Hi, Im a newbie to this site. I have an old Scantronic 9200 - well 9210 alarm and remote keypad (please dont laugh i loved the 80's), after a lot of reseting i have managed to get it all working with the internal speaker. I want to create a mini bell box module circuit which will flick a relay when the alarm is triggered , but to do this i need to understand the interface from the control panel and i'm clutching at straws atm - any help is appreciated ;-0 I have the following from the alarm control box : Pin 1 - TRIG + / Hold + (constant + power supply ??????) Pin 2 - TRIG - / -VE RINGING Pin 3 - 0v / Hold - (constant - power supply ????) Pin 4 - TR / -VE Tamper return. Im assuming that i can user P1 and P3 as a power supply (regardless of the alarm being triggered or not). what isnt clear is how: I put together the tamper circuit (I'm guessing P4 is involved) Detect if the alarm has been triggered which I'm guessing will need to involve P2 ? Im probably over complicating things but any help is appreciated . Paul.
