REFLECTION DEVICE MODEL 6P150
In this model the reflection device is pro-
vided by a micromechanical reflector device
affixed to the opposite wall.
BOOMERANG SF 6P150 ASSEMBLY AND SETTING UP PROCEDURE
1 Fix the TRX mounting bracket and plug in the TRX device. Aim it roughly in the direction of the selected microme-
chanical reflector unit opposite.
2
Fix the reflector micromechanical unit on the opposite side and aim it roughly in the direction of the TRX
.
3 Connect the wires as in the wiring diagram in the INT8BA and the TRX. Switch on the system and rotate trimmer “A”
18 turns in a clockwise direction. The Yellow Led can be in one of three possible states: either flashing, or ON, or
OFF. The Led ON means the IR return light beam is too low; if the Led is flashing the IR reflected beam is too high ; if
it is OFF the IR light beam reflected is roughly acceptable. This condition could be a fault in this phase.
4
Align the TRX device using the adjustment knobs “V” and “H”. The required state at the end of this phase is with the
yellow led flashing.
5 Rotate the TRX using adjustment knob “H” in the horizontal plane to the right until the yellow led “F” stops flashing
and goes out. Counting the number of turns of the knob turn back to the left side turning and counting until the yellow
led stops flashing and goes out. During operation the Smoke red flashing led can light up in alarm mode. This is nor-
mal. Reset by removing the connector to the TRX for min. 3 seconds.
6
Divide the number of turns two and turn by that amount towards the middle. You have now found the centre of the IR
beam in the horizontal plane. Repeat the above procedure using knob “V” for finding the centre of the IR beam in ver-
tical plane. In this situation the yellow Led must be flashing and the trouble interface relay will also operate ON/OFF
intermittently. This state is essential in this phase.
7 Repeat the procedure in 6 above for the micromechanical reflection device at the opposite position finding the centre
of the two axes looking from the opposite side at TRX’s yellow led (E) i.e. ON-OFF-Flashing.
8 Now, for the micromechanical reflection device, cover the reflector with a piece of card or paper. Looking toward the
TRX unit, the yellow Led will flash without covering. When you cover the micromechanical reflection device the TRX
switches off the flashing yellow led and lights the ON light continuously. After removing the obstruction the yellow led
will flash again. If it does not, check whether there is any shiny reflecting surface along the IR path between the TRX
and reflector device.
9
When both devices are aligned and the yellow TRX device led is flashing, rotate the trimmer “A” anticlockwise until it
stops flashing and goes out, When the led switches off it means the IR strength is accepted by the TRX. Half turn the
trimmer “A” clockwise with the led OFF before replacing the front cover and the slot cup.
