6.4. Exiting Alignment Mode.
Do not remove the detector from the wall during this action.
Using the mode switch (See fig. 4) select Run Mode (Switch will be in the down position).
On exiting alignment mode the Detector will perform an internal calibration check, this can take up to 60
seconds. If this fails which would be due to bad alignment or either electrical or optical noise, the detector
will indicate a Trouble condition. In this case the alignment procedure must be repeated. This could also
occur during power up after loss of power.
If the internal calibration check completes satisfactory the detector will be in normal running mode.
7. System Testing.
After successful installation and alignment the System will require testing for both Alarm and Trouble
conditions. This is to verify the functionality of the detector.
7.1. Alarm (smoke) Test.
Taking note of the threshold selected during installation (default 35%).
Select obscuration mark on filter to correspond with the Detector Alarm threshold (see fig. 3).
Place the filter over the receiver optics (Top of Detector Head
−
opposite end to the status indication
LED’s) at the correct obscuration value determined by the threshold selected. I.e. if a threshold of 35%
has been selected position the filter just past the 35% obscuration value on the filter (see fig 3.).
Take care not to cover the transmitter optics.
