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.
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 too 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 Fire•Lite reflected beam detectors to be installed at
separations between 230 and 328 feet (70 to 100 meters). At these distances,
four 8 inch×8 inch reflectors must be used to provide enough reflected infra-
red 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 Fire•Lite 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 Fire•Lite 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).
6500-MMK
The 6500-MMK provides a heavy-duty multi-mount bracket for installations
prone to building movement or vibration. It offers similar tilt and swivel flex-
ibility found on the BEAMMMK. (To mount the transmitter/receiver to the
6500-MMK, the surface mount kit, 6500-SMK, must be used).
6500-SMK
The 6500-SMK allows the transmitter/receiver to be mounted to the 6500-
MMK heavy duty multi-mount kit.
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.
RTS451/KEY
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 of
applicable codes and standards such as, NFPA 72, National Fire Alarm Code,
as well as directives of the Authority Having Jurisdiction (AHJ).
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.
