Given that my first approach didn't work but my second did that left me scratching my head as to whether the keypad or the wiring was to blame. Using that approach, I was able to resolve and disarm the system. Using that approach I wasn't able to resolve the issue.Īt that point I thought that the control panel must have been at fault, but not wanting to give up too easily I decided that I should bite the bullet and disconnect the keypad at the control panel (terminals 6 and 7) and re-connect them one at a time. Since the wires were tightly/neatly packed in the control panel I didn't want to get into pulling that apart to separate the data lines into their individual pairs so I started by first disconnecting the wires directly at each of the keypads and then only connecting one keypad at a time. After a couple of hours of troubleshooting I have narrowed it down to a short-circuit in a wire running between a keypad and the V-15P control panel. Don't connect a live wire to power up a keypad: Connect first, then power up the thank you so much for your detailed response. NOTE: I STRONGLY recommend powering down the Panel (the V-15P) while disconnecting and reconnecting power (Terminals 4 & 5) from/to Keypads and other devices. That should get you a working keypad so you can Disarm the system.Īfter you have one working keypad, re-connect the other devices, one at a time, and test to see if the keypad(s) lock up after each device. You only need disconnect the wires at 6 &7, the data lines. There may be other devices.ĭisconnect all of them, then try reconnecing the keypads one at a time. Look at Termimals 6 and 7 to see how many devices you have connected. The keypads, unable to get feedback from the Panel, will lock up after a few key presses. If the system is Armed when that happens, the Panel (the V-15P) goes into alarm. If one device is sending garbled signals, it blocks signals from all the devices. They're all connected to the data lines at Terminals 4, 6, and 7 on the Vista-15P. It sounds like one of your peripheral devices (like your keypads and 4219) is garbling the data flow. Given that I can't use the backdoor method to get into programming mode I wonder if I should even attempt to use the factory reset command.Īnyone see anything like this before? I've seen one similar thread but that person seemed to be able to use the backdoor method to enter programming mode. I am not sure if the main panel is dead or if the extender module is dead or both. None of our other electronics in the house appeared to have been reset last night so I don't think there was a power outage. I think the "ALARM 107" code is reference to the extender module (4219) so I unplugged it from the main panel but that didn't change any behaviour. The keypads do respond to the 1+3 buttons to set the keypad address so it looks like the keypads are fine. I also tried having my wife hold down the * and # buttons while I restored the AC power but that didn't work either. I tried using the star(*) and hash(#) button method immediately (within 50 seconds) after powering up to enter programming mode but it does not enter programming mode. I disconnected the sounder from power to troubleshoot without having it blaring at me. After the initial minute or so passes the system goes back into an alarm state and sounds the alarm siren again. On each power up the keypad displays the "dl" code for a minute or so and then shows "ALARM 107" and then cycles thru "CHECK xx" where xx is each of my zone numbers one at a time. I tried different user codes and my master code - always the same result. The same behaviour happened - unable to disarm and keypads would freeze. Since then I powered up the system (AC only) and tried disarming it from different keypads. The siren continued to sound so I disconnected the AC power and the battery. I wasn't able to disarm the system because the keypads would freeze after 4 key presses (i.e., i would put in my 4-digit code and would hear a beep on each key press, but then no sound was made when I pressed the OFF button.and then no further key presses made any beeping sound). I was a bit panicked, and in a rush to figure out if the house had actually been broken into or if this was a false alarm so I didn't actually notice what zone was being reported on the keypad. Last night, we were woken in the middle of the night by the alarm sounding the siren. We have been using it in standalone mode (i.e., no monitoring) for 2 years without issue. I have a wired alarm system (Ademco Vista-15P) that we inherited from the previous homeowner.
