Beam Alignment - SECO-LARM ENFORCER E-964-Q660Q Manual

Beam Alignment Procedure
1. Remove the sensor cover and turn On the top and
bottom lasers of both the transmitter and receiver.
There are a total of four lasers.
2. Adjust the transmitter's sensor unit vertically and
horizontally until the red dot is centered on the
receiver and the receiver's signal LED turns Off.
3. Repeat step 2 for the receiver then turn Off the
lasers.
4. Look through the viewfinder on the transmitter's
lower sensor and adjust it vertically and horizontally
until the receiver is clearly seen in the viewfinder.
5. Repeat step 4 for the receiver.
6. Turn On the beam alignment buzzer DIP switch
(fig. 9). If the beams are not aligned the buzzer will
sound.
7. Cover the top sensor on the receiver with the
included template (as shown in fig. 10). Adjust the
horizontal angle of the receiver's lower sensor
vertically and horizontally until the buzzer stops
sounding. Repeat while covering the lower sensor
and adjusting the top sensor.
8. Turn the buzzer Off.
9. Turn On the beam strength Indicator DIP switch
(fig. 9). If the beams are not aligned, the indicator
will display little or no beam strength, see fig.12.
10. Cover the top sensor on the receiver. Adjust the
horizontal angle of the receiver's lower sensor
vertically and horizontally until the beam strength
indicator displays a strong signal. Repeat while
covering the lower sensor and adjusting the top
sensor.
11. Turn the beam strength indicator Off.
Fine Tuning
The most accurate way to align the transmitter and
receiver is to measure the voltage using the voltage
output jack (fig.13).
1. Set the range of a multimeter to 0~10VDC.
2. Insert the red probe into the (+) terminal and the
black probe into the (-) terminal.
3. Using Table 3, adjust the receiver's sensors
vertically and horizontally until the best possible
voltage output is achieved.
