Question: How many sensors are included in the box? I need total of 7 sensors.
Document: I purchased a custom Simon XT system for my mom & dad - so I had it shipped to me, programmed it and then gave it to them as a gift. I have a GE Concord 4 system with a combination of wired and wireless sensors, and this XT is nearly functionally identical, especially mow that they have added cellular and X-10 options. To address the two most common complaints - ease/difficulty of programming and "defeatability": the included instructions are not difficult, but they are incomplete for some installations; you need to search and download the installers "installation manual" in addition to the included installation "guide".
I would like to have done z-wave and home automation which I couldn't do.3) Expensive: While finding sensors for this system is relatively easy, the sensors are very expensive. As much as up to 50$ just for a door window sensor!! !4) Unreliable: This system can be very unreliable. Sometimes it fails to notify me when it goes off and other times it doesn't notify me that a sensor has been tripped. I have struggled greatly getting the box to connect to additional keypads.In all, I bought this a couple years ago before newer systems were available.
received product w/ main panel defective - not powering up on a/c, only on battery. Panel lacks ease of use. does not have a panic button to activate the siren. no stickers are included with any of the sensors. purchased mine from avsx tech, ana amazon seller. after 3 business days I hadn't heard a peep from them regarding a return.
From the ratings & reviews I researched on Amazon, the Fortress S02 series seems hopeful. For your own security and peace of mind, do not waste a dime on a GE Simon labeled product. I would much rather it worked than talked. If it can even talk, why cant it work?I stand amazed that in our days of fairly advanced electronics, it is apparently so difficult (judging by so many poor reviews of so many security products) to get good quality remote security sensors that perform well? The market demand seems strong enough, but the "foreign electronics" don't seem to be up to the security task, for some strange common reason, known as "poor quality".
I had no issues programming or installing this system myself, but I agree with other customers the instructions are woefully inadequate. If you want a clean installation (i.e., no dangling power cords or wall warts), unless you are a hard-core DIY and pretty handy with general electrical wiring, look for a professional to install. I'm handy, so I had no issue deciphering the spec sheets included with the equipment and performing the install. Regarding the general programming of wireless sensors, again same issue with included instructions, but you can find great videos on YouTube that provide step-by-step instruction, which is what I did.I also purchased the XT remote touch pad (Talking TouchScreen), two additional motion sensors, and an inexpensive external siren.
I picked this up with the extra 2-way lcd panel and I couln't be happier with the system. A lot of people have been complaining about the install. I mostly stayed away from the user manual and went online. Many youtube videos exist (try the ones by SafeMart which I found the best) that show you how to install this system from start to finish, including programming. Program the system right infront of your computer as you watch the videos and then install it afterwards. I had it wired up with 3 window/door sensors, motion sensor and control panel and had them all mounted and up and running in about an hour.I am using this for self monitoring so I have not yet got into the auto dial functionality yet, but that will come.
This is a reasonably priced alarm system and it works just fine. I haven't hooked it up to a service yet, but I was looking for something to set off sirens and scare off typical "smash and grab" amateur crooks that I was a victim of. Police usually get there after the fact anyway. The wireless sensors are a snap to install and program in, however you still need wiring for the power supply, telephone line, and remote sirens, if you are going to be using any. Remote key fob control makes it easy to enter and exit.
I bought the unit a couple of years ago and installed it myself. Here are some pros and cons I have found over the years I have owned it:PROs:1) Expandability - GE is an extensive company and sensors for this device are easy to come by. I have expanded it greatly since originally buying just the base unit.2) Functionality - while the functionality could due with some improvement (it would be nice to have z wave integration already integrated in this device, without the need for additional equipment and monthly costs) for an in expensive unit, the functionality is impressive.
Bought the GE simon XT kit for about $200 from Amazon and this kit is awesome! This is the same kit which professional home security companies offers you! Easy to install (wireless sensors), has alarm trigger calling feature, and offsite system status check!You dont need to use the monitoring service (ie. ADT), you can set it up where the system will call you if the alarm is triggered (I use the landline feature for this / i heard others say you can use non-landline feature for this but you most likely need to add-on something to make this work).
Definitely an easy install if you are good at DIY, otherwise there are plenty of resources on the internet/youtube to help you with the install. Also you can find many wireless peripherals that work with this kit (Simon XT) on amazon, ebay, etc. For $200 you get the starter kit (control unit with battery and wiring, 3 door/window sensors, motion sensor, and a remote key FOB) ~ the sensors may or may not be sufficient for your desired security coverage for your house BUT you can buy other sensors (i bought another set of 10 used sensors on ebay for under $100) that work with this system.
Answer: My kit came with 3 door / window sensors and 1 motion sensor.  For my house, I had to buy quite a few more (bought the GE nx 667 sensors) the GE nx 650 will cost you about $10-20 each. Shop around on eBay for other types of GE sensors ( most will work this control module). I think for my whole house application, it cost upwards $350 for everything (tons of sensors plus batteries, control module kit, and 2 remote fobs).
