that shocks me if true boom! boom! personally, sod that for a game of tin soldiers, if i fit one, has to have spur or plug, 3 amo fuse max i have always assumed the CU being mounted on a lump of timber is for insulation needs, or to get cables behind, but us that correct and still required? just tweaked my curiosity for some reason.

But then, how often do you see a door bell transformer alongside the CU wired to a 32amp rcd with twin bell wire?

the delay is so you have a chance to switch off and avoid calling key holders if you accidentally cause an activation during exit or entry. suggest check manual to allow dialler to cancel if alarm is switched off after activations, otherwise all you key holders will get a false call.

That is real old school, not seen 2 detectors in parallel deliberately installed for many years, but was used early days of motion sensors. no elephant catchers or quads back then, MWD and Ultrasonic 's were king.Principle was if one detector was tripped by a draft, the other stopped the activation, but a large target would trip both at same time. Could also be used for animals, as long as one did not cover stairs as example, better than stuffing large slug on the zone .

it's no different in principle to todays dual-tecs, back then even double knock, beam pairing or programmable panels had not been introduced. For false alarms if you could not find the cause or did not have the time, you installed a 1uf cap to "slug" the zone against intermittent's, idea being by the time that got bad enough that the cap could not overcome, it was easy enough to find on a swing needle meter.. trouble was some guys took it to the extremes, you'd find 1000uf installed, thief could open a door, have a bath, knick the gear well before the bells went off.

think i can claim ti be possibly the first to fit a Pir ind parrellel to an mwd. ///pause for astonishment/// before pir's were the first choice, on Chubbs the AFA MWD was favoured. Well sime chump specified one in the ceiling void. so whats the problem you ask? well this was Ratners Jewellers shop, under the railway line bridge in Southend High Street. Kept truggering surprise surprise, guy would not sign to disconnect it. so i installed what was then a very mew tech Racal 771 pir in parallel. Result was no more false alarms. Suprvisor picks up the report, asked who authorised it - explained - told to remove it, so i said yup! OK, but any calls you cover it. After 6 he asked me to go back and re-fit the pir lol! Anyone know John Chantry? if you do, then you can ask him .

and possibly fit 'pull up' resistors, should be in the dialler instructions.

breff stated 'coax staple gun', so a tool designed for the job, its boils down to experience, its not like using a club hammer instead of a pinning hammer for 6mm hiats . for a very short period i worked for a company that used staple guns to lace wire sheet panels under hardboard. no way did i want to risk attending to see large hole on door and rusted wire staples with no a tivation .

ditto +1 cable clips get brittle, offer a possible hazard to children chocking on dislodged bits of them, seen the pin not in the holder but forced through the arch. imho any tool in the wrong hands is simply two tools put together by accident - take a neon screwdriver as example lol! or perhaps not

Chris Tarrent ran a show a while back, invited listeners to share their finds after moving into a house, one said she opened the under stairs cupboard to find a URN complete with ashes. he remarks "she could have made an absolute fortune selling it as 'ready break' to the cannibals".

fapmsl git and again fapmsl

qfa,last thing i need is some fat old, wearing nothing but suspenders giving me the come on
