Fitted these back before the days of map6   late 70s before the days of plastic  cases, used to be wired  first to alarm  latch ,had  to fit up to ten on a single zone panel at first now wired eol  nice to see an attempt to make it grade 2

 

Remember the case shape has it got Elkron  [Italian]or Peake [uk rip off] on the label it is  first detector I saw that had an led not a bulb 

 

They put  an old gunn diode micro- wave in that case, and ultrasonics with ceramic coils  and later even a single element  pir  he relay clicked so loud people complained  most failed and replaced with Aritech  Du series or later Racal 771 single element pir

R u retiring soon?

whats the map 6?

Map 6 was like a latching universal zone expander so you could expander one control panel zone into 6 devices.

Yes after 42 years [ a life sentence for murder is less ] and I do not  know how many installs or sales I  forget all the companies I worked for I am supposed to be semi retired but we moved house and I just had to rip the Risco wireless c--p out  I have found a proper use for the panel use it to hold shed door open it even cannot do that reliably 

One of the fist mass produced detectors to meet bs 4737  1971 that was not made  for one of the big companies or that  you did not have to buy direct in bulk and you could buy from this new thing called a wholesaler   they cost so much each one had to be signed for and the empty box returned

Most things in the late 70s had to be   made in house even  panels and out side bells, we even made door contacts   reed switch glued on to an aluminium plate  made in small batches   with final assembly by the stores man
