There is readily available access to where the connection would be made (behind the eaves wall which is accessible via a door from the loft room) so I'm hoping to just tie-in to the circuit with a regular JB. I may just pull the cable from A to B and get a sparky in to do the final connection...

Would it be possible to insert a regular 4 terminal junction box in to the feed between 2 alarms and spur off that way? Is that what you mean?

The light in the loft is on the same circuit as the first floor. The ground floor lights are on a separate circuit. Hope this clarifies things.

Thanks for taking time to respond. Getting a cable run from the last on the circuit is a bit of a bind and I haven't got a long enough length of cable! I am hoping that there is room to terminate in the closest unit-I imagine it will be very confined with the additional cable in there. If i'm...

Thanks for the response. I had considered those wireless alarms but pricing them up was quite "alarming". I would need to buy 2 wireless bases in addition to the extra alarm unit itself. The cable run from the existing unit to the proposed position is very easy to access and as I have a...

Hello. I've trawled through the forum looking for the answer to my query but to no avail, so here goes... I have an existing mains powered interlinked smoke alarm system in my house , comprising of 2 smoke alarms and a heat alarm. These are powered from the first floor lighting circuit and...

Hello. I am going to install a sun pipe in a bathroom that has no natural light and was going to include an optional electric light within the pipe. I understand that electrical installation in bathrooms falls under part p regs, but what about the connection of the lamp inside the sun...

Thanks for those replies. I've decided to put an additional layer of 9.5mm on either side of the stud wall instead. Hopefully this will aid with sound deadening as well. Thanks again.

Hello. Can I achieve 30 min fire resistance with a stud wall comprising off 75mm timber and a single layer of 9.5mm plasterboard on each side if the cavity is filled with a rockwool type insulation? Any ideas? Thanks in advance.

No, there was no sole plate. The wall was built directly off the floorboards. A timber strip (15mm wide x 10mm high) ran along the length of the base of wall and had a bed of lime mortar on it. This timber bead created a tongue in the mortar bed and wall panel located itself on to this, if that...

Thanks. After searching Siporex on the internet it appears that these are pretty much what I have. Aerated autoclaved concrete panels the general term for them seems to be. Still seem to be very popular overseas. The partition was dividing the upstairs bathroom, back bedroom and the landing.

Thanks for that. I suspected that they may be some kind of pc concrete slab. It seems like a pretty effective system for constructing walls.

I think the house was built around 1910. I reckon that the partition wall was probably put in during a later refurb. The houses used to have outside toilets, so perhaps the wall was put in to create the space for an internal bathroom? Here are some photos. Maybe these will shed some light.

Hello. I have a partition wall in my house that I have started to take down but am puzzled over what material it is. I am hoping it is nothing too sinister (I.E. asbestos) Here are the details: 1. the panels are approximately 36"wide x 12"high x 3" thick. 2. they are...
