GENERAL DESCRIpTION
System Sensor Model BEAM1224A/BEAM1224SA is a long range projected
beam smoke detector designed to provide open area protection. It is to be used
with ULC-listed, separately supplied power (4-wire) control panels only. The
detector consists of a transmitter/receiver unit and a reflector. Smoke entering
the area between the transmitter/receiver and reflector causes a reduction in

Three LEDs on the detector indicate the current status: a red LED for alarm, a
yellow LED for trouble, and a blinking green LED for standby operation. The
alarm signal latches and can be reset by a momentary power interruption, by
using the remote reset input to the detector if using the remote test/reset sta-
tion, or with the local reset button located on the detector. The local reset but-
ton is accessible by removing the outer paintable trim ring. The yellow LED
will blink in specific patterns to provide a diagnostic aid when diagnosing the
cause of a trouble signal. It will also blink the amount of drift compensation
that has been used at the conclusion of the test. Trouble signals automati-
cally reset upon removing the cause of trouble. Red and yellow LEDs can be
remotely connected to the remote Alarm and Trouble outputs. These outputs
mimic the functions of the detector’s red and yellow LEDs. In addition to these
indicators, there is a dual digital display that reads 00 to 99. This display is
used to indicate the signal strength of the beam in alignment mode and to
indicate the sensitivity setting of the detector in percent obscuration when
setting the sensitivity of the detector. No additional equipment is needed for
alignment of the beam.
Each detector contains one Form A (normally open) contact for alarm signals
and one Form B (normally closed) contact for trouble signals. The trouble
contact will open if power is removed from the detector. Thus, an additional
EOL power supervision relay is not necessary. The trouble contacts from all
the beam detectors on one initiating circuit must be connected after the last
indicating device on the loop. This prevents a single beam detector in trouble
from disabling other initiating devices on the same loop.
SpECIAL AppLICATIONS
Due to the inherent capabilities of projected type beam detectors they are often
installed in locations where spot-type detection is impractical. Projected type
beam smoke detectors are ideally suited for environmental conditions that
might include high ceilings, dusty and dirty environments, or environments
that experience temperature extremes. Often these conditions present special
problems for the installation of spot-type detectors and even greater problems
for their proper maintenance. Due to the inherent flexibility of mounting loca-
tions and large coverage area of projected type beam detectors often the condi-
tions above can be addressed or minimized.
Some examples of applications for beam detectors might include freezers, air-
craft hangars, cold storage warehouses, shipping warehouses, enclosed park-
ing facilities, sporting arenas and stadiums, concert halls, barns, or stables.
Some of these environments might be considered to hostile for spot-type
smoke detectors. If the environment is considered to be hostile then the colder
alarm threshold settings should be used.
Before installing the transmitter/receiver unit or reflector in these types of
applications special consideration should be given to ensure proper operation
of the beam detector. The beam detector should not be installed in environ-
ments where there is no temperature control and condensation or icing is
likely. Condensation or icing of the reflector surface or the outer surface of
the transmitter/receiver unit will obscure the light beam resulting in a false
alarm. If elevated humidity levels and rapidly changing temperatures can be
expected then condensation will likely form and the application should not be
considered acceptable for the beam detector. The beam detector should not be
installed in locations where the transmitter/receiver unit, the reflector, or the
optical pathway between them may be exposed to outdoor conditions such as
rain, snow, sleet, or fog. These conditions will impair the proper operation of
the detector and must be avoided.
AppROvED ACCESSORIES
The following accessories can be purchased separately for use with this beam
detector.
BEAMLRK
The BEAMLRK allows System Sensor reflected beam detectors to be installed
at separations between 230 and 328 feet (70 to 100 meters). At these distances,
four 8inch×8inch reflectors must be used to provide enough reflected infrared
light. This kit includes 3 additional reflectors with new test scale legends. The
reflector included with the transmitter/receiver unit is the fourth reflector to
be used. This kit is not compatible with the multi-mount kit (BEAMMMK).
BEAMMMK
The BEAMMMK allows System Sensor reflected beam detectors and reflec-
tors to be mounted to either a vertical wall or the ceiling. The kit allows for
additional alignment range in cases where the detector and reflector cannot
be mounted within 10° of each other. The kit includes the hardware neces-
sary to mount either a single transmitter/receiver unit or a single reflector.
(To mount the transmitter/receiver the surface mount kit, BEAMSMK, must
also be used). If the transmitter/receiver and the reflector require additional
alignment range two kits are required. The kit is not compatible with the long-
range reflector kit (BEAMLRK).
BEAMSMK
The BEAMSMK allows System Sensor reflected beam detectors to be mounted
when surface wiring is used. This kit must be used when mounting the trans-
mitter/receiver unit with the multi-mount kit (BEAMMMK).
BEAMHK
The BEAMHK allows the transmitter/receiver unit to operate in environments
prone to the formation of condensation. Condensation forming on the beam
detector unit may result in trouble or false alarm conditions. BEAMHK will
lessen the likelihood of condensation by maintaining the unit at a temperature
that is slightly higher than the surrounding air. Please refer to the BEAMHK
installation manual for operation instructions.
BEAMHKR
The BEAMHKR allows the reflector to operate in environments prone to the
formation of condensation. Condensation forming on the reflector may result
in trouble or false alarm conditions. BEAMHKR will lessen the likelihood of
condensation by maintaining the reflector at a temperature that is slightly
higher than surrounding air. The kit requires a 24V power supply. When used
with the long-range reflector kit (BEAMLRK), it is necessary to purchase and
install four BEAMHKR kits. Please refer to the BEAMHKR installation manual
for operation instructions.
RTS451A/KEYA
The remote test accessory allows for the beam detector to be tested remotely.
The test accessory provides test and reset functions and green and red LED’s
that mimic the LED’s on the detector.

