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 consid-
ered 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 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 appli-
cation 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 detec-
tors 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 detec-
tors 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 com-
patible with the long-range reflector kit (BEAMLRK).
BEAMSMK
D400-73-00
The BEAMSMK allows System Sensor reflected beam detec-
tors 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).
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.

Detector Placement

This section of the manual discusses the placement of projected
beam d etectors. T hough t his i nformation i s b ased u pon i ndustry
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 mount-
ed vertically or at any angle to protect the area involved.
Since beam detectors sense the smoke buildup over a dis-
tance, 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 stratifica-
tion. Some typical locations would include large areas with
high ceilings such as atriums, warehouses, and factories.
