What distance between the sensor and the magnet causes the alarm to trip?

I lined it up, opened the door. When the alarm went off, I took the backing off and stuck it permanently. It works perfectly. Someone opened my door one night and I heard the alarm from upstairs. The intruder left promptly. Also, it alerts when children leave or enter the house, or leave the door open.

Did u calibrate it to the propper wheel size? Is the magnet within one CM of the sensor? Does the digital display sit above the sensor with its back facing the sensor? Did you check the battery in both units?

I,m not sure but I expect there is an incompatibility between the electronics of the motion sensor and the relay coil. If the relay works properly using an on/off switch, it is likely that the motion sensor not the relay is at fault.

yes the sensor is a remote/wireless magnetic sensor. The magnet is a built-in portion of the sensor. There are instructions with you alarm system and also with this sensor that will provide info on how to enroll it with your alarm panel.

Remember it is a "motion detector" not a size detector. Might try aiming the sensor a bit higher than normal, but at some point you will defeat its purpose.

Yes, If it is pulled away from the magnet the (very loud) alarm will sound.

If you disassemble it, you can see what the sensor is like. It's just a spring fixed at the bottom on the printed circuit board, and the top is free. Around the top is a metal frame, when lock is moved, top of spring starts swaying and touches the frame, thus triggering the alarm sound. So if the sensor is not sensitive enough, you can decrease the gap between top spring and the frame, or make spring a little softer.

It will still work fine. In fact, you will only need to attach the sensor side since the magnet will cause it to stick to the door. Since the alarm only goes off when the door if open there will be minimal interference so long as you do not place the receiver directly behind where now open door is between the transmitter and receiver since the signal will now have to bounce around before being received.

I don't know but what I can say about that piece of junk is: It developed a problem after about a month Cobys warranty wanted me to ship it to them for service at my expense (which is normal) BUT they wanted me to send them money for the return ship to me. AIN"T GONNA HAPPEN! I sent it back to Amazon for refund and bought another brank thats been fine for, I think 1-1/2 to 2-1/2 years now. I'm sorry but I don't use it for an alarm so can't comment on that.

I have to actually turn the receiver in pretty close to the spokes, it's a lot closer than I expected it to need to be. I keep the receiver probably less than an inch from the magnet. Yeah, it has to be that close, kind of annoying.

Its got an automatic stop when it hits the bottom, so i disconnected that sensor, that way it will go out as far as you need.

While I usually mount these on the inside of a door (well, on the side that it opens towards) but I have also mounted it in the situation I think you are asking about. I have also used magnets from other sensors, like the ones from a house alarm unit, and it has worked just fine. So if you have limited space you should have success by using most other small magnet pieces designed for sensors like this. Remember that the sensor portion of this set can be mounted horizontally (turned 90° from the sample picture).

3 feet. but I have not found the system very reliable, I have 4 sensors and they often miss reporting

I would not expect a problem since the sensor detects magnetic variances, I would ensure that there is at least 10 feet between the sensor and the cattle guard and ensure that the transmitter is positioned so the guard is not in between it and your receiver.

Make certain the magnet is on one of the outside spokes and it should be as close to the sensor as indicated in the instructions when it passes the sensor.

U have different settings. I think hi n low. Different settings is wider circumference before alarm goes off. Don't remember actual numbers

It is a magnetic door alarm. You attach 1 side to the door, and the other to the door frame. When the connection is broken the device alarm sounds.
