General Description
System Sensor Model BEAM200A/BEAM200SA is a long range
projected beam smoke detector designed to provide open area
protection. It is to be used with ULC-listed compatible 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 signal. When the
obscuration reaches alarm thresholds (chosen at the transmitter/
receiver unit), the detector generates an alarm signal. Complete
blockage 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 periodically 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.
Special Applications
Due to the inherent capabilities of projected type beam
detectors they are often installed in locations where spottype 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 locations and large coverage area of
projected type beam detectors often the conditions above
can be addressed or minimized.
Some examples of applications for beam detectors might
include freezers, aircraft hangars, cold storage warehouses,
shipping warehouses, enclosed parking 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.
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. Note: The panel controls
the status of the red and green LEDs. The local reset button 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.
Trouble signals automatically reset upon removing the cause
of trouble. 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.
D400-74-00 2 I56-2542-00R
Before installing the transmitter/receiver unit or reflector
in these types of applications special consideration should
be given to insure proper operation of the beam detector.
The beam detector should not be installed in environments
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 8″×8″ 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 reflectors 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
necessary 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 transmitter/receiver unit
with the multi-mount kit (BEAMMMK).

Detector Placement
This section of the manual discusses the placement of projected
beam detectors. Though this information is based upon industry
expertise, it is intended to be used only as a technical guide.
Always comply with the requirements 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.
RTS451/KEYA
The remote test accessory, RTS451/KEYA 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.

NOTE: Projected beam smoke detectors should always
be mounted to stable 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 between 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

Figure 2. Spacing for smooth ceiling (top view):
In the case of peaked or sloped ceilings, codes may specify
spacing of detectors 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 between 12 and 18 inches (0.3 to 0.46m)
from the ceiling. In many cases, however, the location and
sensitivity of the detectors shall be the result of an engineering evaluation that includes the following: structural
features, size and shape of the room and bays, occupancy

Mounting Locations
Beam detectors require a stable mounting surface for
proper operation. A surface that moves, shifts, vibrates, or
warps over time will cause false alarm or trouble conditions. Initial selection of a proper mounting surface will
eliminate 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 surface that is not expected
to experience vibration or movement over time. DO NOT

Figure 5a. Reflector Mounting Guidelines
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 reflector 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

recessed junction 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
C0259-00
to the base using four screws. In order to mount the detector you must remove the outer housing first.
Mounting Considerations for Single Ended Beam
Detectors
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) may be used to provide greater angular
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
minimum 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.
adjustment of the transmitter/receiver unit. If the perpen-
dicular plane of the reflector cannot be mounted within 10°
of the optical line of sight then the multi-mount kit can be
used for the reflector. See BEAMMMK instructions.
