System Sensor Innovair D2, 2-wire Photoelectric Duct Smoke Detector

The new System Sensor D2 is a direct replacement for the DH100LP. The D2 includes a 2151 sensor. Replacmeent 2151 sensors can be found here.

The RTS451 and RTS451KEY are compatible with the D2 with the installation of an accessory coil, DCOIL, sold separately.

Features

• Versatile mounting options in square or rectangular configuration with modular construction
• Plug-in sensor
• Superb false alarm immunity with the latest sensor technology
• Broader ranges for operating temperature (-4°F to 158°F) and humidity (0% to 95% non-condensing)
• Patented sampling tube installs from front or back of the detector with no tools required
• A cover tamper feature to indicate a trouble condition for removed or improperly installed sensor cover
• Increased wiring space with a newly added 3/4-inch conduit knock out

Description

The InnovairFlex D2 2-wire photoelectric duct smoke detectorfeatures a pivoting housing that fits various applications: both squareand rectangular footprints mount to round or rectangular duct work.This new duct smoke detector senses airflow speeds rangingfrom 100 to 4,000 feet per minute with proven System Sensorprecision. The enhancements built into this model improve falsealarm immunity (with plug-in sensor head); broaden operatingtemperature (-4°F to 158°F) and humidity (0 to 95 percent non-condensing)ranges; while simplifying installation and maintenance.These advance features can detect smoke even in the harshest ductapplications.

The new design provides more wiring space with an added 3/4-inch conduit knockout. Numbers and labels for terminal designations are consistent with previous Innovair models. The new sampling tube can be clicked into position with one smooth motion from either the front or the back of the detector.

The InnovairFlex D2 duct smoke detector has signals to indicate trouble and maintenance conditions. Additionally, a cover tamper feature is incorporated to indicate a trouble condition for removed or improperly installed sensor cover. An improved cover design, with an integrated the low-flow feature, isolates the sensor head from the low-flow technology for simple maintenance.

The InnovairFlex series is designed for greater flexibility and reliable smoke detection to simplify installation and maintenance. The new InnovairFlex product line is backward compatible to existing Innovair models, including remote test accessories.

WARNING: Duct smoke detectors have specific limitations.

DUCT SMOKE DETECTORS ARE:
NOT a substitute for an open area smoke detector,
NOT a substitute for early warning detection, and
NOT a replacement for a buildings regular fire detection system.

Refer to NFPA 72 and 90A for additional duct smoke detector application information.
