WARNING:
Disable the zone or system before applying
power to the beam detector to prevent unwant-
ed alarms. When applying power to the beam
detector before the alignment procedure has
been completed the detector may enter alarm
or trouble.
Installation / Alignment
Reference Figures 10 through 14 for installation, alignment,
and maintenance.
The alignment of the BEAM1224/BEAM1224S is divided
into four steps: coarse alignment, fine adjustment, final
gain adjustment, and final verification. It is necessary for
all four steps to be executed properly to ensure proper
alignment of the product. If the detector and reflector
are mounted per Mounting Locations and Mounting
Instructions sections of this manual and the alignment pro-
cedures are executed properly, false alarms and nuisance
trouble signals will be minimized.
Pre-Alignment Checklist
• Insure that both the detector and reflector are mounted
securely to stable surfaces.
• Insure that all wiring is correct.
• Insure 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.
• Insure that the appropriate number of reflectors are
used for the installed distance. Distances between 230
& 328 Feet (70 - 100m) require additional reflectors (4
total). The BEAMLRK accessory should be used in these
cases.
• Insure 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.
• Insure 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 applying power.
• Insure 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. Insure that both of the optics lock-down screws are loos-
ened so that the optics will move freely.
2. Looking through the alignment mirror at both the align-
ment sight and reflector simultaneously locate the posi-
tion of the reflector in the optical sight. This step will
require some practice. It is necessary to train your eyes
to shift focus between the reflector and the mirror in
order to locate the reflector. If the distance between the
reflector and the detector is large it is helpful to place a
brightly colored object on the wall near the reflector to
aide in seeing the reflector in the alignment mirror.
3. Once the reflector has been located, begin to adjust both
the horizontal and vertical alignment knobs so that the
reflector becomes centered in the alignment mirror. Take
care in this step. If the optics are incorrectly aligned in
this step, it will not be possible to proceed with the fine
adjustment step.
Step 2. Fine Adjustment
Refer to figures 10 through 12 for this step.
In this step you will be fine-tuning the optics to the reflec-
tor. To provide feedback of the signal level coming from the
reflector the dual digital display readout will be used. Due
to the large distance range that the detector can operate
over it is necessary that the detector operate with many dif-
ferent settings of “electronic amplifier gain”. The detector
is capable of determining the appropriate gain setting and
then setting it itself via on-board processing algorithms.
There are no external gain settings on the detector that
