Hi all Service engineer with scottish company.Has anybody any info on racal guardall Map 6

 

It divides one panel zone into 6 separate latching circuits. I suppose not something you see about much any more.

The map six is wired in series with what look like diodes across each circuit. The diodes are all numbered and when the circuit is open it changes the current flow on that circuit so the panel knows which circuit is open.

A very clever design, bit like how ID systems work nowadays.

iD ... nowadays?

I have a site with one, he has a proper alarm as well, but uses the map 6 to check if doors are open before setting, the leds are active wether its armed or not. I would say its 40 years old rather than 30, late 70's early 80s.
