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.Well, I did this job today swapping out for an LCD based panel.
The two detectors in the initial picture...
Wait for it, wired in
PARALLEL?!!??!!
Or as the job sheet which I found (but sadly haven't got) stuffed on top of the cabinet said 'wire garage in parell'
Twisted wires to connect speaker in trunking - no insulation
Taped up twisted wire joints in loft
Somehow ran out of wires for SAB so joined Strobe to Siren!! (Lets not forget even old panel was PD 2010)
Front door contact was Grade 1 without tamper.
All from an NSI gold sold as Grade 2X. (Not a cash job or homer). Class and a half.
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

i dont doubt it for a minute....
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

You need to invert your trigger
and possibly fit 'pull up' resistors, should be in the dialler instructions.

Staple guns for 6 core etc = great
but for coax? a no-no imo. if you compress the coax you affect its transmission properties higher up the spectrum, making balancing of systems hard to impossible in some cases.ok, if its only 10 meters of cable, but above that, not worth the risk.
Im speaking from knowledge of large aerial systems, but the principal holds true in cctv cabling too.
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
. -
Nothing wrong with staple guns in the right hands, I've got a coax staple gun as well, very handy.
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".
-
not without pills he hasnt...
fapmsl
neither does the customer...
git and again fapmsl
-
qfa,ive never found anything except dust...you should always ask the customer if its ok to go upstairs,go in a bedroom etc before doing so,gives the customer a chance to move stuff,lol
last thing i need is some fat old, wearing nothing but suspenders giving me the come on
-
Just so you know if I leave the accounts lying around in your presense its for a reason,probably becuase I want you to have a good hard think about taking a drop in pay
lol!
-
the one thing you dont do is rifle thru a customers personal paperwork..wheres the truss...
lol!.
given i work mainly in domestic, found blue mags, questionable underwear, smelly cricket boxes, loads if 'secret' cash but never ever found sexual toys
.one very prim and proper lady, flawed me with a remark. due to me needing access she found some of her husbands porno. showing multi entry sex, one male 'model' had an erect fence post like appendage, on seeing it she calmly remarks 'guess its somewhere to hang his hat'.
just hilarious, un-expected reaction lol!

Imagine what he'd change arfs to
Arfur Thatcher?

as above these panels do like mains on before battery, this means you have little option than to have the panel lid open. please beware of the internal mains fuss block and your straying little pinky.
for best safety, disconnect battery remove then restore power from the mains spur fuse unit (or plug) feeding AC power to the controls (that should be near it and marked).

hour for hour recovery time after midnight, out for 3 hours (from leaving house to walking back in) start 3 hours later the following day.
i enforce that rule (as shop steward) on Chubb Eastern, after 2 guys within a month fell asleep at the wheel, during a very heavy lightning spell, which back then you knew you would be out all night.
i think only 3 systems nocked out by electrical storms since i started, nothing fried to dust, but knocked silly.
suspect if this reduction is down to mainly using polly boxes instead of metal - anyone think the same?
-
No worries. To be fair, Alpha Alarms up here used to use the green as pos and the white as neg for some odd reason. Still catches me out on occasion when swapping out a detector!
i use red/black for power, but i've seen green white done quit allot, think its a colour consistency preference. i.e. days if 4 core (obviously no G/W) for contacts, 6 core for detectors, so you could maintain the more common 4 core red/black for zone feed out, yellow blue for the zone return on DP systems.
today eol means you can feed 3 detectors from an 8 core, commonly brown/orange would be to the furthest device or pab, but maintain green white as power.
before anyone shouts and hollers, and gets all snotty, its what i have seen - not what i do.
-
you need to reduce those bare wires, cut them down so casing nearly meets the connector block.
be careful the resistors in the picture don't short out due to bare resistor leads and your exposed cable ends, which can happen as you close the lid.
nice touch is to use some sleeve casing stripped from larger size surplus cable, and put it over the resistor leads.
Just released what I wrote was a load of ********. Sod it off to bed.
just as well you 'released' it the

seems your sales ability is hindered by near complete ignorance of how to initiate and gain trust in a strangerno.3 a decoy bell which flashes & has a £90.00 pmv for wiping with damp rag & Arf believes would encourage people to buy proper alarms.....
i did not say or or suggest it will sell only alarms - i'd never be that limited. fact they want a decoy is enough to tell me they are worried about their security to some degree, but not sure they want the inconvenience of using one and the risks of false alarms, but perhaps not thought about cctv or video door entry as example.
Fortunately i've no need of this tactic today so i can choose, but for those starting or short of work fitting a flashing or otherwise decoy, is a simple way of getting invited in with no advertising costs.
your not leafleting, door knocking, cold calling or pressure selling - simply extending that cordial meeting. by using your sales 'patter' to put at ease, and gain their trust. Now you might offer to price no pressure, and if they go for a small sytem the decoy is included, all sorts of honest ways to close sales - 3 year warrantee's as glowing example
.but you can't do that without meeting them.

There's money in reverse engineering, trust me.
lol!

Nothing to do with ACPO, BS8243 was mainly written by installers & inspectorates, we have always had code and fob as an option as it is more secure. If you want to get involved join the BSIA and get your voice heard.
many thanks Adrian,
the refference to APCO requirements not allowing (i may well be wrong), but i thought that was a comment from i got from James? so perhaps i misunderstood.
this little tiny one man band voice is getting to long in the tooth to joins BSIA now, can you imagine the disruption i might cause them
. -
Don't disagree arf but as I keep getting told. Remember the golden rules, the one with the gold writes the rules and as compliance is mandatory to get a urn even if I think they are bollox I adhere to them to get what I need.
An pure example imho, i have said it before - about time the inspectorates stood up and told APCO it is 'us' the alarm trade who now how best to electonicaly protect vulnerable targets.
-
Only not allowed for one disarm method but because the rules say so.
Then surely, the rules, like the law "is an ass"?
-
Short question - if fobs are so easy to clone why is code and fob not allowed?

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.
