System Sensor Model BEAM1224 is a four-wire conventional
reflected beam smoke detector, which is uniquely suited for
protecting open areas with high ceilings, where other methods of
smoke detection are difficult to install and maintain. It is to be used
with UL Listed compatible control panels only. An advantage of this
single-ended reflective design is that it is much easier to install than
the dual-ended projected beam detectors. Alignment is quickly
accomplished via an optical sight and a two-digit signal strength
meter incorporated into the product. Another advantage of the
BEAM1224 is that it is listed for operation in temperatures ranging
from –22°F to 131°F. This means it can be used in open areas to
provide early warning in environments where temperature extremes
may exceed the capability of other types of smoke detectors.
BEAM1224 consists of a transmitter/receiver unit and a reflector.
When smoke enters the area between the unit and the reflector,
the smoke causes a reduction in the signal. When the smoke level
reaches the predetermined threshold, an alarm is activated.
BEAM1224 has four standard sensitivity selections, along with two
Acclimate™ settings (adjustable sensitivity). When one of the two
Acclimate settings is selected, the detector will automatically adjust
its sensitivity using advanced software algorithms to choose the
optimum sensitivity for the specific environment.
BEAM1224S is also equipped with an integral sensitivity test feature,
which consists of a test filter attached to a servo motor inside the
detector optics. When the remote test station RTS451 /RTS151 is
used, the motor is activated and moves the filter into the pathway
of the light beam, to test the detector’s sensitivity. This integral
sensitivity test feature allows the user to quickly and easily meet the
S911 3017888 7260-1653:0168 2165 annual maintenance and test requirements of NFPA 72.
