Bosch D296 Projected Beam Smoke Detector 24V Long-Range Conventional Fire Detection

Bosch · Fire & Life Safety

Description  The Bosch D296 is a projected beam smoke detector designed for long-range smoke detection in large open indoor spaces. Manufactured by Bosch, it provides reliable fire detection over distances from 30 to 350 feet (9 to 107 m) using a conventional four-wire system. The detector is well suited for warehouses, atriums, manufacturing facilities, and other applications where spot smoke detectors may be impractical.     Technical Specifications  Condition New/Never Used Surplus Brand Bosch Category Fire Alarm Systems Part Number D296 Subcategory Projected Beam Smoke Detector Detector Type Projected Beam Smoke Detector System Type Conventional Four-Wire Operating Voltage 18 to 32 VDC (24 VDC Nominal) Standby Current Receiver: 45 mA; Transmitter: 20 mA Alarm Current Receiver: 70 mA Maximum Detection Range 30 to 350 ft (9 to 107 m) Sensitivity Settings 20%, 30%, 40%, 50%, 60%, 70% Beam Obscuration Alarm Contacts N/O, 1 A at 60 VDC Trouble Contacts N/C, 1 A at 60 VDC Operating Temperature -22°F to 130°F (-30°C to 54°C) Humidity Rating 0% to 95% RH, Non-Condensing Optical Adjustment ±90° Horizontal, ±10° Vertical Mounting 3.5 in., 4 in.
