petercts Posted August 8, 2018 Share Posted August 8, 2018 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 1 Quote Link to comment Share on other sites More sharing options...
Ashton Posted August 8, 2018 Author Share Posted August 8, 2018 whats the map 6? And it's peake on the back like you say metal enclosure looks in fair condition For its age I'll have to stick it on a battery get the Meter on it see if relays still working, ill mod it surely could get it up to grade 3 Quote Link to comment Share on other sites More sharing options...
Ashton Posted August 8, 2018 Author Share Posted August 8, 2018 (edited) What was false alarm rate like ? Terrible due to the relay failures ? infact assume relays failed closed anyway? Edited August 8, 2018 by Ashton Quote Link to comment Share on other sites More sharing options...
