My brother is 6 years older, in our respective teens safe sex was having a padded head board - no bed, just the headboard! If you caught something back then it was curable at least, if embarrassing. You were more scarred of your Dad catching you smoking - his fags! Having a severe OCD about hygiene, If my brothers casual wild oats were being sewn now, he'd likely wear a condom for a hand job . Just thinking, i wonder in the bottle if Detol if it had a health warning on it 'might contain nuts'? If that was all it contained back then lol!

i'd be interested why you dislike it, i've had very few problems, worst tbh is GSM signal being reporting as low signal strength. I've trusted it that much i installed two systems to look after a high value warehouse complex until client had tbe budget to go for renewed wired. Guards love it, they can see immediately where when a detector has tripped direct to the patrols mobil if out on patrol, no need to go to the only available keypad to find out. top kit imho,

Many footballers like to smother themselves in white horse liniment - making it a bad mistake about not washing hands to copy if they then make a 'comfort visit' just before the match . My older brother had a chance casual relationship, a short while after decided he had risked catching an SMD, to shy to seek proper advice, he performed some self medication, pouring neat Detol over his cannon and balls! so if you think you know pain, he was off work for over a week in hospital with shock! , sympathy only please, no sniggering at the back

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 .

If you come across any old kit and you need help with, feel free to pm me, i might know about it and i'd be happy to share any information i have. looking back, i wish i'd kept some of the old panels i ripped out in upgrades, the skills those guys had. control panels were made on site, from raw materials, they even hand made the relays and wound the coils, the workmanship was just stunning.

Early AFA panel using flags as both control panel power and so called 'end if line' circuit batteries design, had two relays with a mechanical gate latch, this kit was called 'lock block and coffin'. The lock-block in its simplest form had a push button and key the equivilant of todays keypads, the coffin was the end station In the Day position the bell relay was held by the gates interlocking arm, when you set the gate arm was moved away allowing fre movement of the circuit relay, bells or an agro buzzer were rung on exit having git outside user pressed a button to set and silence the bells. if the circuit was broken the circuit relay dropped and as both relays were now de-energised a set if springs on each relay in series, rang the bells. silence was restored with a bush button on the lock block having turned a key to activate it, the adjustment was pretty critical as was those springs being clean it was used by many companies like Rely-A Bell, Brocks, Banhams Etc, but i don't know which had the original design or copywrite.

I know these as Aritec's Advisor 3, had single units or multiplexed versions, also transmitter only units as range expanders. Pretty good by comparison to other kit like AES (which had rubber bands supporting the transducers OMG) in their day tbh, had a little led test module called a 'BDI' - Background Disturbance Indicator, used to 'see' any low level noise. You could change out the transducers, but usually you just had to squeeze up the plugs that connected them to the pcb. (same issue in all the Advisor Range). i proved i could actually hear them, by accurately saying when or off when operated by another engineer testing me, i had the advantage to be able to detect a warbling transmitter, but the disadvantage of extreme discomfort if i was close by, as it was very loud to me. Because any high frequency noise could cause false alarms, you got used to listening/looking for things like escaping air from compressors, time clock, phone bells, door bells etc. even squeaking fans. and thats in too of all the other false alarm causes. happy days lol!

cheeky git , no, looks like a 'home brew' to me.
