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. If this fails, which would be
due to bad alignment or either electrical or optical noise, the power level will try to compensate. If, after 60
seconds, the power level is still not correct, a Fault will be signalled to the control panel. The alignment
procedure must be repeated.
If the internal calibration check completes satisfactory, the Detector will enter its normal running mode.
7. System Testing.
After successful installation and alignment the System will require testing for both alarm and fault conditions.
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.
The Detector will indicate a fire within 10 seconds by illuminating the Red LED and activating the panel.
7.2. Fault Test.
Cover the Prism totally with a non-reflective material and confirm that the Detector signals to the control panel a
fault condition after approximately 10 seconds. When the prism is uncovered, the fault condition will
automatically reset after a period of 10 seconds when the obstruction is removed.
