The three keypads in our home started to warn against a low battery recently (AC LED blinking red and audible warning) and knowing next to nothing about this installation I luckily came across this forum.So basically I removed the 12V 7AH battery (been in there for around 4-5 years) and replaced with a new one today.  The system seems a little happier but the Home LED is blinking green and I am not sure if I have to do something to return it to the normal green steady status.Any help on this would be much appreciated.If you need more info on the system I will try and upload some images if needed.
Thanks in advance

Try pressing the following on the keypad: F then 3 and finally 1. This initiates a battery check.

New batteryies may not be fully charged.
The 1st time you do the battery test it may give Battery warning but when it is charged then there should be no battery warning
By the way the battery test is done automatically every 24 hours from the kast time you do a batery test

Hi
I pressed the F then 3 and then 1 to do a battery test - nothing really happened.When I press 1 the voice just says 'Battery test' again straight away and then lists the other options.
Thanks

If the battery is low, F31 willl report Battery Warning, followed by Battery Restore (as the test ends)

if the battery is good, there is no announcementy

Hi,
I did replace the battery so at least we can rule out there being an issue with the new battery.My manual states the following as other possible causes for blinking Home
LED:
1. Phone cut (not sure how this is setup but nothing has changed)2. AC Fail (I assume the system is running on AC currently?)3. Zone trouble (not sure how to troubleshoot this - assumed all settings would be stored in NVRAM somewhere)
Thanks

The LCD should report thr trouble which caused the green led to blink
If you have not signed in to your keypad since the batery warning then the greem will  still blink because you have not acknowledged
Sign in with your code on the keypad to acknowledge and check if the green is still blinking

I went through the process of changing the sign-in code which was successful.After that I now get the AC light with a steady red LED and the Home LED is still blinking green.
Does this mean there is an AC fail?
Thanks for all help slychiu

Not knowing much about the components of this system would you have any suggestions where to start troubleshooting as everything else in the property is operating without issue?
Thanks

If you disconnect the battery, does the system power off?

If so I would check the power socket that the Comfort ias connected to has mains voltage, and the connections from the transformer to the Comfort 14VAC terminal blcok

I disconnected the battery and the system goes off completely.The unit is connected to a mains socket using one of these https://www.cheapalarmparts.com.au/products/Transformer-Plug-Pack-18v-TF008%252dB.html

The power socket itself is OK as I connected a lamp to it and the wires from this power plug seem OK in the terminal block on the main board.Do you think maybe the power plug/transformer has died?Forgot to mention this earlier but this problem seems to have come about after our street had planned power outage for maintenance work.
Thanks

The most likely culplrit is that plug in transformer
If you have a multimeter measure the output wires connected to the Comfort AC In. It should be 18VAC
If not just buy another

If power was off for a long time and the system was runnng on battery, that may have drained to battery to very low and damaged it, since the battery  was already many years oldf
