General
The System Sensor BEAM1224 and BEAM1224S are four-
wire conventional reflected beam smoke detectors. They are
uniquely suited for protecting open areas with high ceilings
where spot-type smoke detectors are difficult to install and
maintain. BEAM1224 and BEAM1224S are to be used with UL
Listed compatible fire alarm control panels only. Installation of
the single-ended reflective design is much quicker than a dual-
ended projected beam detector. Alignment is easily accom-
plished with an optical sight and a two-digit signal strength
meter incorporated into the beam detector. Listed for operation
from –22°F to 131°F, the BEAM1224 and BEAM1224S can be
used in open-area applications to provide early warning in
environments where temperature extremes exceed the design
limits for other types of smoke detection.
The BEAM1224 and BEAM1224S are a transmitter/receiver
unit and a reflector. When smoke enters the area between the
unit and the reflector, it causes a reduction in the signal
strength. When the smoke level (signal strength) reaches the
predetermined threshold, an alarm is activated. The detectors
have four standard sensitivity selections as well as two Accli-
mate® settings. When either Acclimate® setting is selected,
the detector will automatically adjust its sensitivity using
advanced software algorithms to select the optimum sensitivity
for the specific environment.
The BEAM1224S has an integral sensitivity test feature of a fil-
ter attached to a servomotor inside the detector optics. Activa-
tion of the RTS151 or RTS151KEY remote test station moves
the filter into the pathway of the light beam, testing the detec-
tor’s sensitivity. This sensitivity test feature allows the user to
quickly and easily meet the annual maintenance and test
requirements of NFPA 72, without physical access to the
detector.
NOTE: Unless otherwise specified, the term BEAM1224 is used in
this data sheet to refer to both the BEAM1224 and the
BEAM1224A (ULC-listed version). Likewise, BEAM1224S
includes BEAM1224SA.
Features
