Ok so we had a power cut about half an hour ago. Since then my
alarm system has been unworkable.

The system is a Texecom Veritas Excel and has been reliable for years.

Initially when the power came back on, all the LEDs on the keypads
were lit, power, unset and tamper. But the keypad panel was
light green and it was not possible to enter commands thru the
keypad.
To try and cancel the various audio alarms, I removed mains and
battery power. Having powered all back up, I have nothing
showing on the keypad displays at all.
I have checked five fuses on the main panel board and all seem fine.
Anyone know how I can get the keypads and system to operate normally?

Did it fail loud immediately on power loss or after a while or on
restoring mains power?

I should add that to cancel the internal a!arm I have removed
mains power. The external sounder is now running almost
continuously. If I get access to the keypad I can send a hold
off command, but otherwise do not know how to safely silence the
external sounder.

I suspect the backup battery is flat and the alarm went into panic mode.
There should be a factory reset button or key sequence but that isn't a
lot of help if you don't have the engineering manual for the unit.
