alarm batteries

How will that work when it becomes snap the fibre?

[Martin Brown]

I though high density PU foam was de-rigueur for that these days.

Same way if monitoring sends a ping and doesn't get a response. They try to ring the alarm contact number(s) and if no response (or the duress code is given) a priority police visit.

But on nearly every car crash you see on TV, the whole thing explodes into bits? ;-)

Have you figures to support this 'quite likely'? And why would they be more likely to burst into flames than other battery devices? Everything has a risk. Like a diesel spill killing a motor cyclist.

I think you will find there is no requirement to register a DIY alarm. There isn't any need to register any alarm that doesn't communicate with the outside world by e.g. phone.

There is a requirement to register one that is monitored or auto dials the police. There are also servicing requirements for such a system.

The same way as the bell boxes work, you need an active signal to hold the alarm off. Its why the damn things go off in a power cut, no power in the panels battery to hold the no alarm condition.

Usably a very small rechargeable pack. About 6V in mine but less than AA in size.

Diesel spills don't kill motorcyclist, motorcyclists kill themselves in many cases. They appear to think they can take bends at the same speed as a car when in reality they don't have a chance on public roads. Cars stick to the roads far better than motorcycles and its not as dangerous if they over do it. Roads are pretty unpredictable as far as friction is concerned and a small bump will throw a motorcycle off but have virtually zero effect on a car, especially one with working stability control.

Mine has an STD which dials my mobile phone. Nothing in the instructions saying it has to be registered.

[Dave Plowman (News)]

Have you got data for this hypothesis?

[Steve Walker]

Yes there is. It is about noise nuisance - as stated in the act that I have noted above.

Do you know anyone that has registered a DIY alarm?

[Steve Walker]

As I said, it is unlikely that people do.

Doubt they often cause any noise nuusance. Seems to be the ones installed by cowboy 'pros' that give so many false alarms.

[invalid]

just don't set it to dial 999.

There is no such requirement in England or Scotland or Wales, there may be in some parts of Northern Ireland.

[Steve Walker]

It was in place when I fitted the alarm in 1993, I still have a copy of the form somewhere, but likely in the loft.

Since then the legislation has changed and I have twice quoted the title of the legislation "THE CLEAN NEIGHBOURHOODS AND ENVIRONMENT ACT 2005," which actually reduced the requirement (from two keyholders to one and only in areas designated by councils), but has been in force in both England (since 2006) and Wales (since 2006/2007).

Why not read it?

That allows councils to designate areas, it does not mean they exist.

[Steve Walker]

The rules were in place here before that act. People are more annoyed than ever by noise now, so it seems unlikely that no council anywhere has implemented such an area. It is up the the householder to check whether they are in such an area when they install an alarm.

I was under the impression that the Police required any alarm that required response from them had to be via a third party monitoring company.

These days most people will just ignore other peoples alarms going off and always assume a false alarm. It may be better just to disable the external sounder/bell and just leave the strobe lights. If someone has broken into your hour unaware that there is an alarm then the internal sounder fitted to the alarm panel/controller is likely to scare them off.

Whats more annoying are car alarms. At the junction of the road where I live there is a mini Sainsburys corner shop with. At least once a day someone will park up for that 5 minute visit and the car alarm will go off. I sometimes suspect that its always the same car every day.
