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 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
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).
BEAMHK
The BEAMHK allows the transmitter/receiver unit to oper-
ate in environments prone to the formation of condensa-
tion. 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 environ-
ments 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 conden-
sation 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
(BEAMLKR), 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, RTS451/KEY 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.
