WARNING: Disable the zone or system before applying power
to the beam detector to prevent unwanted 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 BEAM1224A/BEAM1224SA 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 procedures 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.
