So in effect if you are moving around in a room where the sensor has gone into sleep mode it will not come out of it as it will not have had a 1 minute movement free period.

Just to clarify the sleep mode.
When the alarm is set and the sensors are active they will only go into sleep mode after they have detected movement. Therefore the sleep mode has no impact on the alarms ability to detect intruders as the alarm would have activated before sleep mode was entered.

Further clarification please. Does the sensor still transmit while in sleep mode ? YaleGuy seems to be implying that in sleep mode the sensor does not transmit a "motion detected signal" but does it still transmit "I am here" signals to prevent the panel timing out.

Suppose at the time the activation message from sensor to panel was being sent a burst of interference blocked the signal. The sensor cannot be told the message was lost so to ensure the activation has got through the sensor should be repeating the "motion detected signal" until it knows for certain the alarm has been activated. Bear in mind a valid signal from another sensor on the same system could be the signal that blocks that (apparently) one shot "motion detected signal".

Modern homes are being built without prewiring for a wired system.

Mrs Newhouse doesn't want holes in her brand new walls and they cant go under the concrete floor with a laminate on top.

So mrs newhome chooses wireless , which is fine because in a modern home with stooth walling the signals have absolutely no problems whatsoever and the systems work fine.

A wired system could fail to warn if the piezo fails
A wired system could fail to work if the reed sticks
etc etc

Whats everyone's point?
Do you actually know yourselves?

Do you fit wireless if requested mr Workshy?

Do you say 'Yes it's very reliable now' as you stuff the money in your pocket or do you tell them that there is (according to you scaremongers) every possibility it will not work?

So what is it?

Actually a lot if not most are prewired at building stage, where do you live in Timbuktu?
A good engineer can hide cables almost anywhere, your obviously not one of them.
Yes items can fail, as in a car a TV or any other electrical item. Are you saying your wireless does not have reeds nor peiozs? what is your point?
Why more insults/name calling can you not have a civil conversation? And yes I fit wireless, after a test at the RA/Estimate. And when I do I fit high quality two way reporting systems. With rolling frequency`s to try and avoid jamming. It is also mentioned on the specification given for the job, you do that I assume. Or do you just give the book you seem to like quoting from?

As your fond of quoting lots of spurious information, how do you combat foil backed plasterboard? I can, with certain equipment which is correctly placed. Can you?

I think your the scaremonger as your making out your items are foolproof, and you do not know how what you fit works.

Who cares - if you decide wireless is not the way to go then stick to wired and get left behind.

I make that decision based on technical facts and not the comments of a person whose prime motivation is sales and/or commission. I trust sales people who make very clear the negative features and short comings of the equipment they are selling.

Its only the same tech as car remote controls

They both use wireless but in very different ways

When was the last time you saw someone use a key?

Strange you ask that, I had to use the mechanical emergency key in my car's keycard the other day. It releases the passenger door lock for times when the central locking fails to recognise or cannot receive the key fob's transmission. A check later showed the battery was getting near the end of its useful life and the radiated power (ERP ) was probably very low as result.

Indeed and the only warning worthy of note so far - make sure you keep up to the battery changes or the system will not work...

Allthough unlike your keyfob the systems actually warn you when the batteries are getting low.

Sorry folks but none of this is really helping me as what is being debated here is more higher level.

I am surprised these forums are not administered as this is off topic.

I ask which specific Visonic system I should be looking at for my link and no one could really help.

Instead a more detailed debate was continued....

It still detects movement it just does not illuminate the led to save battery life.

Hi,

We want to get an alarm system fitted and someone has recommended a scantronic alarm system.

The specific system was the ION16 with multiple PIRs, door contacts and window shock sensors.

Are these good?

Also what other brands should I be going for when getting quotes?

What else should I be checking with installers?

And last but not least wireless vs. wired?

I look forward to your replies.

Thanks

Its the same thread activity that happens anytime anyone mentions either a wireless alarm or a Yale alarm , sorry

I can disable any wireless system with ease. Two houses near my house (nearest 200m other 600m) are knocked out by my radio equipment.... Regular false alarms etc RFI/ECM is a problem.

It's actually your responsibility, as a licensed 'ham' to sort out the problem that you are causing. If you don't and the problem is reported to the Radio Regulatory people, or what ever they are called these days, it is quite possible that your license can be withdrawn.

But I'm sure you know that., Don't you?

It doesn't work like that

If I'm transmitting from my home and I'm causing interference it's not up to me to knock on every door to find this out, it's upto the person I'm causing this to to inform me that I may be the cause. I'm then obliged to sort out the problem. Mobile transmitting is another story. You can expect interference when out mobile with all this low quality equipment out there but are not obliged to sort the problem out. An amateur would be expected not to transmit if he/she was aware they were causing a problem driving past a house alarm etc.

Problem the authorities face is the people who are quick to pick up a phone to make a complaint before knocking on the door. They are even more wound up when they find it costs to make a complaint

Just to add to the above. If my equipment is transmitting "clean" then I don't even have to fix the problem just try to. Much of the problems with interference from amateur radio ops is not their fault, it's usually down to the equipment that's having the problems, ie poor quality, agc and filters etc

SlowAlarms, I can do without your thanks.

I believe I gave you a link to the various systems they sell. scroll back. They are all there.

So in effect if you are moving around in a room where the sensor has gone into sleep mode it will not come out of it as it will not have had a 1 minute movement free period.

WRONG it is asleep and WILL not report.
Your not too good at this are you.