DETECTOR pLACEMENT
This section of the manual discusses the placement of projected beam detec-
tors. Though this information is based upon industry expertise, it is intended
to be used only as a technical guide. Always comply with the requirements
signal. When the obscuration reaches alarm thresholds (chosen at the trans-
mitter/receiver unit), the detector generates an alarm signal. Complete block-
age of the beam causes a trouble signal. Slow changes in obscuration due to
a build up of dirt or dust on the lens of the detector are compensated for by
a microcontroller that continuously monitors the signal strength and periodi-
cally updates the alarm and trouble thresholds. When the self-compensation
circuit reaches its limit, the detector generates a trouble signal, indicating the
need for service.

of applicable codes and standards such as, ULC S524, NFPA 72, National Fire
Alarm Code, as well as directives of the Authority Having Jurisdiction (AHJ).
For general information on the placement of detectors, read System Sensor’s
Projected Beam Detector Application Guide.
Projected beam detectors are usually located with their beams parallel to the
ceiling. However, they can be mounted vertically or at any angle to protect the
area involved. Since beam detectors sense the smoke buildup over a distance,
they are ideal for locations with high ceilings. They can also be mounted on a
wall or ceiling below the level of a spot type detector, reducing the effects of
air stratification. Some typical locations would include large areas with high
ceilings such as atriums, warehouses, and factories.
NOTE: Projected beam smoke detectors should always be mounted to sta-
ble mounting surfaces. See the MOUNTING LOCATION section for details.
Some fire codes specify spacing on a given center-to-center distance between
detectors under ideal conditions. This spacing is based on rooms with smooth
ceilings and no physical obstructions between the contents being protected
and the detectors. Moreover, they are also based on a maximum ceiling
height, and on the assumption that the value and the combustible nature of
the contents of the room being protected do not warrant greater protection or
closer spacing.
In a room with a smooth ceiling, detectors should be spaced horizontally be-
tween 30 and 60 feet (9.1 to 18.3m). One-half that spacing between the beam
and the sidewall may be used as a guide. See Figure 1. The beam detector
can be mounted with the transmitter/receiver on one wall and the reflector
on the opposite wall, or both suspended from the ceiling, or any wall/ceiling
combination. In the case of the ceiling mount, the distance from the end walls
should not exceed one-quarter of the selected spacing (7.5 ft. [2.3m] maxi-
mum if the spacing is 30 ft. [9.1m]). See Figure 2.

In the case of peaked or sloped ceilings, codes may specify spacing of detec-
tors by using horizontal spacing from the peak of the roof or ceiling. Figures
3 and 4 show the spacing for both the shed type and peaked type sloped
ceilings.
On smooth ceilings, beam smoke detectors should generally be mounted a
minimum of 12 inches (0.3m) from the ceiling or beneath structural obstruc-
tions such as joists, ducts, etc. See Figure 1. In many cases, however, the
location and sensitivity of the detectors shall be the result of an engineering
evaluation that includes the following: ceiling heights above 30 feet (9.1 m) -

tural features, size and shape of the room and bays, occupancy and uses of the
area, ceiling height, ceiling shape, surface and obstructions, ventilation, ambi-
ent environment, burning characteristics of the combustible materials present,
and the configuration of the contents in the area to be protected.

