| 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 determines 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, providing a maximum total area coverage of up to 19,800 square feet (60' x 330' or 18.288 m x 100 m). g2154phl.jpg Features * 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. * Calibrated obscuration test filters included. * Selectable alarm thresholds: 25%, 35%, 50%. * Microprocessor controlled. * Low current draw. * Selectable automatic reset. * Automatic gain control. * 12 VDC or 24 VDC operation. * Status LEDs. * 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 integrated 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 -22F to 131F (-30C to 55C). The beam detector shall feature automatic 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. * 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 characteristics, and response requirements. See NFPA 72 for further information.
