Honeywell 997 - 360° Ceiling Mount PIR Motion Detector Reviews
Submitted on 09/28/2020 Alarm Grid
The Honeywell 997 is a hardwired ceiling-mount PIR motion detection sensor that looks downward with a 360-degree coverage area. The total coverage area for the sensor will depend on how high it is mounted. The higher you mount it, the larger the coverage area. However, you should not mount it too higher, as then it will be unable to detect the movement that occurs below. The recommended mounting height for the Honeywell 997 is between 8 and 12 feet high. At a mounting height of 11-feet, it has a coverage area of 36 feet in diameter. Remember that as a ceiling mount motion, it looks in a circular pattern, rather than scanning across the room. Overall, we think the Honeywell 997 is a good device, and we give it a rating of 5 Stars.
There are many things we like about the Honeywell 997. For one, it has a twist-off cover for easy removal. It has a Walk Test LED, which makes it easy to test the sensor. The sensor has a cover tamper to let the system know if someone tries to open it up. A selectable pulse count allows you to adjust device sensitivity. But there are also some minor downsides for the Honeywell 997. As you cannot easily adjust the height of your ceiling, you are basically unable to adjust the coverage area for the sensor. And if your ceiling is greater than 12 feet high, then you probably shouldn't use the Honeywell 997 in that area. As a wired sensor, you will need to run a wire from the sensor to the panel. This may be difficult if you are not used to wiring. Also keep in mind that the sensor will draw 17 mA of power from the panel. This is not a large amount of current, but it should still be considered in your load calculation. Fortunately, these downsides are quite minor, and they do not stop us from giving the Honeywell 997 a 5-Star rating.
Good: Twist-Off Cover, Walk Test LED, Cover Tamper
Bad: Coverage Area Determined by Ceiling Height, Requires Wiring, Draws Power
Bottom Line: 5 Stars
