Magnetic Contacts.
Plain white, standard surface mount, cater for four wires, but only use two just for trigger.
One set on one building, other on different system in another building.
After 3 years with no alarms, get false alarms "door", happens again, then again. No wind, no door movement.
2nd building about the same age alarm triggered "door"
Is it me, but as they have been working for years why now?
Does the magnet get weaker, do they degrade after so long or is it my method of mounting (even after all these years).
Do they have to be placed side by side screws facing outward, or can you have the one on the frame mount screws facing forward and the non wired magnet side mount screws facing inward towards wired side. During tests and years of service it has always worked. As the contacts are very nearly touching each other.
Again with the other setup, wired side is on the frame, mount screws facing forward and the magnet part still the same vertical and inline, but at a slight angle on the curved trim on the upvc door.
Any idea's, are there stronger, or more reliable contacts.
Many thanks.
