can anybody remember the franklin panel green one with a bakerlite opaque display with 2 bulbs beneath it? it used to buzz if a cct was open or if the ccts were clear set by shunt switch.
remember pulling one out following break in,smashed up like hell, choppped all wires, as i had sold a brand new scantronic 9100. only unfortunate thing the installer had run the 240 supply in 4 core alarm cable needless to say my cutters ended up the other side of the room. they had used red as live, black as neutral and twisted blue and yellow as earth my 1st bite from mains AFTER THAT EXPERIENCE I never touched a franklin or anything that company installed without a mains tester close to hand
