A prop made for a BBC production which required an alarm panel that could be mounted anywhere in an existing building during filming. The prop department supplied their choice of existing alarm keypad and I modified it to run from internal batteries and give the choice of a green "unset" indicator or also some channel LEDs flashing as if an alarm has occurred. Like most props I do, this one contains a microcontroller, so each LED can be programmed to perform exactly as required.
Be interested to see the drawing for this, I have an old Veritas keypad
Aaah, Good old Texecom! – I work for them now 🙂
what show was it?
