Honeywell DT906 Posts

Hi DIYers! We are happy to announce that we have some new long-range motion sensor options available on our website. These long-range motions are good for long, narrow areas such as hallways. You now have more options in choosing the perfect motion sensor for your home or business.

The first new product we would like to discuss may seem relatively minor, but it actually opens up a whole new world of possibilities for motion detection. We are now pleased to offer the Optex FL-60N Long-Range Lens. This convenient device replaces the stock lens for an Optex WNX-40 Series Motion Sensor. Once the lens is added, the motion sensor will enjoy a long-range coverage area of 60 feet by 6 feet. It's very easy to swap out the old lens, and the process can be completed by any DIY user.

Alarm Grid offers four (4) different Optex WNX-40 Series Motion Detectors. We have an option available for nearly every wireless alarm panel that we carry. If you don't have one of these sensors yet, make sure you choose the correct model when purchasing. You need to make sure that the frequency the sensor uses for wireless communication is compatible with your security system.

The following motion sensors from our website are compatible with the Optex FL-60N:

• Optex WNX-402G (433 MHz for 2GIG Systems)
• Optex WNX-40DS (345 MHz for DSC Systems)
• Optex WNX-40HW (345 MHz for Honeywell Systems)
• Optex WNX-40IX (319.5 MHz for Interlogix Systems)

In addition to the Optex FL-60N Long-Range Lens, we now offer the complete Honeywell DT900-Series lineup of hardwired, long-range DUAL TEC motion sensors. Before, we only offered the Honeywell DT906. Now we offer the DT900, DT901, and DT907 long-range motion sensors as well. These are all hardwired motion sensors that connect directly with a hardwired alarm panel or a compatible wired to wireless converter. The motion sensor use these wired connections for both power and data transmissions.

If you're wondering how these four DT900-Series motion sensors differ, it is actually quite simple. Both the DT906 and the DT907 have the same selectable detection ranges. You can choose between a coverage area of 200 feet by 15 feet, or 120 feet by 10 feet. However, only the DT906 has an anti-masking feature. The DT907 does not. Meanwhile, with the DT900 and the DT901, you can choose between a coverage area of either 90 feet by 70 feet, or 50 feet by 40 feet. But in this case, the DT900 has anti-masking, while the DT901 lacks this feature. Other than that, these are mostly the same sensors.

If you have any questions about these new long-range motion sensor options, or if you want to find out if a long-range motion sensor is right for you, please reach out to us. The best way to contact us is to email support@alarmgrid.com. Our team will check your email as soon as possible and reply back as soon as we can. We look forward to hearing from you and helping you find the perfect motion sensor for your needs.

Hi DIYers! You may have heard the term "Dual Tec Motion Sensor" being tossed around at some point or another. The term refers to motion detecting sensors that use two forms of detection for picking up movement. Usually, these two methods are passive infrared sensing and microwave detection.

A common complaint with motion sensors is that they are known to cause false alarms when mounted improperly. This is usually caused by having the motion sensor placed near a window, a ceiling fan or an air vent. The motions that cause these false alarms are usually PIR-exclusive sensors that use only one method for detecting motion. Now, these sensors will generally work very well and won't cause any false alarms when mounted properly.

The reality is that most false alarms caused by motion sensors are the result of poor mounting. But having a second detection method for verification can go a long way towards preventing any system false alarms. Although proper mounting is still very important, you might be able to save yourself some major inconvenience by springing for a more-advanced motion detection sensor. This is where Dual Tec Motions can come into play.

Honeywell Dual Tec Motion Sensors use passive infrared (PIR) detection and microwave detection when looking for movement. In order for one of these devices to activate and alert the alarm control panel, both the PIR sensor and the microwave sensor must activate. Nothing will happen if only one part of the sensors is triggered. This can be very useful if a single technology sensor is prone to randomly activating due to local environmental sources. The name "Dual Tec" comes from the fact that the sensors use two technologies in detecting motion.

The PIR sensor in a Dual Tec Motion will work by looking for changes in infrared (IR) energy that occur with movement. Every person, animal and object gives off some amount of IR energy. If a large mass of IR energy from a person or large object moves within the field of view of the PIR sensor, then it will signal that motion is present. Meanwhile, the microwave sensor will send out continuous signals that are designed to bounce off of objects and return to the sensor at a consistent rate. If the signal pattern changes, then the sensor will assume that motion is present.

Although a PIR sensor can technically work by itself, a microwave motion sensor would cause too many false alarms on its own. This is because microwave signals can pass through objects and walls, and they could very easily detect movement that occurs outside the building. But the PIR sensor will not work through walls, so it will only detect motion that occurs from the inside.

However, pairing a PIR sensor with a microwave sensor in a Dual Tec Motion Sensor results in the perfect team. Even if the PIR sensor responds to flowing air or sunlight or some other local change in IR energy, the microwave sensor will keep it in check. Likewise, the PIR sensor will not respond to the outside movement that may trigger the microwave sensor. But both sensors will still respond very reliably to any real motion that is actually present in the building. And once that happens, it's game over for any intruders!

Honeywell offers Dual Tec Motion Sensors of all types. Their Dual Tec lineup includes wireless motion sensors like the Honeywell 5898, as well as wired motion sensors like the Honeywell DT8035. There's even a long range Dual Tec Motion, the Honeywell DT906, that is perfect for large commercial settings that require the highest level of protection possible. Honeywell has truly covered all their bases here!

You can get all of these great Honeywell Dual Tec Motion Detecting Sensors from the Alarm Grid website.
