| Description The 1109010 FDR100-EZ Addressable Reflective Beam Detector is developed for use in areas where point type detectors would be difficult to install and maintain. The FDR100-EZ has a detection ranges of up to 100 m. A transmitter and receiver are contained in one enclosure. The transmitter emits an invisible infrared beam, which is reflected back to the receiver, by a prism mounted directly opposite and in clear line of sight. The presence of smoke obscures the beam and reduces the signal strength detected at the receiver. Continuously Monitored The 1109010 FDR100-EZ Addressable Reflective Beam Detector incorporates continuous monitoring of both electrical and optical faults. If the infrared beam is obscured rapidly to a level above 90%, for approximately 10 seconds the condition is seen as a fault. Long-term degradation of signal strength is monitored and adjusted automatically. Installed under flat horizontal ceilings, a single unit provides satisfactory smoke detection up to 7.5 m on either side of the beam axis. For larger areas multi detector systems can be installed. The FDR100-EZ addressable detector is connected directly to the ZP3 loop wiring and is configured with it’s own address which the control panel poles every two seconds. Unique Alignment Alarm thresholds of 25%, 35% and 50% obscuration are selectable, making the detector suitable for a wide range of building environments. The fire output can be set to latch, only cancelled by resetting the device, or auto reset where the detector is reset automatically 5 seconds after the received infrared signal has recovered to a level above the alarm threshold. The detector and the reflecting prism are installed on opposite walls of the protected area, usually between 0.3 and 0.6 m below ceiling height. With unique alignment features, the equipment is easy to install, provides high stability and freedom from false alarms. |
