The "Chime Bat" message on your Ademco Vista keypad indicates that the battery in the chime module is low and needs to be replaced. The chime module is a small device that produces a sound when the system is disarmed or when a door or window is opened.
To change the battery in the chime module, follow these steps:
Locate the chime module. It is usually mounted on a wall near the main control panel or in a closet.
Remove the cover of the chime module. The cover is typically held in place by a small clip or screw.
Locate the battery compartment. It is usually located on the back or bottom of the chime module.
Remove the old battery and replace it with a new one. The type of battery required will depend on the model of your chime module. Refer to the owner's manual or contact Ademco for information on the correct battery type.
Replace the cover of the chime module and secure it in place.
After replacing the battery, the "Chime Bat" message should disappear from the keypad display
There are 2 Possible batteries one is a wall keypad unit the other is a panel unit. You may have a keypad without a battery so depending on your model start with the panel and work back to keypad as panel batteries generally last 3-5 years depending on how much your power went out.if you have a small panel 4x6 then it most likely won't have a battery and is powered from the panel battery.https://youtu.be/vbp4GIOhMcMif it is a larger panel 8x12 then it will have internal battery.On the keypad on top with flat screwdriver one tab on either side will open it. https://youtu.be/kGsCob_OCVQThe panel unit is about 12x24 but can be any size and was generally beige or light brown generally in a closet or downstairs. the panel unit has a larger battery about the size of a toddlers shoe box and these you want at least 7 amp hour https://youtu.be/ECI84eCynnsThere are 2 Possible batteries one is a wall keypad unit the other is a panel unit.

Best bet would be to try and contact the prior owner and ask for it! Should have left such instructions for you as part of the sale/exchange. Just try asking if it's possible to do so.
learn the two into the Code Encryptor receiver by pressing and releasing the black button on the receiver. The red light on the receiver should come on. press and release the closed padlock button 3 times, the red light on the receiver should go off
Within 30 seconds of power up press *and # simultaneously. Display should say 20, if you press *20 1234 then *99 to exit programming. Your system should be disarmed and your install code should now be 1234. You can then use this code to change the master code.
multiple low battery ones in sequence , mean a remote low battery. There is usually only one reporting zone on the remote (panic). That would be why only one zone shows alarm.
It should (If installed correctly) be hard wired to a fused unswitched outlet fairly local to the control panel, if that is the case remove the fuse and then the wire to the control panel.
If not you may find it is wired directly to your fuse box, a wall socket or even a ceiling rose. an electrician will easily be able to trace it's source.
An indication as to where it is wired can be obtained by switching/pulling each fuse/mcb in turn untill the control panel powers down.
