Manual Alignment
Manual alignment should only be used when
Automatic alignment has failed even after it
has been verified that the correct number of
reflectors have been installed and the correct
clearance around the beam path has been
given.
Perform targeting as previously described
Ensure Setting Switch 1 is in the right-hand
position, and move the Slide Switch to the
right-hand position
The green and amber LEDs may flash if the
detector needs to perform an initial power
adjustment
Once the LEDs have stopped flashing, use
the direction buttons to move the detector
in the up-down axis. First, use the direction
button in the down direction. Press the button
once, and wait to see what the LED indication
shows. If both amber and green LEDs flash,
the signal has not changed so no further
movement in that axis is needed.
If the amber LED flashes, the signal is smaller
and the detector is moved away from the
reflector. The next movement must be in
the opposite direction. Using the direction
buttons, move the detector again – this time
there should be a green flash.
If the green LED flashes, the signal is larger and
the detector is moving closer to the reflector.
The next movement must be in the same
direction. Keep moving the detector, waiting
for the LED flash each time. If the green
LED keeps flashing, keep going in the same
direction. If the amber and the green LED
flashes, then move onto the other axis. If the
amber LED flashes, move back in the opposite
direction once, then move onto the other axis.
Follow the same process with the direction
buttons, this time in the left-right axis. Start by
moving the left direction, and follow the same
LED flashes as described in the up-down axis.
Once the alignment has been completed on
both axis then move Setting Switch 1 to the
left-hand position. The right-hand green LED
will flash for 10s, the Fire and Fault relays will
go to normal state, and the Detector will flash
its status indicator green every 10 seconds.
You are now ready to select Alarm Thresholds
and Latching mode, and to test the Detector
to ensure it is operating and connected to the
Fire Control Panel correctly.
