We generally recommend mounting the motion sensor as follows:
- In the corner of a room. This gives the sensor the widest possible range of view so that it can cover the greatest possible area.
- At least 6 feet high, and no more than 8 feet high. Again, this height range promotes the widest field of view.
- The sensor must be mounted so that the LED has the correct vertical orientation. This will depend on the type of motion sensor that you are using:
60-639-95R - LED on Top
60-703-95 - LED on Top
60-511-01-95 - LED on Bottom
60-511-02-95 - LED on Bottom
- At a 90 degree angle to the floor. In other words, we recommend that you mount the sensor straight up and down, rather than angling it downwards. Angling it downwards can reduce the range of the motion sensor. Only mount the motion sensor at a downward angle if you are trying to cover a small area and wish to avoid even a small blind spot under the sensor itself; for example, a small foyer in front of an entry door, or a small utility/mudroom.
- If you own small animals that climb on furniture (for example, cats), we recommend that you try to mount the sensor away from bookcases or other tall items of furniture. While most of the motion sensors that we offer have features that greatly reduce the risk of animals setting off a motion detector, it is possible that if an animal passes close to the front lens of the motion sensor that it could set it off.
- We generally recommend that you mount the sensor so that the front lens does not face a window that looks out directly on a driveway or a road where there is the possibility of car headlights shining directly on the lens. This has been known to set off motion detectors on a few occasions.
- Do not mount the sensor at the end of a narrow area such as a hallway. The beams that the sensor uses fan out at a fairly wide angle from the lens. In a narrow, confined area such as a hallway, the beams tend to bounce off the walls and interfere with each other, thus reducing the range of the motion.
- If possible, do not mount the sensor so that warm air from a heating duct or vent can pass in front of it. If the heat is turned on in a cold room, the motion detector can pick up the sudden rise in temperature of the hot air coming in from the vent and set off an alarm.
If for whatever reason you cannot use the double-sided tape to mount the motion detector, there are knockouts on the back plate to use screws to mount the motion detector. To take off the back plate, simply press the depression on the top of the motion sensor and pull off the back plate.
Use the knockouts labeled: "Use with Animal Alley lens" to mount the motion detector with screws.
