Just how many cores for a wired burglar alarm?

That was obvious before you admitted it

It's okay, I'm not ashamed to be a DIYer. Although bullying them doesn't encourage others to join this forum

cutting it

This argument is beginning to circle vis a vis my other thread regarding no evidence of anyone ever tampering with a domestic burglar alarm.

an internal battery that will operate the siren

Hmm. I'm a little worried that an electronics designer has made this elementary faux pas:-

• The internal bell box circuitry can't supply the additional 1000mA+ of current for the strobe
• Even if it could, a strobe like myBX61 can't be electrically connected anywhere to the bell box circuitry

Some alternate thinking is required to solve this problem...

Pro equipment, sirens and strobes have to turn off at 15min

Thanks for the heads up. Some panels such as the Honeywell have the ability to set the alarm output duration via keypad.

Twenty Four, is there any way you might post the wiring for your alarm sounder /strobe arrangement without compromising your security? I think that there are readers here that would be enlightened. We're pretty much off topic now anyway. I understand if it's impossible.

Sometimes strongly worded advice can seem to be akin to bullying. Especially if the recipient would prefer to hear different advice.

There is plenty of evidence, but for various resaons it cannot be put into the public domain.

If the strobe was designed to be an integral part of the bell box then the designer would have made provision for the supply to the strobe.

A designer cannot add 1000mA of capacity on the off chance that someone will want to add additional items to the bell box. There are technical as well as cost reasons why that cannot happen.

It's not in his threat model of "14 year old smack head with an old screwdriver".

I suppose you'd like me to buy one of your spread spectrum (do you know what that means) wireless alarms for £5000, rather than a big padlock for my garden gate?

I don't sell alarms. £300 would get you a Pyronix Enforcer or Texecom Premier Elite, both of which use FHSS. Why would I not know what that means?

A big padlock for a garden gate wouldn't normally be a very wise purchase to improve security.

But then, I am speaking to someone who has removed tampers on an external siren.

Unfortunately not and I also can't comment on how it is wired as all I know is it's separate to the original bell box and strobe, is loud enough and bright enough to be heard and recognised from a fair ol' distance and dims the village when powered.

Thanks for the heads up, I'd never have guessed

Are you aware of the huge irony of this statement, made on the day the Chilcot report is published?

I'd suggest 95% of panels, if not more can do that, rules & regs have been around longer than you.

To put the evidence into public domain would make public ways to defeat alarm systems. It is clear from your postings about the "design" of your DIY alarm system that you have little if any knowledge about how to make a reliable and secure alarm system.

I'm trying to ascertain whether it's worth while putting lots of effort into wired tamper protection.

If someone doubts the need for tamper protection in a wired alarm system then it is clear that he or she has none of the knowledge essential for the design of a robust alarm system

I'm sorry that you can't see the irony, Bernard

My cat jumped onto the keyboard, and I posted a blank message that I can't now work out how to delete...

The cat jumped and you posted . So you can't blame the cat

I'm sorry that you can't see the irony, Bernard

And I am ( maybe not ) sorry you cannot see the need to tamper proof the bell / siren of an alarm system.
