Surplus from new install Comes with no original package or manual The Gamewell-FCI XP95-P analog addressable photoelec- tric sensor operates with the Gamewell-FCI, 600 Series and ILI95-E3 Series Fire Alarm Control Panels (FACPs). The photoelectric sensor digitally transmits its address and the chamber’s analog values to the FACP for analysis. The photoelectric sensor is distinguished by the clear status LED, which flashes red briefly when the device is polled and turns on continuously when the device is in alarm. Operation The XP95-P photoelectric sensor constantly monitors its sensing chamber and its internal electronics. The results are then reported along with the unit’s address through the integral communications electronics located in the sensor head. The XP95 photoelectric sensor utilizes a patented smoke chamber and infrared smoke sensing design. The infrared emitter generates a burst of light every second, or in response to direct interrogation. In clean air, the photo diode receives no light from the emitter because of the arrangement of the chamber. When smoke enters the chamber, it scatters light from the emitter onto the photo diode receptor in proportion to smoke char- acteristics and density. As the smoke content in the cham- ber increases, the signal from the photo diode receptor increases. This information is processed and conditioned by an on-board, advanced-technology ASIC and digitally transmitted to the FACP. Trouble and Alarm conditions of the XP95 sensors are actually determined at the control panel. The status infor- mation of each sensor is analyzed for off-normal conditions by the FACP. If the sensor reports a condition that matches its programmed trouble signature, the FACP will detect that the sensor is in trouble and will follow its programmed response sequence. If the status reported matches the alarm signature, the FACP will follow the programmed alarm response for the specific device in alarm. When a sensor is in alarm, the integral LED in the sensor’s housing will light continuously.
