3.
Setting the relay to NO/NC
3.1. The standard setting of the detector is NO. To change the
detector setting to NC, do the following.
3.2. Remove the two screws on the rear of the detector (Fig. 3)
and then remove the cover plate.
3.3. You see a jumper on the PCB. Plug the jumper in the other
pair of holes.
4. Installing the detector
4.1. On the outside of the base plate are two lines – one long
and one short.
4.2. Place the detector on the base plate so that the line on the
detector meets the short line on the base plate.
4.3. Press the detector lightly against the base plate and turn it
in a clockwise direction until the line on the detector is
opposite the long line on the base plate.
Test
1. If the detector is correctly connected to the power supply, the
green LED on the detector flashes every 3 to 5 seconds following
a delay of about 60 seconds. If the LED does not flash, either the
cabling is wrong or the detector is defective.
2. Use a test aerosol to test the detector.
2.1. Spray the test aerosol for at least 10 seconds into the
smoke chamber.
2.2. When sufficient aerosol has entered the chamber, the
detector triggers an alarm and the red LEDs light up
continuously.
2.3. Reset the smoke detector using a relay of the alarm panel
to remove the power from the detector or manually by
removing the detector from the base plate and replacing it
on the base plate after a view seconds.
Reset
After an alarm the smoke detector needs to be reset. This can be
done by the alarm panel or manually. Using the alarm panel the power
supply must be controlled by a relay. After an alarm you simply
deactivate the relay for a view seconds. Manual reset is done by
simply removing the smoke detector from its base plate and replacing
it after a view seconds.
