A05-228-01 A Division of Pittway 3825 Ohio Avenue, St. Charles, IL 60174 1-800-SENSOR2 (736-7672), Fax 630-377-6495 http://www.systemsensor.com Features • Low standby current • Shielded electronics • Noise immunity provides stable communications • Compact, stylish design • Sensor plugs easily into base • Built-in tamper-resist feature • Sealed against dirt, insects, and back pressure • SEMS screws for easy wiring • Easy to use decade address switches • Built-in type ID System Sensor Intelligent Sensors offer features and performance that surpass conventional sensors. The sensitivity of models 1551B, 2551HR, and 2551THR can be “set” individually in the panel software. The sensors may be continuously monitored for changes in sensitivity and compensate for dirt, temperature, or humidity to maintain the set sensitivity. Model 5551R offers a rate-of-rise temperature response while the 5551B offers a fixed temperature response. Specifications – 2551HR, 2551THR Dimensions Height: 3.2 ″ (8.1 cm), detector in base (add .5 ″ [1.27 cm] for thermal) Diameter: 4.0 ″ (10.2 cm) installed in B501 base 6.1 ″ (15.5 cm) installed in B501B base Shipping Weight: 9.6 ounces (272 g) Temperature Range 2551HR: 32 ° to 120°F (0° to 49°C) 2551THR: 32 ° to 100°F (0° to 38°C) Humidity Range: 10% to 93% RH noncondensing Air Velocity Rating: 3,000 fpm Operating Voltage: 15–32 VDC peak, 6.5 mA current for visible LEDs latched on Standby Current: 230 µA Sensor (2551HR): Photoelectronic (scattering principle) Thermal Sensor (2551THR): 135 °F fixed temperature alarm Smoke Detector Spacing: On smooth ceilings (as defined in NFPA 72) spacing of 30 feet (900 sq. ft.) may be used as a guide. See NFPA 72 for more details on spacing requirements. APPROVED MSFM |
