Hardcore old ultrasonic?

 

Or something else?

I've no idea I googled the company they seem to Be still going but don't do intruder Alarm detectors anymore , maybe some of the old timers fitted some back in the day

Yes let's wait for the old monkies , there on stair lifts right now , as a side job of course 

An old sonic probably connected to a map 6

Early 80's?

 

Love that it's been made into an EOL circuit

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

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 

What was false alarm rate like ? Terrible due to the relay failures ?

infact assume relays failed closed anyway?
