System Sensor will show its range of accessories designed to expand the versatility and usability of its InnovairFlex™ duct smoke detectors, says the company. This increased versatility and usability is said to enable installers and technicians to save time and money on installation, testing, and maintenance. One accessory is the new DST sampling tube (shown here). These plug-in sampling tubes install from the front or the back of the detector, without tools. Another new set of accessories is the RTS2 and RTS2-AOS multi-signaling devices.
