    I have a home Ademco Vista 20P security system. It is 4 1/2 years olds and has worked fine until now. On the disaplay panel it has a zone number, 10, and "bat" flashing. The zone number refers to an entry door that is hard wired. I thought the system back up battery was probably going bad and replaced it. This did not solve the problem. What is strange is this entry door alarms when I have system in "away" or "chime" mode but not when it is in "stay" mode. As I said it is hard wired so I find it stargne "bat" is showing up in the display panel. Any idea what is causing this and what needs to be done to correct the problme?

    Hi My Name is Jeff Pauldo

    I own my own alarm company in south florida. On a vista 20p panel. that is infact a wirless zone. There is a wirless sensor somewhere in your house. The battery needs to be changed. It is out in the field or inside the main control panel.

    Thanks for the comments. On my the codes I was given for each of my zones, zone 10 is an entry door from the garage. I thought it, along with the other entry doors were hard wired. I know the sensor has wires comeing out of it. They run back into the door frame and not sure where a battery would be located. Is there any way to check out to to see if it is wired or wireless? Also where would I look for the loaction of the battery?I rechecked the central control panel. The only battery in there is the 12 volt back up battery which I replaced.

    Hi

    This is when it gets a little technical. This is just a technical guess. look inside the door jam. There will be a recessed circle like contact in the door jam. It
    will be above your head on the door knob side. That recessed contact can be wierless. Pull the device out of the door jam and replace that 3v battery. Thanks

    I did find a wireless device. It is a Honeywell 5800MIRCA. It appears to be a sealed device that will need to be replace versus relacing a battery. I am guessing there is a battery inside the unit. I did check in on the interenet to see what it was and the description says the battery lasts 10 years. It made 4 1/2. Another interesting part of this is it not in the door jam on the side. It is on the bottom on the door threshold with the maganet holder inbeded into the bottom of the door. Again thanks so much for taking the time to help. I doubt I would have found it otherwise.

    Hi
    That is indeed is the device my friend. The manufacture does say the battery lasts for 10yrs ;however, the more acurate duration is 3-5 yrs. The battery is indeed bad. Not the device. Your place of residence bust be up north. In the south we generally mount these devices on top because we have no basements. I think that will solve your problem. Replace the battery, put the device back into its place and put your code in and off twice to rest the panel.

    Yes, I am up North in Cincinnati. Already tried of winter. I don't want to sound like a pest, but I do have one last question. The piece or component with the magnet is recessed into the bottom of the door. The other component is the sensor with a long wire coming out of it, which is in the threshold. It has a while top and orange bottom. I am taking it the battery is inside the white and orange sensor. Can this be opened and just replace the battery or do I need to replace the whole device?
    Again thanks for all your help.
