Installed alarm system into my m8s house (wow) using new pir,s and bell box but with a slightly dated A1 AJ600N control panel.

Problem is the bell box has everything built in sounder, strobe, tamper all covered

with a clear plastic and access to 5 wiring points, bell + - strobe + ov - and 1 tamper so ? is how do you make tamper circut with only 1 wire and how do i get the srobe to work as up to now all that works is the sounder. Or should I have used

seperate sounder and bolt on strobe with a micro switch tamper. thanx .ken

The Tamper circut will use the "0v" as the tamper feed and the tamper terminal as the tamper return.

Same sort of thing applies to the strobe, the negative willl come from the "0v"
