System Sensor D4120 4 Wire Photoelectric Low-Flow Duct Smoke Detector The SYSTEM-SENSOR-D4120 4-wire photoelectric, low-flow, duct smoke detector senses smoke in the most challenging conditions, operating in airflow speeds of 100 to 4,000 feet per minute, temperatures of -4 degrees F to 158 degrees F, and a humidity range of 0 to 95 percent (non-condensing). A plug-in sensor head offers improved false alarm immunity and simple installation, testing, and maintenance. With its 2:1 sensor-to-power capability, the power board of the D4120 may be used to monitor a second sensor, D4S, simultaneously (i.e., supply and return side). As many as 50 InnovairFlex detectors can be interconnected. When one unit senses smoke, all interconnected detectors will switch their relays; only the detector sensing smoke will go into alarm, thus pinpointing the fire source. The D4120 features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork. The unit is equipped with a cover design isolates the sensor head from the low-flow feature for simple maintenance. Features: 4-Wire Photoelectric, integrated low-flow technology Air velocity rating from 100 ft/min to 4,000 ft/min (0.5 m/s to 20.32 m/sec) Versatile mounting options: square or rectangular configuration Plug-in sensor offers superb false alarm immunity and the latest sensor technology Broad ranges for operating temperature (-4 degreesF to 158 degreesF) and humidity (0% to 95% non-condensing) Patented sampling tube installs from front or back of the detector with no tools required Increased wiring space with a newly added 3/4-inch conduit knockout One easy-access Test/Reset button and improved LED status Patented interconnect feature for multi-fan shutdown New high contrast terminal designations Built-in short circuit protection from operator wiring errors Field selectable settings for configuring the detector Two DPDT Form-C relay contacts 24 VAC/DC or 120 VAC Backward compatibility with existing Innovair products, including remote accessories Technical Specifications: Rectangular Dimensions: 14.38 in (37 cm) Length; 5 in (12.74 cm) Width; 2.5 in (6.36 cm) Depth Square Dimensions: 7.75 in (19.7 cm) Length; 9 in (22.9 cm) Width; 2.5 in (6.35 cm) Depth Weight: 2.5 lbs (1.14 kg) Air Duct Velocity: 100 to 4000 ft/min (0.5 to 20.32 m/sec) Power Supply Voltage: 120 VAC, 50-60 Hz Reset Voltage: 10 VAC min Reset time: (with RTS151) .03 to 0.3 sec.
