7251

Low-Profile Plug-in Intelligent Laser Smoke Detector Pinnacle™ model 7251 is an intelligent, laser-based photoelectric smoke detector featuring extensive on-board signal processing capabilities designed to improve smoke response. Features • Ultra-high-sensitivity capability • On-board drift compensation • Transient rejection algorithms • Environmental tracking • Wide sensitivity range • Rotary address switches • Analog communications • Sleek, low-profile design • Low standby current • Microprocessor design • Superior EMI protection Pinnacle features a patented smoke sensing chamber, designed to amplify signals from smoke but diminish stray internal reflections. By using a laser diode instead of a standard LED light source into the sensing chamber, Pinnacle is able to achieve sensitivities from 0.02 percent-per-foot to 2 percent-per-foot obscuration. The detectors’ extensive software processing includes multi-alert drift compensation, internal self diagnostics, and superior transient signal rejection algorithms to produce unprecedented stability at ultra high sensitivities over the complete temperature range. Because Pinnacle is base-compatible with all other 200 Series detectors, system designers can seamlessly mix it with other standard detection technologies thereby reducing overall cost. Unlike other high-sensitivity detectors, Pinnacle: • Can pinpoint identification of the fire location through addressability. • Experiences no delay in response time due to smoke dilution or smoke transportation time (as in aspirated systems). • Offers complete supervision of wiring and detector. Pinnacle is designed to protect valuable assets and operations where systems must remain online at all times. Many sensitive areas cannot tolerate even small amounts of smoke. Some ideal applications for Pinnacle include: • Telecommunications switching facilities • Cellular telephone infrastructure • Integrated circuit fabrication facilities • Computer rooms • Traffic control centers • Clean rooms Agency Listings Specifications Electrical Specifications Voltage Range Standby Current (max. avg.)
