true, that's looking at it positively
however I can see then being sent out on job & being left or broken somewhere, there also about £70 dearer than a set of triples....
If you had picture taken in the same postcode or with something the grainy tat from mobile of the same vintage as the sounder (1990's)
I'd guess at in being the remain of the fly lead for tamper switch ?
Its all redundant, just buy a new external sounder the one you have is tat once sold in wickes...
If I was a betting man-
I'd wager you've more chance of getting a hand job off her majesty the queen than your powered down alarm making the "chirp"
You've probably got a brand new in box, carbon monoxide or smoke alarm in the cupboard....
no,
the alarm pair should be red & yellow -positive colours for the positive loop
The tamper loop should be blue & black - negative colours for the negative loop
the new fangled powered devices should be powered by white + & green -
however we don't do any of the above !
shock sensors have a 1st to latch,
in these primitive pre mobile phone days... alarm men used to drill a little hole in the cabinet & fit a push to break switch which removed power to the vipers making them reset....
I recommend getting a proper alarm co. to fit a proper alarm ?
remove mains power before opening lid,
remove battery within metal endstation,
any self contained bell (internal or external) will ring for 20mins if it has a cut out timer or until the battery is flat if it does not....
now sod off...... ?
cool, all you need to do is get in touch https://www.bsigroup.com/ & ask they rewrite the standards for you
is he's coming for free...... or are you using Robin Bastard Electrical ?
A scam would be asking £198.00+vat, doing the work then charging £398.00+vat
I often say to people when they moan about costs.....if you don't want it, can't afford, or just don't like the price. Don't have it.
who'd have thought a jobbing electrician charge less than multi national company with 24hr call centre ?
ADT, grand + over 3 yrs ?
Fiat 500 from 20k, Fiat or the Fiat dealer is unlikely to help a private person do anything with their own car ??
