Description

The Honeywell DT7450C DUAL TEC Motion Detector is a hardwired motion sensor that utilizes both PIR and microwave detection technology. It is a Form C sensor, meaning it that it can be used with either Normally Open or Normally Closed wiring for added flexibility in the installation.

The reason that the DT7450C is referred to as a "dual-tech" motion sensor is because it uses both passive infrared (PIR) and microwave sensing capabilities. The PIR sensor works by detecting changes in infrared energy that occur with movement. The microwave sensor sends out continuous microwave signals and measures how these signals return to the sensor as they bounce off of other objects. Both the PIR and the microwave sensor of the DT7450C must be activated in order for an alarm to occur. This can be very helpful for reducing false alarms on the security system. Both the PIR and microwave sensors can be individually adjusted for sensitivity.

The DT7450C was specifically designed for commercial settings, and its max coverage area of 50 feet by 60 feet is perfectly suitable for larger rooms and spaces. The sensor must be mounted properly to achieve this maximum coverage area. The recommended mounting height for the sensor is 7.5 feet. The standard lens can allow be replaced with a long range lens that offers 8 tiers and a 50 feet by 10 feet coverage area. This long range lens does not come included with the sensor, and it must be purchased separately.

The DT7450C sensor features a Form C relay contact that is single pole double throw (SPDT). It uses advanced DualCore Signal Processing for more accurate detection and overall performance. Additionally, K-Band technology allows the sensor to better recognize individual people and objects and perform more effective shaping and signal recognition. Other features include uniform sensitivity optics, digital adaptive microwave thresholds, temperature compensation, digital fluorescent light filters, dual slope temperature compensation, a look down mirror, and a zero clearance back bug guard.

The Honeywell DT7450C is a wired dual-tech motion sensor that uses both PIR and microwave technology to detect movement. As a Form C sensor, it can utilize Normally Open (NO) or Normally Closed (NC) wiring. The sensor provides a maximum coverage area of 50 feet by 60 feet, making it great for covering larger rooms. You can even swap out the lens to adjust the coverage area. However, it is important to realize that the sensor is discontinued, and you are unlikely to find a new model. But don't be hesitant to grab a used model, especially with the strong build-quality of the sensor. Overall, we really like the Honeywell DT7450C, and we give it a 5-Star rating.

There are many positive aspects regarding the Honeywell DT7450C. The fact that this sensor is dual-tec is definitely a plus, as it helps to reduce false alarms. The sensor will only activate if both its PIR sensor and its microwave sensor are triggered. Being a Form C sensor that supports either NO or NC wiring can be a major convenience during installation. This gives the installer greater flexibility in setting up the sensor. Both the PIR sensor and the microwave sensor can be individually adjusted for sensitivity to meet the needs of the end user. The maximum coverage area of the sensor is quite large at 50 feet by 60 feet.

There are not many downsides for the Honeywell DT7450C. One issue is that a wire must be run from the sensor to the alarm panel. This may prove to be a difficult task if you are not used to wiring. But as a wired sensor, needing to run a wire is to be expected. There is also the consideration that the sensor will need to draw some power from the panel. It uses up to 35mA of power, so make sure to consider that in the load calculation. Lastly, the sensor is discontinued, so you are unlikely to find it new. Fortunately, these downsides are very minor, and they do not stop us from giving the Honeywell DT7450C a 5-Star rating.

Good: Dual-Tec, Form C, Sensitivity Adjustments, Large Coverage Area

Bad: Must be Wired, Draws Current, Discontinued

Bottom Line: 5 Stars
