Mercury tilt switch, on a mechanism for the tamper!! NEVER seen that before! Way too elaborate for a tamper switch!! Fascinating stuff, control panel looks like it's been handmade (like a one-off).
Thats brilliant example of a 1970s panel you have there. So those two remote key switches are also known as pass switches. They allow the user to enter or exit a building without tripping the alarm and would usually be installed outside on a door frame of the E/E door. Also, that battery connector is for a an eveready HP1 battery. Or you can connect a lead acid battery. The bicc cable would be used as kick lace on doors or in knock out bars. And that tamper switch is a very clever, using Mercury to turn the switch into a tilt switch if the bell box comes off the wall.
@JamieVegas kick lace is what they used to call thin solid core wire stapled to door panels. Idea is if a burglar broke through the door panels to get into a premises, he'd break the wire during the process and set the alarm off. Knock out bars are the same principle. You fit a wooden battern on the top and bottom of a window frame and between is these aluminium tubes. With that same wire running through them. So if you smash through a window and break through the bars, more then likely you'll snap that wire setting the alarm off.
Wow! That tamper switch is very interesting, never seen one like it, that panel is also very strange (mainly the paint) i believe its by a company called acorn, they made panels that were used by standfast burglar alarms back in the 70s

Imagine if there's a burglar alarm system equipped with tilt bobs and slam switches from pinball desks

Thanks for the info!
What is kick lace and a knock out bar?

Some of the old Shorrock bell boxes used a Mercury switch as the tamper switch, many moons ago.
Nice video, I love the tamper system that the Type S has
wow you have struck gold there.
thats a great find.

Yeah I figured that yesterday when I saw the acorn in the middle of the ‘A’ on the front of the panel
Nice
