6.4. Exiting Alignment Mode.

Do not remove the detector from the wall during this action.

Using the mode switch (See fig. 4) select 'Operating 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, the Fault LED will illuminate and the panel will show a Fault. In this

case the alignment procedure must be repeated.

If the internal calibration check completes satisfactory, the AMBER LED will flash once every 10 seconds. The

panel will need to be reset. The Detector will be in normal operating 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.

7.2. Fault Test.

Cover the Prism(s) totally with a non-reflective material and confirm that the Detector indicates a fault condition

after approximately 10 seconds. The Amber LED on the Detector will flash, and the panel will show a Fault

condition. The fault condition will automatically reset after a period not greater than 2 seconds when the

obstruction is removed.
