hi DRS Joe from alarm grid and today we're going to talk about why you're wired door or window contacts may have stopped working I have one of those right here and just to go over how these work this is the contact side this is the magnet side for this particular for this particular model the way this works is there's a magnetic switch inside of this unit when the magnet gets close to it it closes it telling the alarm system that the window or door is now closed when the magnet moves away from it the switch opens telling the alarm system that the door window is now open pretty simple but there's a whole bunch of reasons why these could stop working one of the more common reasons is that the magnet is simply installed in the wrong spot these contacts the read switch it the recommended installing place for the magnet is on the opposite side of the read switch and the read switch is only on one side of the contact so for this one as we have our terminals on this side the read switch is pointing on this side which means when we install it we want to put our magnet next to that read switch we had our magnet on the wrong side of the contact or anywhere else around it it may not work and you're gonna want to fix it anyways because it's not really secure installation another reason that these could stop working is perhaps the wire going back to the alarm system has become damaged this can happen from rodents or environmental issues maybe somebody who's doing some work in the house and they cut it a whole bunch of different reasons couldn't have that happen but if the wire is chomped from here back to the panel it's not going to work properly with your systems I do want to mention one particular distinction between wired contacts and wireless contacts and it's something that you can run into when you're installing them wired contacts usually you're going to know which side the contact point is on the contact point is where the read switch is activated when the magnet gets close to the contact it's going to be the opposite end of these terminals these terminals are where the wire connects to the contact so when you're mounting it looking at just the design of this one you're going to know that the magnet has to go on this side this may change from to contact but if you do check the installation manual you will see exactly where the read switch sits and where the magnet needs to get close to it I say this because on a wireless contact you don't have any of those terminals around the contact so you may not know at first glance where the read switch is on the device the reason that this is important is that if the magnet goes to an area where the read switch isn't located you're not going to close the contact and it's not going to work properly for you on a wireless contact many of them have little bumps as indicators where the read switch is on this car in particular I have two little indentations right here and that tells me that the magnet has to line up with these bumps when I install it to get it to close when it gets close to the magnet again if you have any questions about where the reed switches on a wireless contact check the installation manual and it will tell you where it is in the device it's a good thing to know if you're looking for it another important thing with all contacts is the gap spacing gap spacing has to do with how far away the magnet has to be to the contact to get the read switch to activate in the contact basically what this means is how close does this magnet have to get to this contact to get it to close so that the system thinks that this zone is closed this changes from manufacturer to manufacturer usually it's somewhere around a quarter of an inch but I can't say that for certain for anything because this changes from device to device and from manufacturer to manufacturer so again make sure that you check your installation manual for this if it is a concern if you're getting your magnet pretty close to the contact when you're mounting it you can rest assured that it's going to work just fine but again if you're on that edge or if you want to check to see what the gap spacing actually is definitely check out the installation manual and the information should be there as a final point of why the contact could stop working perhaps something in programming on the panel change if you went into your panel and you were editing some stuff and you accidentally edited the contact programming there's a chance that it's not going to work anymore which would make you think that the contact is broken when it's really just program that's the issue if you do have your system and you are managing it by yourself just check your installer guide or your installer manual and go through the programming steps to check the fields for the contacts to make sure that it's set up correctly if you do have your system monitored by an alarm company there's a good chance you could call them up and just say hey can you help me confirm that my programming from my contact is correct you do have some wired alarm contacts though that are giving you trouble feel free to give us a call at eight at
