Question about GE Security Simon 3 Wireless Home Security System

1 Answer

New Home, existing system, no information on what current access code is

My wife and I just bought a home that was foreclosed on. When escro closed we received one key and one garage door opener and nothing else. This was fine and dandy until the alarm system was accidentally activated. The Alarm system is a GE Simon 3 Security system.

Is there any way to do a hard reset on the system so that we can enter a new access code or reset it to a factory default code or something? I'm about ready to take a hammer to the thing just so we can open windows and doors again without fear of setting off our own security system

    Thanks Jane Deaux. I think I responded to your solution on another post as well. I have managed to figure out how to shut down the system. But I still can't get it to a point where I can enter a new access code. My system's main power does appear to be in some inconspicuous place. At any rate, I removed the main power by detaching the incoming power lines from the main board itself. They were attached using screws, so removing them was not an issue. I also detached the system battery as well. I will leave it detached for a few days to make absolutely sure that I just didn't leave it detached long enough, but leaving it detached from all power for 10 hours didn't seem to do it.

    There are two unused plugs on main board, one is a 4 pin plug and the other is a 5 pin plug. Are either of these used for gaining access to system settings or for resetting the system (ie such as jumpering certain pins?)

    Incidentally, for anyone else who is just trying to get a quick fix to the alarm going off without destroying it, you can unplug the alarm speaker from the main board. This does not disarm the system, but rather, just mutes it for you.

Powering down for several hours should reset the code to 1234.

To power down, find where it plugs into the wall. It'll be a big plug, about the size of your fist ( a three-inch, block style plug), black, white or beige in color, probably a little screw holding it in. It may be directly below the panel or could be in the room on the other side of the wall of the panel. Otherwise, it may be in a garage, basement or attic. It may be in a weird place, like behind a couch in the living room or on the ceiling in the garage. Good luck finding it!

Next, disconnect the back up battery. This can be tricky because it's really easy to break the little tab that holds the compartment shut. With the cover open, look at the top of the panel or the sides/corners. CAREFULLY push the tab, open the cover and disconnect the battery.

Leave it powered down for 24 hours and then plug in the battery first, then plug it into the wall. The code should (hopefully) be 1234 now.

First you need to have the installer code. Open the fromt panel of thealarm and enter in "4-3-2-1" (Default installer code) If it accepts this number then you can begin to program the doors and windows. If you don't knowtheinstaller code you mayneed to default the system and reprogram everything. If you contact meIcan walk you through the processor.

Your system is manufactured by Napco Security Systems of Amityville, New York. Call them at 1-800-645-9445 and request that they provide you with a security dealer in your area. The dealer should be able to access the system's internal data and retrieve the user code for turning on and off your system.

Need to change access code, but need ID. Is it on the main unit

Normally the default codes are either 4321,or 1234.

If those don't work you should try a reset by. first unplugging the red wire behind the system and unplugging the ac adapter. Then you press at the same time the "cancel button" "clock set button" and the "minute plus button" while plugging it in. After that the code should be either 4321, or 1234.
