o To do this, release the 4 screws [L] (2 large ones on top,
2 small ones near the bottom).
o After making all connections gently reseat the sensor assembly
and put the 4 screws back.
 Attach the housing to the mounting bracket and secure it with the
two mounting bolts [J].
 Apply power to the system. The alignment LED [D] will turn red
since no reflector is detected.
 Place the reflector in line with the transmitter/receiver lens [C]
until the alignment LED [D] turns green. Mark the position of the
reflector and mount it in that location.
 Note: the lens can be aligned horizontally (± 25°) by rotating the
entire lens head (do not force) or vertically using the vertical
alignment bolt [F].
 Close the cover [H] with the 4 screws and slide the hood [A] in
place.
 Note: by closing the cover, the tamper switch [E] is pressed and
the tamper contact [6]/[7] is closed.
6. Operation
 When the beam between transmitter and receiver is broken, the
alignment LED [D] turns red and an alarm is triggered on the
output contacts until the beam is restored:
o [3] - [5]: open contact
o [4] - [5]: closed contact
 When the alignment LED [D] flashes red and green alternately an
alignment problem occurs. Open the cover and slowly adjust the
horizontal and/or vertical angle [F] of the lens [C].
 In case somebody opens the cover, the tamper switch [E] is
released and the tamper contact is closed:
o [6] – [7]: closed contact
7. Cleaning and Maintenance
 Make sure the cover and reflector are clean at all times.
 Remove dirt with a soft lightly moist lint-free cloth.
