The Honeywell DT907 DUAL TEC Long-Range Motion Sensor provides reliable and accurate motion detection for any indoor commercial environment. The sensor has a long, narrow coverage zone that can cover a maximum area of 200 feet by 15 feet. It uses both PIR and microwave detection technology.
The great thing about using a dual-tech motion detector is that it makes false alarms much less likely to occur. This is because the sensor will only activate and alert the system if both detection technologies are triggered. In other words, the PIR sensor and microwave sensor must both detect movement, or else no alert will be sent out. This helps ensure that the sensor only responds to true motion events. It will ignore potential false alarms that could affect a PIR-only sensor, such as flowing air or direct sunlight. The DT907 also offers three (3) microcontroller-based sensitivity modes to allow the user to adjust the device sensitivity to suit their needs. Remember to walk test the sensor after installing or adjusting the settings.
Self-diagnostic testing is another important feature for the DT907. This is done through its INFORMER® circuit. This lets the device check itself and make sure that it is operating properly. The sensor will keep count of every time its PIR sensor and/or its microwave sensor are activated. It will then compare the number of PIR activations to the number of microwave activations to make sure that everything is working the way it should. The DT907 performs a self-diagnostic test whenever it is powered on and once during every hour of regular operation. If it fails a test, you will see three (3) LED indication lights. The sensor will also display status lights when recalibration maintenance is needed. It is important to note that the DT907 does not offer an anti-mask feature. If you want anti-masking, you should get a Honeywell DT906 Motion Sensor instead.
Other features for the Honeywell DT907 include a tamper-resistant housing and a zero-clearance bug-guard. This helps make the sensor suitable for all indoor environments. You can use it to great success in warehouses, large retail centers, manufacturing locations, hospitals, schools and more. It also has a digital fluorescent light filter to prevent various lighting setups from interfering with the sensor. Users can choose between a sensor coverage area of 120 feet by 10 feet or a coverage area of 200 feet by 15 feet. This makes the DT907 suitable for long and narrow locations, such as hallways. Honeywell also offers the DT901, which has a max coverage area of 90 feet by 70 feet. There's also the DT900, which has the same maximum coverage area as the DT901, but with an added anti-mask feature.
The DT907 is a Form C hardwired motion sensor, meaning that it can be used with Normally Open (NO) or Normally Closed (NC) wiring configurations. It has separate EOL terminals, which eliminates the need to solder a resistor into the circuit. You should mount the motion sensor between 6 feet and 12 feet high. There is a top cover tamper switch, but no tamper switches for the bottom cover or the wall cover. Fortunately, there is a look down zone to detect any instances of someone trying to disable the sensor from below. Included with the device is a swivel mount bracket for installation. Max power consumption is 50mA at 12VDC. The alarm relay is Form C, with a max contact rating of 25VDC and 125mA. The sensor weighs three (3) pounds. Its dimensions are 8" x 6.5" x 6".
