Conventional Beam Detector
Installation Guide
PRODUCT DESCRIPTION
The FireSense SS-BEAM1224 is a conventional projected beam smoke sensor. It is uniquely suited for
protecting open areas with high ceilings where other methods of smoke detection are difficult to install and
maintain. Alignment is quickly accomplished via an optical sight and a 2-digit signal strength meter incorporated
into the product.
Listed for operation from -30ºC to 55ºC, the SS-BEAM1224 can be used in open area applications to provide early
warning in environments where temperature extremes exceed the capability of other types of smoke detection.
The SS-BEAM1224 consists of a transmitter/receiver unit at the head end and a reflector. When smoke enters the
area between the unit and the reflector, it causes a reduction in the signal and when the smoke level reaches the
predetermined threshold, an alarm is activated.
The SS-BEAM1224 has four standard sensitivity selections along with two Acclimate settings. When either of the
two Acclimate settings are selected the detector will automatically adjust its sensitivity using advanced software
algorithms to select the optimum sensitivity for the specific environment.

Installation Guide
PRODUCT DESCRIPTION
Installation/Alignment
The alignment 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.
Pre-Alignment Checklist
3 Ensure that both the detector and reflector are mounted securely to stable surfaces
3 Ensure that all wiring is correct
3 Ensure that terminal blocks are fully seated into their receptacles on the detector
3 Complete any wiring dressing to minimize movement to the detector once the alignment procedure is
completed
3 Ensure that the appropriate number of reflectors are used for the installed distance. Distances between
70 - 100m require additional reflectors (4 total). The BEAMLRK accessory should be used in these cases.
3 Ensure that the line of sight between the detector and reflector is clear and that reflective objects are not
too near.

3 Ensure that both the detector and reflector are mounted within their operational parameters for off axis
angles (see below)
3 Disable the zone or system to prevent unwanted alarms before applying power
3 Ensure power to the detector is “ON”
You are now ready to begin the alignment procedure.
Reflector Mounting Guidelines
Step 1. Coarse Alignment
Refer to Figures 2 and 3 for this step.
1. Ensure that both of the optics lock-down screws are loosened so that the optics will move freely.
2. Looking through the alignment mirror, at both the alignment sight and reflector simultaneously, locate the
position 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 coloured object on the wall near the
reflector to aid 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 centred 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 1-3 for this step.
In this step you will be fine-tuning the optics to the reflector. 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 different 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 must be set by the operator.
Periodically throughout the fine adjustment step the detector will need to re-adjust its “electronic amplifier gain”
setting. When this occurs it will be indicated by the dual digital readout as “- -”. When this occurs, cease any further
adjustment until the display again reads a number value.
1. Ensure that neither you nor any other objects are in the line of sight between the detector and the reflector.
2. Depress the Alignment switch once. Both the digital display and the yellow LED should turn on indicating
that alignment mode has been entered. The display should begin reading “- -” signifying an electronic gain
adjustment. After a few moments the display will indicate a numeric value near 20. If the display reads “Lo”
then the detector is not receiving enough light from the reflector. Go back and repeat the coarse alignment step
and verify that the proper number of reflectors is used for the installed distance.
Note: The display will continue to read “Lo” until the detector receives enough light from the reflector to continue
with the fine adjustment step.
Note: In alignment mode (indicated by the yellow LED and the numeric display) the sensitivity select and test
switches are disabled.
3. With the display reading a numeric value, begin adjusting the horizontal and vertical alignment knobs one at
a time in the direction that increases the numeric signal level on the display. Continue adjusting each axis one
at a time going back and forth between them until a peak value is indicated. If a value of 90 is achieved, the
detector will re-adjust the electronic gain once again. This will be indicated by a “- -” reading on the display.
When this happens halt any further adjustment until the display again reads a numeric value. This process may
occur more than once during the fine adjustment step.
Note: Each time the display reads a value of 90 or greater the detector will reduce the electronic gain. Each time
the display reads a value of 10 or less the detector will increase the electronic gain.
4. Once satisfied that it is not possible to achieve a higher reading on the display, depress the alignment switch
to complete the fine adjustment step. The digital display readout will turn “OFF” and the yellow LED will remain
“ON”.
Note: It may not be possible to achieve a value near 90 on the display during the last adjustment iteration. The
final value of the display will not likely be near 90. This is normal. It is due to the detector reducing its electronic
gain each time a value of 90 is achieved. When this occurs the detector resumes with less electronic gain than
previously when 90 was achieved. Less gain makes it more difficult to achieve higher values. Final values anywhere
between 20 and 90 are acceptable if no further increase can be achieved.
Note: The alignment procedure is not complete yet. At this time it is possible to set the sensitivity of the detector
using the sensitivity switch and digital display. See the Sensitivity Selection section of this manual for further
details.

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.

Sensitivity Selection
The detector has six sensitivity selections. Each of these selections is only acceptable over a specific distance
separation between the detector and the reflector per UL268. The chart below is used to determine which
selections are acceptable for your installed distance. The sensitivity of the detector can be set only when the
housing is removed and the detector is not in the fine adjustment step of the alignment mode, indicated by the
illumination of the dual digital display. To set the sensitivity depress the sensitivity button one time (see Figure
1). Once the switch is pressed the digital display will illuminate and read the current sensitivity setting in percent
obscuration. To change the sensitivity continue to depress the sensitivity switch until the desired setting is achieved.
The digital display will turn off automatically if no further switch presses occur.
In addition to the four standard sensitivity selections the detector has two Acclimate settings. When either of
these settings is chosen the detector will automatically adjust its sensitivity using advanced software algorithms to
select the optimum sensitivity for the environment. The sensitivity will be continuously adjusted within the ranges
specified in the chart below.

Sensitivity
Total obscuration can be converted to percent per foot,
assuming uniform smoke density for the entire length of the
beam. The chart on the right converts total obscuration to
percent per foot for all acceptable sensitivity settings.
Sensitivity Testing
Detectors must be tested after installation and following periodic maintenance. The sensitivity of the BEAM1224/
BEAM1224S may be tested with a calibrated Test Filter (Reflector Test Card) or the local test switch on the
transmitter/receiver unit.
Note: Before testing, notify the proper authorities that the smoke detector system is undergoing maintenance, and
therefore the system will be temporarily out of service. Disable the zone or system undergoing maintenance to
prevent unwanted alarms.
Note: Before testing the detector, check for the presence of the flashing green LED at the receiver, making sure not
to disturb or block the beam. If it does not flash and the detector is not in trouble or alarm, power has been lost to
the detector (check the wiring).
