Honeywell DT906

DUAL TEC Long-Range Commercial Motion Sensor w/ Anti-Mask

Average rating:

(based upon one review)

The DT906 is a DUAL TEC motion sensor that uses both PIR technology and microwave detection. The dual detection method helps to prevent false alarms. It is a long-range motion detector with a detection range of up to 200 feet. Anti-masking prevents tampering. Buy the DT906 from Alarm Grid.

Description

The DT906 is a feature-rich, long range, Dual-Tec (Microwave and Passive Infrared) motion detector with a selectable coverage area of 200 feet by 15 feet, or 120 feet by 10 feet. This motion offers PIR Anti-mask that sends a pulsing infrared beam out into the field of view every 8 seconds.

If the PIR is masked, the IR beam will be reflected back. After 2 consecutive bounce-backs, the unit will signal a trouble condition, the red and green LED’s will flash, and the normally closed “Mask Detect” circuit will open. In addition to anti-mask, the DT906 has a zero clearance bug-guard to keep the creepy-crawlers out.

The INFORMER® circuit, counts the activations on each technology, Microwave and PIR, and uses the resulting ratio to determine if each technology is working properly, and if they are adjusted properly. If the unit detects a problem, it will still be active, and will still activate the alarm relay if motion is detected. The unit performs the INFORMER® self-test upon power up, upon input from the installer, and every hour during normal operation. When a self-test error occurs, all three LED’s will flash, and the normally closed Trouble relay will be opened until the condition is resolved.

The motion also has a cover and mounting bracket tamper with a separate normally closed output. It has advanced temperature compensation technology, which adjusts every 30 seconds based on the ambient temperature in the room for better protection, as well as false alarm immunity.

The alarm relay is form C (Common, Normally Open, Normally Closed) with separate EOL terminals so you don’t have to solder resistors into the circuit. The alarm relay has a contact rating of up to 25VDC and 125mA. Power consumption is 50mA Max (at 12VDC).

Great Outdoor Motion Sensor!

The Honeywell DT906 is a long-range dual-tech hardwired motion sensor that utilizes both PIR and microwave detection technologies. Using dual methods for detecting motion helps prevent false alarms, as the system will not be alerted unless both sensors (PIR and microwave) are triggered. The sensor offers a long range coverage area of up to 200 feet by 15 feet. Overall, the Honeywell DT906 is a great sensor, but it does have some downsides to consider. We give it a 5 Star rating.

There are many positive aspects that help the Honeywell DT906 stand out. Being a dual-tech sensor is a huge plus, as it helps prevent false alarms. Users who may have had trouble with false alarms for motion sensors in the past may achieve great success by switching to a dual-tech device like the DT906. But also keep in mind that many false alarms on motion sensors are caused by poor mounting. The DT906 can still cause false alarms if it is mounted poorly or used in an undesirable location. But as a dual-tech motion, it is less likely to cause false alarms. Another benefit of the DT906 is that it features anti-masking technology. This is very good for letting the system know if someone tries to defeat the sensor by applying a substance to its lens. The DT906 has a great coverage range, as its detection area spans from up to 200 feet away. The device features a bug guard to keep out insect.

Despite all those positve aspects, the Honeywell DT906 does have some serious downsides to keep in mind. Its biggest downfall is that the sensor is very difficult to adjust. This isn't a huge surprise considering how powerful of a motion sensor it is. But the sensor is so difficult to adjust that Honeywell actually released their own guide specifically covering the process for adjusting and configuring this sensor. Needless to say though, if you're looking for a simple motion sensor that is quick and easy to set up, the DT906 is not for you. We must also say that the Honeywell DT906 features a rather ugly and unattractive design. The sensor is mostly used in commercial settings where design isn't as important. While you can certainly use the sensor in your home if you have a wired system, it may become a big eyesore when mounted.

The Honeywell DT906 is a powerful motion sensor that is great for situations where a long-range dual-tech sensor is needed. But you will want to keep its downsides in consideration. Still, we see enough positve aspects in the DT906 to give it 5 Stars.

Good: Dual-Tech, Anti-Masking, Great Coverage, Bug Guard

Bad: Extremely Hard to Adjust, Ugly & Unattractive

Bottom Line: 5 Stars

Are you planning to have this as a standalone light or are you tying it into a security system? Does the light you plan to use have the ability to be triggered by a normally closed loop?
I am designing an outdoor security light that incorporates motion detection. It detect motion of humans and vehicles around the light. What sensors would you recommend?
