Reflective Beam
Smoke Detector
Description
Gamewell’s reflective beam smoke
detectors (72223-160 or 72223-330)
are a single infrared transceiver
and a reflective prism. The signal
generated in the transmitter
element and reflected by the prism
back to the receiver element is
analyzed for the presence of smoke.
The internal microprocessor deter-
mines an alarm condition when a
predetermined level is reached. The
system is designed to be mounted so that the beam will project between 1
foot (0.305 m) and 2 feet (0.61 m) below and parallel to the ceiling. Lateral
detection may be up to 30 feet (9.144 m) to either side of the beam, provid-
ing a maximum total area coverage of up to 19,800 square feet (60' x 330' or
18.288 m x 100 m).

Engineer’s Specifications
The projected beam type smoke detector shall be a four-wire 12/24 VDC
device to be used with UL-Listed, separately supplied, four-wire control
panels only. Unit shall be Listed to UL 268 and shall consist of an inte-
grated transmitter and receiver. The detector shall operate between a range
of 15 to 330 ft. (4.572 to 100 m). The temperature range of the beam shall
be –22°F to 131°F (–30°C to 55°C). The beam detector shall feature auto-
matic gain control which will compensate for gradual signal deterioration
from dirt accumulation on lenses. The unit shall include a wall-mounting
bracket. Testing shall be carried out using a calibrated test filter. The
projected beam type smoke detector shall be Gamewell model 72223-160
(160 ft./18.288 m) or 72223-330 (330 ft./100 m).

Listings and approvals below apply to the
Reflective Beam Smoke Detectors. In
some cases, certain modules may not be

listing may be in process. Consult factory
for latest listing status.
• UL Listed:
Smoke Detector Spacing
On smooth ceilings, up to 60 ft. (18.288 m) between projected beams and not
more than one-half that spacing between a projected beam and a sidewall.
Other spacing may be used depending on ceiling height, airflow characteris-
tics, and response requirements. See NFPA 72 for further information.
