IR-Tec LDT-700SI is a dual technology 2-pole, 120/277VAC ivory wall switch sensor designed to fit in a standard NEMA wall box. This state-of-the-art dual-tech wall switch sensor combines digital Passive Infrared (PIR) and High Frequency Doppler (HFD) sensing technologies into an aesthetically pleasing housing to provide second-to-none occupancy/vacancy sensing based lighting control for all applications. HFD is an advanced sensing technology which utilizes super high frequency radio waves (4~12GHz) to
detect the occupancy, similar to ultrasonic sensor, but without requiring the grid openings on the front.
The LDT-700S will turn ON the load automatically when it detects the presence of an occupant, and will turn OFF automatically if no motion is detected before the delay time elapses. For compliance of specific energy code, such as CA
Title 24, the LDT-700S series can be easily programmed as a Vacancy Sensor. In vacancy sensing mode, the sensor will only turn ON the load by pressing the push-button manually and will turn OFF the load automatically per the sensor time delay. The LDT-700S allows for the push-button operation to be programmed with different control modes.
The sensor comes with an ambient light sensor (ALS) to inhibit the lighting if ambient light levels are higher than required. The Accu-Set digital potentiometers make delay time (TIME) and ambient light level (LUX) settings fast, easy and accurate. Patent pending Hybrid-Switching technology allows the
sensor to switch on the load even with very high inrush current, such as multiple LED or CFL lights connected in parallel.