MOUNTING LOCATIONS
Beam detectors require a stable mounting surface for proper operation. A sur-
face that moves, shifts, vibrates, or warps over time will cause false alarm or
trouble conditions. Initial selection of a proper mounting surface will elimi-
nate false alarms and nuisance trouble signals.
Mount the detector on a stable mounting surface, such as brick, concrete,
a sturdy load-bearing wall, support column, structural beam, or other sur-
face that is not expected to experience vibration or movement over time. DO
NOT MOUNT the beam detector on corrugated metal walls, sheet metal walls,
external building sheathing, external siding, suspended ceilings, steel web
trusses, rafters, nonstructural beam, joists, or other such surfaces.
D400-85-00 3 I56-2541-005R

In cases where only one stable mounting surface as defined above can be
used, the transmitter/receiver unit should be mounted to the stable surface
and the reflector should be mounted to the less stable surface. The reflec-
tor has a much greater tolerance for the unstable mounting locations defined
above.
MOUNTING INSTRUCTIONS
The transmitter/receiver unit may be mounted over a recessed junction box.
The cavity behind the detector is then used for routing of the wiring from the
junction box to the terminal blocks on the detector. The transmitter/receiver
unit should be mounted to the wall such that unit covers the recessed junc-
tion box in the wall completely. If the junction box is not recessed then you
may use the surface mount kit (BEAMSMK). See the BEAMSMK installation
instructions for surface mounting instructions. The transmitter/receiver unit
can be mounted to the wall using the supplied drilling template (see Appendix
II). The detector base has 4 primary mounting keyholes, one in each corner of
the base. All four hole locations should be used to provide a secure mounting.
The outer housing of the beam detector is held to the base using four screws.
In order to mount the detector you must remove the outer housing first.
The reflector can be mounted to the wall using the supplied drilling template
see (Appendix III). The reflector has 4 mounting holes, one in each corner.
All four hole locations should be used to provide a secure mounting. The
reflector must be mounted such that it is within 10° in both the X and Y
planes of the transmitter/receiver unit. See Figure 5a. The reflector must also
be mounted such that plane of the reflector is perpendicular to the optical
line of sight to the transmitter/receiver unit. The maximum tolerance for non-
perpendicular mounting locations is 10°. See Figure 5b. If the reflector cannot
be mounted within 10° of the transmitter/receiver unit then the multi-mount
kit (BEAMMMK) or the heavy-duty multi-mount kit (6500-MMK) may be used
to provide greater angular adjustment of the transmitter/receiver unit. If the
perpendicular plane of the reflector cannot be mounted within 10° of the op-
tical line of sight then the multi-mount kit can be used for the reflector. See
BEAMMMK or 6500-MMK instructions.
To aid in locating the reflector in the alignment mirror at long distances a
bright orange sticky backed piece of paper is provided. Remove the protective
backing from the orange sticker. Temporarily affix the orange paper next to
the reflector using the sticky backing of the paper. The location of the sticky
paper is not critical. It may be placed anywhere near the reflector as long as it
not covering the reflective surface of the reflector. This sticky paper should be
removed once the installation is completed.

