Ex-burglar alarm, Southwark • Good news: this rusty old bell box remnant is the last “skeleton alarm” for now. The age and long, narrow shape suggest to me it may have been a Brocks, of which there are others in the area. Or perhaps it was a fire alarm? I await expert advice. • Spotted: Price’s Street, Southwark, London, SE1, England, 2010 • Politics: In the Liberal Democrat constituency of Bermondsey and Old Southwark

Does anyone know how the sab would work because I’m not seeing any relays or anything like that.
They continued to used those bells up until the 80s with the Chubb Delta 3 using those bells and is that a sab with a nicad but odd for the 60s
They 100% used those in the 70s still. Yes, the bells with the side clanger were easy to stuff, cardboard or rags did them in. Very basic equipment. I first saw a bit of modern kit when I moved to Chubb mid 70s.
Yes it was Brocks, but in those heady days we use to call the SAB a DEAC. I seem to remember the control panel was a PC52A. Tamper loops through the bell box was common practice in the 60’s. Then plunger micros on box cover assembly and then the plunger would be engaged by a screw in the wall. High Tec in those days. Then it went silly anybody remember the old AFA dustbin?
Thanks for your comment – you’ll be able to post without waiting for moderation from now on.
Yes I agree it a brocks outside bell unit with the nicad cell backup
also the old tangent hammer bell,you find these bells also in the old Autocall alarm system,came across them when with AFA 1968//
I agree with Paul. it’s an old Broks Alarm. Amongst other things, the tale tale give away is the round mental part on the circuit board above the bell, this was the nicad rechargeable battery. Note that there are no tamper switches. They u sed to feed tamper wires through holes in the cover.
Thanks for your comments – glad to have another knowledgeable contributor on board!
I worked for Brocks, and ye remember the way single wire was looped through holes in the sides of the bell case…very ‘Heath Robinson!”
Blimey that is old! :-o Yes I would say Brocks from 70’s (or even 60’s!)
Definitively 60s, unless it was a PJ and he used an odd bell he had kicking around.
Lucky that structural bracing is only it’s secondary job then!
I see the other box is holding the wall together!
The wall got knocked down shortly after so it didn’t do a very good job!
This is really old, before my time 1969, if this type of bell was to be used inside it would be easy to insert cardboard or something else to stop the hammer hitting the gong. This type of bell was used for many years in fire alarms.
