Safewatch Plus Entrepreneur, blinking lights

[wildpig1]

Hey to all first post in this forum,
I have a safewatch plus model a910kr and keypad. I had proplem with transformer and thought I had it solved,I had lost high voltage to transformer, Repaired high voltage and keypad kept beeping, checked battery had 12.9 volts at terminals disconnected from system when tested. I did a momentary wrong connection at battery lead reversal, corrected leads quickly aprox 1-2 seconds. Now there is a 3 Flash or blink on both trouble and alarm together. I tested system and it seems to be working Im convinced something is wrong with blinking lights and I dont want to damage further. I dont want to call ADT they will try and sell me new system,
Thanks to all that can help

I assume your system is NOT monitored or under contract. If either.....you need to call servicing company as any changes by you is probably a violation of the contract.

If you own the system and it is not monitored.....power down the system by unconnecting battery leads and unplugging the transformer. Wait about 1 minute and hook it all back up. You will probaly have to set the date and time.

See what results you get......the switched battery leads may (may?) have fried your circuit board.
