Conventional Beam Detector
Installation Guide
Step 3. Final Gain Adjustment
In this step, the detector will electronically adjust its internal gain
one final time. It is necessary to complete this step with the outer
housing installed since the housing will change the amount of light
received from the reflector.
1. Tighten the optics lock down screws so the optics are secure.
2. Install the outer housing of the detector. The housing is installed
by tightening four screws, one in each corner of the housing. The
screws are captivated in the plastic of the housing and cannot
fall out during assembly.
Note:
The housing contains a gasket seal that protects the detector
circuitry from corrosion and moisture sources. To ensure that the
gasket seal performs correctly it is necessary to fully tighten all four
of the screws that hold the outer housing in place.
3. Remove the protective film from the front surface of the outer housing.
4. To initiate the final electronic gain adjustment, the reset switch must be depressed. Once depressed the yellow
LED will begin to blink. This indicates that the detector is adjusting the electronic gain setting. Once complete,
the yellow LED will stop blinking and the green LED will begin blinking. This indicates that the gain adjustment
was successful.
Note:
Use caution not to block the line of sight between the detector and reflector in this step.
5. Install the outer aesthetic ring by snapping it onto the outer housing.
Note:
If the outer aesthetic ring has been painted ensure that the paint is completely dry before proceeding with
this step.
Step 4. Final Verification
This step is required to ensure the detector has been setup correctly and will detect smoke at the proper sensitivity
level.
1. With the detector functioning (indicated by the green LED blinking), completely block the reflector with an
opaque material. (Due to the high optical efficiency of the reflector, the selection of the opaque material used
to block the reflector is not critical. Acceptable materials include, but aren’t limited to, this manual or the
cardboard packaging inserts.) The detector should enter the trouble condition (indicated by the fault relay and
the yellow LED (see Appendix I). If the detector does not enter the trouble condition there is a problem with the
installation refer to the troubleshooting section in Appendix I for further assistance.
2. Complete a sensitivity test of the detector. Refer to the Sensitivity Testing section of this manual for the
appropriate procedure.
3. If the orange sticky paper was used to aid in the location of the reflector in the alignment mirror it should
be removed now. It is no longer necessary. Congratulations. You have completed the final installation and
alignment procedure.
