This product helped me get the job done, and my glass breaks all got placed in the right spot. If you are on your own, and need some installation help, this site has great resources. But this glass break simulator does an amazing job of making sensor installation a snap.

I'm a DIYer, and I haven't gotten signed up with the AlarmNet service yet. Once I do I'm pretty sure this communicator is going to be awesome, doing exactly what I need it to do. Install was simple, and once I get things up and running, I'll come back and let you know for sure how it works.

I have never owned such an amazing keypad. I attached it to my vista panels along, installed some of the neat apps they have, and am absolutely loving the functionality. I do not have weather turned on (I have a iphone, so I don't need it on my Tuxedo) so I'm not sure about Joe65's problem, but everything else makes this worth it.

So turns out you can't use Total Connect 2.0 unless your Vista is a certain version. I had to buy this unit just to get the upgrade chip that is included. Now I have to try and sell my extra IGSMV on ebay but at least I have TC2!

Installation was super easy. Instructions are for the majority straight forward and it's pretty user friendly. L5100PK suits my needs. Highly recommended as a low-cost alarm system.

I have two Tuxedo Touch units installed this past March. Both are hard wired via Ethernet to my router and both worked flawlessly for about four months. Then I started noticing on both units the weather display function was erratic working sometimes and others showing “connection error” in the display. The other internet functions work ok. After two weeks of erratic operation, the weather function stopped working entirely. I contacted my alarm provider tech support and was told that Honeywell is aware of the problem and is working on a fix. So I waited. It’s now been 45 days since the weather function ceased working and Honeywell will not provide a date when they expect to have the problem resolved. I was told the problem is with Honeywell and there is nothing I can do. Now my tech support has gone silent on the issue. This unit is not recommended until Honeywell restores the weather display function.

i ordered the 5100 for myself as soon as it was available,read the instructions;did the wiring & all the other stuff --- LOVE THIS SYSTEM--- some family,friends & neighbors like it too. Have been asked to give advice for home security system. My answer is Lynx 5100 & "Honeywell LT-CABLE - LYNX Touch Power Supply Cable" Helped install one with a friend --- SIMPLE FAST EASY

Man Honeywell finally got it right with the 5811. I've never liked how the 5816s are so boxy so I've tried almost all of the smaller sensors. Problem is those sensors dont have the same wirelss range as the 5816. It's been a struggle to decide between a sensor that looks better or one that loses its connection from time to time. Now that they have the 5811, I swapped all my sensors out to these super thin sensors and I never have wireless range issues!

I used the 5816 contacts on every door leading into my house. I have a front door, garage side door, 2 sets of french doors in the back and a set of french doors in me and my wife's room. Alarm Grid had me put the contact on one french door and the magnet on the other door so I only needed to use 1 5816 for each set so that was cool too. Of course, now i see the 5811s and those look even better. Should I spend the money to switch??

I got the V12ip because it had the built in internet communicator but I shoulda got the backup cellular communicator right away like Alarm Grid sales guy recommended. Instead I dealt with annoying Comm Fails for 2 weeks before I came back to get this. Now I still get Comm Fails when my internet goes down but I know my alarm is still online and my Total Connect account always connects.
