Extending a Mains Fire system - Domestic

[claret73]

Have been asked to look at adding an extra alarm for a customer as building control have told them they require an extra fitting. (I think they are renting out the house).Have done some Googling about & reading through my Aico Handybook, so have come up with this:

The Smokes are on their own circuit, hard wired, interconnected. They are Aico manufactured, so will replace 1 base unit with a Radiolink (quick thought, Would I still need to connect the Interconnect core, from 3 core cable to maintain a link from the previous feed? This unit is the 2nd in the radial circuit). For the additional unit, I'll fit a complete radiolink, which will sync with the existing hard wired, now replaced to Radiolink unit. The feed for this will be fed off an existing light point (closest is a Spot, will break in with a JB and spur to the Radiolink base)

As far as BS 5839 Part 6 goes, can I download a suitable certificate FOC? & would this require a Minor Works cert under Part P? Or is this classed as an additional lighting point - IE Coming off the Spot to feed the Radiolink base?

I'm not Part P, so if that's a Yes or I can't sign the Smoke Cert I'll pass it to my Contractor.
Cheers for any info

You dont spur fire alarms with radio link you need a base and a RC head , what i would do is remove one of the 3 core wires from a detector then from that detector to the new detector then back to the removed 3 core thus reconnecting the the detectors

Or, if you want to use wireless, ALL the detectors will need RC bases.

And then just dis the interlink.

i fitted 20 radio link bits of kit call points smokes etc and then sintra emailed me a cirt pm him to see if he can help.

Cheers Jason. Although looking at the AICO FAQ's, it seems I can remove just the one out of 3 units, replace that with a RadioLink & then fit a second RadioLink for the additional, thus having 2 wireless & 2 Hard Wired...Not fitted the Wireless so will talk to AICO

Nick. Might have mis quoted myself? When I said spur, I meant taking a feed from the lighting point to feed the additional RadioLink Base. It does need a L,N & E...I'll be replacing 1 Hard wired with a RadioLink Base & syncing that with the new additional Unit. That doesn;t require 3 core, just a 2c&E Feed off a Lighting Point (From what I gather from AICO Info)...

ah i see what you mean

It's always difficult to get across in words, much easier to see what you're looking at...Thanks anyhow for time