MOUNTING CONSIDERATIONS fOR SINGLE ENDED BEAM DETECTORS
There must be a permanent clear line of vision between the detector and the
reflector. Reflective objects must not be near the line of vision between the
detector and reflector. Reflective objects too near to the line of sight can reflect
the light beam from the transmitter to the receiver. If this occurs, the detector
will not be able to distinguish these reflections from those of the reflector and
the protected space will be compromised. Reflective objects should be a mini-
mum of 4 feet (1.2m) from the line of sight between the detector and reflector.
In cases where reflective objects cannot be avoided, the complete reflector
blockage test can be used to determine if the installation is acceptable. See
Testing and Maintenance Section of this manual.
Light sources of extreme intensity such as sunlight and halogen lamps, if di-
rected at the receiver, can cause a dramatic signal change resulting in fault
and alarm signals. To prevent this problem direct sunlight into the transmitter/
receiver unit should be avoided. There should be a minimum of 10° between
the pathway of the light source and detector and the line of sight between
detector and reflector.
Operation of the detector through panes of glass should be avoided. Since
single ended beam detectors operate on a reflection principle, a pane of glass
perpendicular to the line of sight between the detector and the reflector can
reflect the light beam from the transmitter to the receiver. If this occurs, the
detector will not be able to distinguish these reflections from those of the re-
flector and the protected space will be compromised.
Panes of glass will also absorb some of the light as it passes through it. This
absorption of light will reduce the acceptable installed distance between the
detector and the reflector.
In cases where operation through panes of glass cannot be avoided some spe-
cific installation practices can help to minimize the effects of the glass. These
practices include: avoid penetration of multiple panes of glass, position the
glass so that it is not perpendicular to the line of sight between the detector
and the reflector, (A minimum of 10° off perpendicular should be considered),
and make certain that the glass is smooth, clear and mounted securely. The
complete reflector blockage test can be used to determine if the installation is
acceptable. See Testing and Maintenance Section of this manual.
Where high ceilings (in excess of 30 feet or 9.1 meters) are present additional
beam smoke detectors mounted at multiple heights may be required to detect
smoke at lower levels. See the Detector Placement section in this installation
manual.
wIRING INSTALLATION GUIDELINES
Always install all wiring in compliance with the Canadian Electrical Code,
and/or the applicable local codes, and any special requirements of the lo-
cal authority having jurisdiction. Proper wire gauges and suitable means for
strain relief should be used. The conductors used to connect beam smoke
detectors to control panels and accessory devices should be color-coded to
reduce the likelihood of wiring errors. Improper connections can prevent a
system from responding properly in the event of a fire.
Installation wire used for the beam detector shall be no smaller than 22 AWG
(1.0 mm2). For best system performance, all wiring should be twisted pair and
installed in separate grounded conduit. Do NOT mix fire system wiring in the
same conduit as any other electrical wiring. Shielded cable may be used to
provide additional protection against electrical interference.
When installing the beam smoke detector in applications where the head unit
will be mounted to either a wall or the ceiling using the multi-mount kits
(BEAMMMK or 6500-MMK) flexible conduit will be used. The surface mount
kit (BEAMSMK or 6500-SMK) and multi-mount kits (BEAMMMK or 6500-
MMK) must be installed with the cable before wring the unit, according to the
instructions supplied with the kit.
When the detector has been mounted over a recessed junction box, all wiring
should be routed out of the box and behind the detector to the bottom of the
detector where the terminal blocks are located. When installing the wiring
in the junction box be sure to leave enough wire in the box to connect to the
terminal blocks. (Approximately 9" [23cm) of wire outside of the junction box
will be required for proper installation). All wiring to the detector is done via
pluggable terminal blocks. In order to properly make electrical connections
strip approximately 1/4" (6mm) of insulation from the end of the wire, sliding
the bare end of the wire under the clamping plate screw.

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 com-
pleted 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 verifi-
cation. 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
• 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 applying
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 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 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 adjust-
ment 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 reflector. To provide feed-
back of the signal level coming from the reflector the dual digital display read-
out 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 appro-
priate 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. Insure that neither you nor any other objects are in the line of sight be-
tween the detector and the reflector.
2. Depress the Alignment switch once. Both the digital display and the yel-
low LED should turn on indicating that alignment mode has been en-
tered. 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 in-
stalled 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 elec-
tronic 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 elec-
tronic 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.
D400-85-00 5 I56-2541-005R

NOTE: The alignment procedure is not complete yet.
At this time it is possible to set the sensitivity of the detector using the sen-
sitivity switch and digital display. See the Sensitivity Selection section of this
manual for further details.
STEp 3. fINAL GAIN ADjUSTMENT
Refer to Figure 13 for this step.
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 tight-
ening four screws, one in each corner of the housing. The screws are cap-
tivated in the plastic of the housing and cannot fall out during assembly.
3. Remove the protective film from the front surface of the outer housing.
NOTE: The housing contains a gasket seal that protects the detector cir-
cuitry 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.
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.)
See Figure 14. 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 instal-
lation refer to the troubleshooting section in Appendix I for further as-
sistance.
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 neces-
sary.
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 ULC and 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 illumina-
tion of the dual digital display. To set the sensitivity depress the sensitivity
button one time. See Figure 10. 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 Ac-
climate settings. When either of these settings is chosen the detector will au-
tomatically adjust its sensitivity using advanced software algorithms to select
the optimum sensitivity for the environment. The sensitivity will be continu-
ously adjusted within the ranges specified in the chart above.
SENSITIvITy
Total obscuration can be converted to percent per foot, assuming uniform
smoke density for the entire length of the beam. The chart below converts
total obscuration to percent per foot for all acceptable sensitivity settings.

