Press Fit Magnetic Contact

Recommended Posts

Hi.

 

I'm not much of an alarm guy but, I am trying to help a client out by cleaning up another installer's problem. I don't even want to know why this is the way it is... but anyway.

 

Does anyone see a problem with swapping out this contact with a 3/8" press fit magnetic contact?

I want to put the contact in the jamb above this hinge. you can see the surface mount around the corner right there...

Thanks for the info.

 

Yep, odd location for sure. I'm thinking I can clean up the finish quite a bit.

I've used the recessed magnet in the door above the door knobs, not the hines. placement above the door knob ensures a quick trigger. whenever I have to install it at the hinge I use the ball pressure type switch to trigger. it installs in the jamb unseen.....you cn easily put one in here since the wire is there. the ball types need a 1/2 hole so fishing it is not a issue. repair the expert dry wall work and you'll see nothing of a switch as it will be hidden in the jamb.

 

also, are you using and EOL resistors? most "decent" panels can handle them and any professional install should use them. I install the EOL resistors anywhere along the wire path but NEVER in or near the panel itself. EOL is a specific design feature that prevents shorting or sniping of the alarm wire itself. I have seen alarm switches cut and/or jumpered by employees so that they can enter the area without setting off the alarm. always train the user to call in a bad zone and get it repaired immediately if it does not work properly.

 

also take a look at gsm radio's for your monitoring station comm..........works great. basically is a cell phone path vice a tekephone connection................way better and reliable.

Cant say the same for here .. GSM is down here more than it is up, I even stopped using my cell alltogether as I got fed up .. land line is about as best as you get for phones down here, which doesnt say much as that has its own problems too .. we use Radio as Primary though when the client requires it.

Hi rory,

 

I'm not sure where the magnet is. I'm thinking he installed the switch and realized it wasn't going to work so didn't bother putting the magnet on the door?

 

Hi VST,

 

I was actually thinking of using a ball switch but was concerned about using it on the hinge side. The switches I am seeing have a flange that sits on the surface of the jamb and the door looks like it shuts completely flush on the hinge side. Wouldn't I have to inset the flange of the switch? It seemed like extra work compared to the mag switch.

 

I do like the idea of having a bigger switch hole for fishing the wire. I know they make larger press fit magnetic contacts too. Problem is I only have a couple of the 3/8" press fit on the truck. But I guess I should just order up a few switches. The job doesn't have to be completed today or anything. It's been like this for months.

 

Also I used "alarm" in the first post for brevity. It's an alarm contact but it actually triggers an event for those nursing call station devices. It's in a dentist office and each procedure area has a call station and when no one is at the receptionist desk they can hit a button on the receptionist's call station that will chime the other stations every time the front door is opened.

 

I do have a question about the GSM radios used for monitoring... Do any US carriers have special rates for this setup? The cheapest regular voice plans seem to be in the 30 to 40 dollar a month range. Meanwhile an RJ31X costs 4 bucks and you can just use an existing phone line. Are you using GSM all the time or just higher end security installs?

don't go thru the phone company.......use the alarm monitor company

 

I use Security Central and they sell me the gsm modules and provide the connection in a all in one price.

 

gsm connectivity needs to be tested prior to install to ensure that it connects with a tower/service. I use get the gsm on battery and test different locations and then I install it where it is best. There are also different antenna's available, including a 25ft. wire that allows you to run a antenna up the side of a structure............imroves the signal........

 

good luck

 

 

oh, yes you have to recess that ball switch but the overall appearance and profession appeal is worth the look of a magnet thingie.......they look crapy to me. just pencil the area and then use a special wood tool to carve it out. takes a whopp'n 5 minutes.

I under stand that but tell that to the guy thats breaking in to your house. Last time I checked we all have jobs because people don't follow the laws!!!!! If I was a criminal I would have one.

 

LOL I know where that magnet is!!!! It's on the floor in pieces every time someone opens the door. I would use a 3/4" plunger, quick easy, fix.

I've got some ball switches ordered up. I think I'll go that route if it will make me look like a pro.

 

I'll post some pictures if I don't jack it up too bad.

I can't wait to order one so I can go to the movies again.

 

I am sorry. I misunderstood. I did not realize that you were talking about a criminal.

 

I guess it depends on the target (your customer [or your own installation]).

It depends on the crook. If they cut the land line then yes they can Jam a radio signal.

 

Now would the panel still send out a signal once the jammer has been turned off, or has left the area?

 

This would rule out spur of the moment teenagers, and I would assume this would rule out street level drug addicts with an on the spur crime.

 

Now you have me paranoid as I have different codes to the alarm given to the maid, butler, maintenance guy, gardner, and the inlaw who stays in the pool house. Now I am wondering if this is an inside job as the crook only has to turn off the alarm with a code.

 

What do I do, what do I do???

This company took over the beeper infrastructure of towers, and satellites, and converted it to a wireless alarm communications system.

This is great for spec houses, or construction trailers where the phone/cable voip services have not been connected.

If it was me knowing how alarms work I would cut the phones and jam the cell then unplug and disconnect the battery. I have to think like a criminal to install alarm systems.

 

To prevent jamming I would put the Cell unit in a different location then the panel and use a trigger input on the cell with a spare pair of wires on the phone feed. If someone cuts the phone wire that will trigger the cell to send a code to central station regardless of what happens with the panel and hopefully before he can find it to jam it. But if they have one that can jam 200' game over.

 

Also keep in mind most panels can be programed to turn on the bell output if the phone is cut when the system is armed.

ok smartie...................out of 10 houses, which is gsm? phone line? none? CCTV? fake dog? ect.?

 

you name a system and I can beat it too..............nothing is fool proof.

 

The nice thing about gsm is that is provides a level of protection. not 100%, but good enough to improve the chances of early warning and/or arrests.

 

There is a good reason why all my neighbor's have been hit and I have not? maybe it's that dome camera's all over my property? PTZ's with with IR? possibly that sign that says "protected by alarm system"? maybe my dog? and I'm gone more than I am here. and yes, I've answered my door with my glock inhand.

 

ups loves me I never have to sign for it because....................

I seen it......................I liked it. But, have I ever seen anybody this educated or sofisticated try something like this? That senerio is slightly 1 in a million?

 

I could "try" to sell to this type of client but in reality the real money is closer to the ground for me...and more rewarding.

 

I hear ya but I don't see ya
