I may have got that wrong, I don't know. The lighting may well be a radial circuit. My only interest was to whether the practice of East / West rings / radials was unusual.

Has anybody heard of houses where the power and lighting rings are not uniformly Upper & Lower. I heard years ago where one room on each floor of a house would obtain lighting power from the other ring. So that there would always be a single light on that floor if the fuse blew. But while at my...

Would I be able to include (do they sell) a Dual Tech PIR on the Visionic system as I know that Yale do manufacture them? I ask as I have 2 rear facing (south) doors where the rooms in neighbours houses suffer from false alarms with normal PIR's. I know it's a topic of conversation in itself...

Trying to get to grips with a friends alarm system. I have already been given help with PIR's (thanks to all concerned) but now I am stuck on the fault log - or lack of it. After activating alarm either from PIR or door access, the panel doesn't show the zone which caused the alarm. I go...

Thank you for a very easy to understand explanation. Do you have any recommendations for an alarm system that I may fit to my place that would be wireless and have a Dual Tec PIR for the rear of my house. I considered the Yale for ease but they too don't have Dual Tec's. I'd be happy to spend...

A friend of mine had an alarm system fitted - an Infinite Prime with 5 PIR's and a door sensor. Since it was fitted he has had problems with false alarms from the south facing rear of his house. When recalled the engineer never suggested a Dual PIR but scratched his head and just played with...

The motor seem to drive on and off and operate the micro-switch. But when programmer turned off and the motor has driven back to the rest position, the valve remains open. It's as though the motor is not in fact driving the valve because it's permanently open. I obviously cannot see what the...

I have a CH system with 2 X 2 port Drayton Motorised Valves. The same problem has developed which came and went last year. The CH valve appears to allow water through when not required. When watching the valve it seems to operate correctly when programmer says on or off. But the valve remains...

Any recommendations on a DIY wireless alarm system that does use DT PIR's? Thanks for your advice.

Are Pet Friendly PIR Detectors the same as Dual Tech ones?

I intend/ed to install the HSA6400 from Screwfix but am flexible.

Can I get any wireless Dual Tech PIR's for a wireless Yale system. I want to install them in a south facing kitchen and utility room which have a lot of windows, sunshine, air vents and a boiler, It seem like the best option but I cannot see the anywhere. Any ideas, please. Cheers.

I need to install a new Integrated Cooker Hood in my ageing kitchen. It is to replace a broken AEG that has ben there since new. I have found a couple but the one sold on Screwfix has a negative comment that the width measurements of 605 because of proud carcase screws which would hamper...

That was certainly the case. She beckoned me this morning to confirm that she did indeed have the problem. Armed with this knowledge, I contacted the DNO (thank you Bernard for the URL) and they were on the case within 2 hours. The guy found the fuse arcing at the sub-station, and when...

I measured it at 247/248 when it is OK. But when it's flickering the voltage fluctuates between 238 - 249v. As I type it is OK but I am hoping to monitor it during the day and write down bad times. Last night at 23:00 it was particularly bad and I have had a spark check the CU again and all is...

Haven't noticed that, but will monitor it.

I have to confess that I only asked him to check the screws on the feeds as I was worried that the problem may be loose screws. Today I removed all the fuses barring the aux. one which also powers an incandescent bulb under the stairs where the consumer unit is. That light still flickered and I...

I have an issue with my electrics which only appears to show itself as occasional dimming lights. I have proved that the problem is not on the lighting circuits as you notice it also on a table lamp connected to the ring main. The problem is not constant nor can it be identified to any...

Although on the wrong forum, I wondered if any of you gas guys can help. Yesterday my wife cleaned the oven without covering the burner assembly. When finished the ignitor was constantly firing and it also brought my attention to some yellow flames. I removed the burner guard and it appeared...

Ok so I have managed to remove cowl and made accessing the burner assembly. I have given that a clean up (care taken) and where some Jif existed I have used a pin. The result is a nice even blue flame along the burner, But where the flame surrounds the ignitor it turns to a yellow flame which...
