Hi Spark123 I have just read your comments about your experience with Alertelectrical when you purchased (or tried to) some lamps in January. Please accept my apologies if our service has not come up to scratch. I have no wish to make excuses, we have experienced some growing pains during a...

I appreciate the negative sentiment over Response /Yale etc., but we have sold hundreds of Infinite Wireless Alarms systems over the last 2 years with no problem at all. It is probably one of the most successful products on our website and yes we do respond to all complaints so if there were...

Also try Smiths Timeguard or GJD which are generally regarded as a quality product. Has anyone heard of 'back EMF' between two PIR's on the same circuit causing the other PIR problems?

The PIR monitors the existing infra-red conditions and reacts to a sudden change in them. So if it was a human being there would be a sudden increase in infra red registered as we are a infra-red source. If there are inra-red levels inside the shed, like a heater, or a car if it were a garage...

Buy the spider a proper spider bed so that he doesnt see the PIR as his best option. When you have alot of heat present like this weekend spaces like sheds can have a large amount of heat build up. Once that happens the PIR can be set off for a number of reasons, moving air currents some...

Ban: Can you expand on this a little bit please, or point me in the direction of the topic, are you saying that Building control have an imposed limit to what they can charge for inspection? What about when only electrical work is involved?

Yes the kits are far cheaper than buying the parts seperately; but the bits are available. I would have checked the minimum 70va load of the transformer as advised in a previous post.

Yes its like calling a vacuem cleaner a Hoover, Henley is a brand name.

I didnt say it was the requirement, just what you should be doing, as after all, there is just as much fire risk in a domestic dwelling as a commercial one. I suppose the plasterboard ceiling in a domestic dwelling does not have much fire integrity anyway, does anyone know if this is a...

So to answer your question, to avoid excessive heat build up you should ensure that the insulation is well away from the downlight, at least a 50mm air gap. And then to do a proper job and retain the fire integrity of your ceiling you should install a intumescent fire hood. I havn't got any...

Wired alarms are the system of choice for professional installers. If there is no problem running the cables then I would recommend a wired system because they are also cheaper than wireless systems. However, wireless systems gained a reputation for not working which still sticks even...

You can wire it using separate 240v pirs wired in to the same circuit switching lights of your choice. I have heard that this can cause 'back emf' between the PIR's which can make them not work properly but then again I've supplied plenty that have worked OK, I'm only quoting someone elses...

I was talking to the local NAPIT rep yesterday. It seems that the colleges are all over subscribed unitl September which is going to cause a problem. NAPIT seem less stringent in their joining criteria thean the NIC. Horses for courses I suppose, if you are doing mainly smaller work then...

Leave it, it can only help to have better earth bonding than is required.

You can buy Fitzgerald standard fluorescents at 110v. Just ask your electrical wholesaler for whatever fitting you would like with the 110v surcharge added, costs about an extra £5.00 from memory.
