System Sensor BEAM1224, BEAM1224S - Manual (Page 6)

PRE-ALIgNMENT ChECkLIST
• Ensure that both the detector and reflector are mounted securely to
stable surfaces.
• Ensure that all wiring is correct.
• Ensure that terminal blocks are fully seated into their receptacles on
the detector.
• Complete any wiring dressing to minimize movement to the detector
once the alignment procedure is completed.
• Ensure that the appropriate number of reflectors are used for the in-
stalled distance. Distances between 230 & 328 Feet (70 - 100m) require
additional reflectors (4 total). The BEAMLRK accessory should be used
in these cases.
• Ensure that the line of sight between the detector and reflector is clear
and that reflective objects are not too near. See mounting Instructions
for more details.
• Ensure that both the detector and reflector are mounted within their
operational parameters for off axis angles. See Mounting Instructions
for more details.
• Disable the zone or system to prevent unwanted alarms before apply-
ing power.
• Ensure power to the detector is “ON”.
You are now ready to begin the alignment procedure.
STEP 1. COARSE ALIgNMENT
Refer to Figures 11 and 12 for this step.
1. Ensure that both optics lock-down screws are loose (Figure 11).
2. Look through the alignment mirror and find the reflector (Figure 12). If
it is difficult to spot, use the orange adhesive-backed paper installed with
the reflector as a reference. Make sure there are no people or objects
obstructing your view of the reflector. This is also a good time to confirm
that there are no obstructions or reflective objects within 15” (38.1cm) of
the beam’s path.
3. Once you’ve located the reflector in the mirror, adjust the horizontal and
vertical alignment wheels (Figure 11) until the reflector is centered in
the mirror. The objective is to align the reflector with the hole in the
gunsight and the circle on the mirror. This step will take some practice.
Your eyes must shift focus between the reflector and alignment gunsight
in order to successfully complete step 3.
STEP 2. fINE ADjUSTMENT
Refer to figures 10 through 12 for this step.
1. Ensure that neither you nor any other objects are in the line of sight be-
tween the detector and the reflector.
NOTE: This detector has a built-in amplifier that will occasionally adjust its
gain, or detection sensitivity, throughout the alignment process. This will be
indicated by a “--“on the digital display. Do not disturb the detector while the
gain is auto-adjusting.
2. Depress the alignment switch once (Figure 10). Both the digital display
and yellow LED should turn on (Figure 11). The display should read
“--“ indicating an electronic gain adjustment. After a few moments, the
display should show a number. If the display reads “Lo”, confirm that
you’ve completed the steps in the pre-alignment checklist and repeat the
coarse alignment process. The display will continue to read “Lo” until
the detector receives enough light from the reflector to function properly.
3. With the display indicating a numeric value, begin adjusting the horizon-
tal adjustment wheel in the direction that increases the number on the
display. When the number starts decreasing, continue rotating the knob
3-4 revolutions past the peak value to confirm that you’ve truly reached
the peak. Once you have confirmed that the true peak was reached,
rotate the knob back until you reach the peak value again. Repeat this
process with the vertical adjustment knob.
NOTE: If a value of 90 is reached, the detector will display “--“, indicating that
it is auto-adjusting its gain. Once a numeric value returns on the display, you
can continue adjustment. The number displayed after the gain adjustment
will be much lower than 90 in order to make it easier for you to find the peak
value. The number only aids in alignment – it is not an indicator of signal
strength.
4. Repeat step 3, switching back and forth between the horizontal and ver-
tical adjustment knobs until you have achieved the peak value. Remem-
ber that the goal is not to reach a value near 90; rather, it is to reach a
peak whereby the numbers decrease with further rotation of either the
horizontal or vertical adjustment knob.
5. Once satisfied with the alignment, depress the alignment button. The
digital display will turn “OFF” and the yellow LED will remain “ON”.
This step must be performed or else the alignment procedure is void and
the information will be lost.
