 The System Sensor BEAM1224 Series 4-wire projected beam smoke detector is uniquely suited to sense smoke in open areas with high ceilings where spot-type detectors are difficult to install and maintain. It is suitable for use with any UL® Listed fire alarm control panel providing a 15-32 VDC power source.
 The single-ended reflective design offers a simpler instal lation than the traditional transmitter and receiver types of beam detectors.

The InnovairFlex D4120 4-wire photoelectric duct smokedetector features a pivoting housing that fits both square andrectangular footprints and mounts to round or rectangular ductwork.This unit senses smoke in the most challenging conditions, operatingin airflow speeds of 100 to 4,000 feet per minute, temperaturesof –4°F to 158°F, and a humidity range of 0 to 95 percent (noncondensing).A plug-in sensor head offers improved false alarmimmunity and simple installation, testing, and maintenance. Animproved cover design isolates the sensor head from the low-flowfeature for simple maintenance.
