Description The Honeywell DT7435 is a DUAL TEC® motion detector that combines passive infrared (PIR) and microwave technology to provide the best detection possible. Honeywell was the first security manufacturer to combine both technologies in a single motion detector and they trademarked the name DUAL TEC (DT). However, just like with all great technological innovations, nearly every security manufacturer quickly saw the advantage of a dual technology motion detector and therefore there are many imitations of the DT Series motion detectors available today. By combining the PIR technology with microwave detection, DUAL TEC motion detectors are much less likely to trigger a false alarm. The DT7435 can detect motion by sensing a change in the ambient temperature of a room using the PIR technology and can also detect movement by transmitting energy out into the room and sensing a change in the frequency of the energy received back at the device using the microwave technology. PIR motion detectors are prone to false alarms when there are lights or heaters in the room that may rapidly change temperature. Microwave motion detectors are prone to false alarms because the microwave energy can “see” through walls and therefore trigger an alarm when there is movement outside of the protected area. As PIR and microwave motion detectors are both susceptible to false alarms for different reasons, a DUAL TEC motion detector that requires both technologies to go off together is the best way to reduce false alarms
