Photoelectric integrated low flow technology Air velocity rating from 100 ft min to 4,000 ft min m s to 20.32 m sec Versatile mounting options square or rectangular configuration Cover integrated smoke test port Plug in sensor offers the latest sensor technology Broad ranges for operating temperature to 158 and 0 to 95 non condensing Patented sampling tube installs from the front or back of the with no tools required Increased wiring space with an added conduit knockout One easy access Test Reset button Patented interconnect feature for multi fan shutdown High contrast terminal designations and wiring diagram label on of power side cover make wiring easy Built in short circuit protection from operator wiring errors Two DPDT Form C relay contacts 24 VAC DC or 240 VAC Backward compatibility with existing products remote accessories Listings DUCTSD240 4 wire photoelectric duct smoke detector a pivoting housing that ts both square and rectangular and mounts to round or rectangular ductwork This unit smoke in the most challenging conditions operating in ow speeds of 100 to 4,000 feet per minute temperatures of 158 and a humidity range of 0 to 95 percent non condensing plug in sensor head offers simple installation and maintenance cover integrated smoke test port enables easy testing and housing provides ample wiring space a conduit and built in short circuit protection to prevent damage sensitive components during installation High contrast terminal make wiring easy As many as 30 DUCTSD240 can be interconnected When one unit senses smoke all detectors will switch their relays only the detector smoke will go into alarm thus pinpointing the alarm location easy access Test Reset button and smoke test port makes it to test the unit with the cover on The power board has an that can be used to indicate the status of the sensor Standby Trouble and Alarm The DUCTSD240 product line is with previous System Sensor models including remote accessories Duct smoke detectors are NOT a substitute for open smoke detectors NOT a substitute for early warning detection a replacement for a building regular re detection system to NFPA 72 and 90A

Interconnect Notes When using the interconnect feature all interconnected units must be powered using the same independent supply Polarity must be maintained throughout the interconnect wiring Connect the INT terminal on unit 1 to the INT terminal on unit 2 and so Similarly connect the INT AUX terminal on unit 1 to the INT AUX terminal on unit 2 and so on Up to 30 DUCTSD240 units may be interconnected NOTE Alarm can be reset only at the initiating device and not at the interconnected devices Sensor provides system exibility with a variety of accessories including two remote test stations and several different means of and audible system annunciation As with our duct smoke detectors all duct smoke detector accessories are UL listed UL S4011 UL S2522 UL S4011 UL S2522 UL S4011
