6160 honeywell key pad is counting up with the word fault in front. Whats causing it and how can i fix it

Nothing but replace it. Something to check is open it up with the tabs be very carefull not to break them some have a small screw on the bottom. Once you have it open then try it and see if it is louder. I have found tape and plastic on some of them over the years. Try this and see if it works.

Power down the panel, remove the battery. Hold down the * and # while re-powering the panel. It will jump right into programming. Release the *and # button and proceed with programming.

There is no battery in the Honeywell 6160 keypad. It is powered by the transformer in the control panel. If it is showing BAT on the keypad, check the main system battery in the control panel.

replace main system battery. this will either be a 12volt/4ah battery or a 12volt/7ah battery.

Not Ready means one or more of your zones is faulted. Pressing the * key on the keypad will display the zone or zones that are faulted. A faulted zone can be a door or window open, a motion detector "seeing" movement, and so on. It will also display a description of the zone. Chime means the chime feature on the keypad has been enabled. Any perimeter or entry/exit zone that faults will cause the keypad to ding three times. This can be turned off by entering your 4 digit code and pressing the 9 key. Doing so again will turn it back on. The link below is for the user manual for an Ademco Vista 20P panel.

Hope this helps.

open ckt on the keypad refers to the data lines going to the keypad. check to make sure the yellow and green wires from keypad are properly connected.

It is located inside a tan colored metal box 12"wide by 15" tall and 4" deep; unless it is flush mounted, then only .5" deep. inside you will most likely find a 12 volt 4 or 5 or 7 amp hour battery. Note; the door may have a lock on it. I have found the key on top of the box, in the lock, and unlocked. The box could be located anywhere but, many times in closets, utility rooms, garages, crawl spaces, etc.

6160 is model of keypad the person answering this question will need system type located in control box.

I would check the connections first
