Zonaplex Posted September 22, 2013 Author Share Posted September 22, 2013 Thanks Arfur I have a few other old ones from the 70's I'll post up in a day or so They all work good with very little false alarms Quote Link to comment Share on other sites More sharing options...
bagpuss_24 Posted April 27, 2015 Share Posted April 27, 2015 OK old thread. The afa panel shown is an upgrade on the lock,block coffin installs. This panel is a multi circuit 'g type', giving the user zone indications via the panel Meyer. There was also a smaller single zone unit too. These panels were brought in with the drum bell boxes. The box on the right is an upgrade on the internal drum sounder, as it has the same bits and wiring in. The gtype was still manufactured as late as around 1977, where a 10 zone beast was available and about the same size as a suitcase! I worked for thorn between 1994 and 1999 and we had large numbers of these installations stil on our service books and working fine. I will have to Delve into the archive, but I still have all the circuits for them somewhere. Fascinating bits of kit, I have a single zone unit protecting my workshop!
