i recently had to switch off mains power to my house. at the point of
switching off, my alarm sounded for a minute, then went off.

after returning power to the house (around 30 minutes later) i noticed
that the TS690 alarm panel in my hall was now blank (no text) however
the green light was on indicating it was recieving power and the
backlight to the LCD display was lit.

has anyone an idea what might be the problem? im stuck now with the
external alarm box light flashing as i cannot use the panel to reset
the alarm.

any things to try would be most welcome

thanks in advance.