SENSITIvITy TESTING
NOTE: Before testing, notify the proper authorities that the smoke detector
system is undergoing maintenance, and therefore the system will be tempo-
rarily out of service. Disable the zone or system undergoing maintenance to
prevent unwanted alarms.
Detectors must be tested after installation and following periodic maintenance.
The sensitivity of the BEAM1224A/BEAM1224SA may be tested as follows:
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).
A. Calibrated Test Filter
The sensitivity of the detector can be tested using an opaque material to cover
the reflector by an amount indicated by the graduated scale on the reflector.
(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 in-
clude, but aren’t limited to, this manual or the cardboard packaging inserts.)
REfER TO fIGURE 14 fOR ThIS pROCEDURE.
1. Verify the sensitivity setting of the detector in % obscuration. See the
Sensitivity Selection section of this manual for sensitivity determination
if sensitivity is unknown.
2. Place the blocking material over the reflector, lining it up with the
graduated marks that are 10 less than the detector’s setting in percent
obscuration. The detector should not alarm or fault. Keep the material in
place for a minimum of 1 minute.
3. Place the blocking material over the reflector lining it up with the
graduated marks that are 10 more than the detectors setting in percent
obscuration. The detector should enter alarm within 1 minute.

4. The detector can be reset with the reset switch on the detector unit, re-
mote reset, or momentarily interrupting power.
5. Notify the proper authorities that the system is back on line.

If the detector fails this test several steps should be taken to determine if the
detector is faulty or simply needs to be re-adjusted before returning the unit.
These steps include:
1. Verify all wiring connections and appropriate power is applied to the
detector.
2. Verify that the optical line of sight is free from obstructions and reflective
objects.
3. Apply the maintenance procedure in this manual. Repeat the test proce-
dure. If the detector still fails the test procedure proceed with step 4.
4. Repeat the alignment procedure in this manual. If the alignment proce-
dure is successful repeat the test procedure. If the detector still fails the
test it should be returned.
B. Test Switch
The detector can be tested using the local test switch on the transmitter/re-
ceiver unit or remotely using the remote test station.
The remote test station can be used with the BEAM1224A/BEAM1224SA beam
smoke detector. Follow instructions included with the test station for proper
use. See Figure 8 (Remote Test Station) for wiring diagram.
The BEAM1224SA is equipped with an integral sensitivity test feature that
consists of a calibrated test filter attached to a servo motor inside the detector
optics. When a test is initiated using the remote test station or local test switch
the test filter is moved in the pathway of the light beam. The on-board micro-
processor then determines if the proper level of signal reduction is received
at the receiver. If the proper level of signal reduction is received the detector
will enter alarm. If the proper level of signal reduction was not achieved, indi-
cating that the sensitivity of the detector is out of tolerance, the detector will
enter the trouble condition.
Always perform a complete reflector blockage test as in step 4 of the Instal-
lation/Alignment procedure to ensure that the pathway between the detector
and reflector is clear.
NOTE: For the BEAM1224A this test does not satisfy the requirements of
NFPA72 and/or ULC for periodic maintenance and sensitivity verification of
beam type detectors. For the BEAM1224SA this test in conjunction with the
complete reflector blockage test (see step 4 of the Installation/Alignment pro-
cedure in this manual) does satisfy the requirements of NFPA72 and/or ULC
for periodic maintenance and sensitivity verification of beam type detectors.
If the detector fails this test several steps should be taken to determine if the
detector is faulty or simply needs to be re-adjusted before returning the unit
for repair. These steps include:
1. Verify all wiring connections and appropriate power is applied to the
detector.
2. Verify that the optical line of sight is free from obstructions and reflective
objects.
3. Apply the maintenance procedure in this manual. Repeat the test proce-
dure. If the detector still fails the test procedure proceed with step 4.
4. Repeat the alignment procedure in this manual. If the alignment proce-
dure is successful repeat the test procedure. If the detector still fails the
test it should be returned.
MAINTENANCE
NOTE: Before cleaning the detector, 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.
1. Carefully clean the outer housing lens face. A damp soft cloth with a mild
soap may be used. Avoid products with solvents or ammonia.
2. Carefully clean the reflector. A damp soft cloth with a mild soap may be
used. Avoid products with solvents or ammonia.
3. Notify the proper authorities that the system is back on line.
pAINTING
The outer aesthetic ring may be painted using a spray or brush type paint of
appropriate type. See specification section of this manual for paint types.
NOTE: never paint the flat lens surface of the outer housing.
SpECIAL NOTE REGARDING SMOkE DETECTOR GUARDS
Smoke detectors are not to be used with detector guards unless the combina-
tion has been evaluated and found suitable for that purpose.
