Features

Reflective Beam

• Models for ranges of:

15 to 160 ft. (4.572 to 48.768 m)

160 to 330 ft. (48.768 to 100 m)

• Easy alignment.

Smoke Detector

• Calibrated obscuration test filters

included.

Description

Gamewell’s reflective beam smoke

detectors (72223-160 or 72223-330)

are a single infrared transceiver

• Selectable alarm thresholds: 25%, 35%,

50%.

• Microprocessor controlled.

• Low current draw.

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

• Selectable automatic reset.

• Automatic gain control.

• 12 VDC or 24 VDC operation.

• Status LEDs.

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).

• Separate trouble contacts.

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

Listings and approvals below apply to the

Reflective Beam Smoke Detectors. In

some cases, certain modules may not be

listed by certain approval agencies, or

listing may be in process. Consult factory

for latest listing status.

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.
