BD-SS and BDT-SS Features Single-Ended, Reflected-Type, Addressable Beam Smoke Detector with SmartScan™ • Transmitter/receiver built into same unit. • Six user-selectable sensitivity levels. • 16' to 328' (use BEAMLRK beyond 230') protection range. • Removable plug-in terminal blocks. • Digital display — no special tools required. Description The Gamewell BD-SS and BDT-SS are intelligent, addressable projected beam smoke detectors with SmartScan™ protocol. They are uniquely suited for protecting open areas with high and sloping ceilings, and wide-open areas, where spotBD-SS with reflective plate (top); type smoke detectors are difficult to and with BEAMMMK install and maintain. Ideal applications are atriums, cathedral ceilings, aircraft hangers, warehouses, sporting arenas, concert halls, and enclosed parking facilities. Installation of the single-ended reflective design is much quicker than a dualended projected beam detector. Alignment is easily accomplished 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 BD-SS and BDT-SS are usable in open area applications where temperature extremes exceed the design limits of other types of smoke detection. The BD-SS and BDT-SS 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 Acclimate™ settings. When either Acclimate™ setting is selected, the detector’s advanced software algorithms automatically adjust to the optimum sensitivity for the specific environment. The protection range is 16 to 328 feet and there are built-in isolators for Style 7 operation. The BDT-SS has an integral sensitivity test feature of a filter attached to a servomotor inside the detector optics. Activation of the RTS451 remote test station moves the filter into the pathway of the light beam, testing the detector’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. Sensitivity Selection The detector has six sensitivity selections. Each of these selections is only acceptable over a specific distance separation between the detector and the reflector per UL 268. The chart below determines which selections are acceptable for your installed distance. The sensitivity of the detector can be set only when the housing is removed and the detector is not in the fine adjustment step of the alignment mode, indicated by the illumination of the dual digital display. To set the sensitivity, depress the sensitivity button one time. See Switch Locations diagram.

Listings Listings and approvals below apply to the basic BD-SS and BDT-SS 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: file S1195. • FM approved. • MEA approved: file 269-04-E. • CSFM approved: file 7260-1288:171. Specifications digital display will illuminate and read the current sensitivity setting in percent obscuration. To change the sensitivity, continue to depress the sensitivity switch until the desired setting is achieved. The digital display will turn off automatically if no further switch presses occur.

Adjustment angle ±10° horizontal and vertical. Note that the optics move independently of the unit. Sensitivity (6 levels) 6985sens.tbl Sensitivity Setting Acceptable DISTANCE Display between Reading detector and reflector (ft) Operational Specifications • Level 1 — 25%. • Level 2 — 30%. In addition to the four standard sensitivity selections, the detector has two Acclimate™ settings. When either Acclimate™ setting is chosen, the detector will automatically adjust its sensitivity using advanced software algorithms to select the optimum sensitivity for the environment. The sensitivity will be continuously adjusted within the ranges specified in the chart above. Total obscuration can be converted to percent per foot, assuming uniform smoke density for the entire length of the beam. The chart below converts total obscuration percent per foot for all acceptable sensitivity settings. • Level 3 — 40%. • Level 4 — 50%. • Acclimate™ Level 5 — 30% to 50%. • Acclimate™ Level 6 — 40% to 50%.
