press 10 seconds on the TEST button and hold until the LED start to flash. The SD200 will sound
2 short beeps then follow the process described in calibration process to take the new reference
value.
•
Every time re-insert the batteries, the SD200 will also take the new reference value following the
warming and calibration process.
INSTALLATION NOTE
•
It is recommended that the installation site be in the center area of the ceiling.
•
Do not locate the detector in the following locations:
The Kitchen – Smoke from cooking might cause an unwanted 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.
