Zonaplex Posted September 20, 2013 Author Posted September 20, 2013 Brad, This is the Genesis, I remember the a-d split of the zone you had a different resistor for each detector, it was a pain on a service call as high resistance on a cable would really mess you up also the plug on connection for the MLI units need a special tool to crimp properly or your connection could go dodgy and cause all sorts of GIL status marginal high or low As far as I know Securicor Granley used to make them in the UK we could order separate circuit boards from them they looked like old PC cards, Securicor Dublin stopped using them around 2000, still a few around in schools and colleges in Dublin. Jnealon, That's the very panel a KES, I came across a Merlin 150 in the stores and the programming is the exact same The engineer manual lets you program fine Thanks for the help Quote
arfur mo Posted September 22, 2013 Posted September 22, 2013 Found this today,arf will know what it is.. .IMAG0405.jpg IMAG0402.jpg cheeky git , no, looks like a 'home brew' to me. Quote If you think education is difficult, try being stupid!!!!
arfur mo Posted September 22, 2013 Posted September 22, 2013 James, this is the old AFA stuff they had lots of old batteries called cells or flags I think, they were kept in wooden boxes around the site and seemed to be linked to the tube and batton stuff on the windows The Fidela motion detector still works perfectly on a newer panel and the lamp (not LED !!) lights up when it detects movement and the relay makes a really loud click sharedmedia=gallery:images:539] I know these as Aritec's Advisor 3, had single units or multiplexed versions, also transmitter only units as range expanders. Pretty good by comparison to other kit like AES (which had rubber bands supporting the transducers OMG) in their day tbh, had a little led test module called a 'BDI' - Background Disturbance Indicator, used to 'see' any low level noise. You could change out the transducers, but usually you just had to squeeze up the plugs that connected them to the pcb. (same issue in all the Advisor Range). i proved i could actually hear them, by accurately saying when or off when operated by another engineer testing me, i had the advantage to be able to detect a warbling transmitter, but the disadvantage of extreme discomfort if i was close by, as it was very loud to me. Because any high frequency noise could cause false alarms, you got used to listening/looking for things like escaping air from compressors, time clock, phone bells, door bells etc. even squeaking fans. and thats in too of all the other false alarm causes. happy days lol!

arfur mo Posted September 22, 2013 Posted September 22, 2013 (edited) Early AFA panel using flags as both control panel power and so called 'end if line' circuit batteries design, had two relays with a mechanical gate latch, this kit was called 'lock block and coffin'. The lock-block in its simplest form had a push button and key the equivilant of todays keypads, the coffin was the end station In the Day position the bell relay was held by the gates interlocking arm, when you set the gate arm was moved away allowing fre movement of the circuit relay, bells or an agro buzzer were rung on exit having git outside user pressed a button to set and silence the bells. if the circuit was broken the circuit relay dropped and as both relays were now de-energised a set if springs on each relay in series, rang the bells. silence was restored with a bush button on the lock block having turned a key to activate it, the adjustment was pretty critical as was those springs being clean it was used by many companies like Rely-A Bell, Brocks, Banhams Etc, but i don't know which had the original design or copywrite.

arfur mo Posted September 22, 2013 Posted September 22, 2013 It was just a hobby of mine messing about with old panels and detectors I have got many an old Aplex and Genesis going again in the shed, even an old AFA Fidela detector from 1975 !!! Thanks for the response anyway If you come across any old kit and you need help with, feel free to pm me, i might know about it and i'd be happy to share any information i have. looking back, i wish i'd kept some of the old panels i ripped out in upgrades, the skills those guys had. control panels were made on site, from raw materials, they even hand made the relays and wound the coils, the workmanship was just stunning.

Zonaplex Posted September 22, 2013 Author 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
bagpuss_24 Posted April 27, 2015 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! Quote
