Pretty sure they were known by what you mentioned there. I used to have an early model 45 panel which was quite basic bit still quite a lovely panel. I have one of those plastic things that goes on the key switch if you want it? To get that 41a working again -
Any recollection on the SCB module inside the maxim alarm box's? I was told ages ago that it was a small transistor module fitted underneath the alarm bell?

These detectors will be probably from the 1960s, the circuit board is made out of phenolic which was obsolete by the late 1960s with most circuit boards being made from a fiberglass material. not to mention the strowger 600 type relay being used. Also those bakelite terminals.

I have just noticed that the keyswitch is missing the plastic arm that pushes the Microswitch in, and that also allows the solenoid to lock the key switch

This is class to take a look at. Always loved the shorrock gear, finally obtained one of their bell box's recently too.

I was lucky enough to obtain a model 45 dating to the 1960s early 1970s. It was a shame it didn't work so I gutted it. Wish I didn't now as I probably could've gotten it to work again. -
Hi, bit of a long shot as these panels are very old and most are probably skipped; but does anyone still have a modern automatic alarms traffic light panel? And are willing to sell it? It's a hammered silver panel with a sidleen barrel key switch and its distinctive red, yellow and green lamps fitted to the top of the unit.

They are pretty modern looking, brocks seemed to always be ahead of the game. Look at two of the most well known companies in the industry, AFA and rely a bell; they were still hard wiring telephone relays whereas Brocks had circuit boards with transistorised circuits with built in bandit circuits and such. I've seen the diagram for the PC panels that came out around 1965/66, very very fancy technology wise for the time.

Here's one

Yes. The original brocks alarm bell cover from 1962 to around 71 were gold coloured.
-
Old that is. 1972 I think these came out after they stopped using the gold brocks.

That's a shorrock isn't it? Reminds me of the Model 45s- 5 comments

Having an alarm running on batteries is NOT a new idea

That looks like an old AFA panel. Usually they had those bell relays and the sigma low relay in a blue AFA drum fitted inside the premises. Are there any more photos of this system? -
Nah, do it for enjoyment

I refurb them yeah, bell boxs, bells and panels too. I think it matters if the PCB wasnt period.
