Another smoke detector question... Scottish property.

[littlespark]

Doing work in a house the other day, and noticed they didn't have any smoke detectors... (well, one.. and it was a small 9v thing)
So ive sent in an estimate for what's needed... 3 smokes, 1 heat and a couple of Co.

However.. its an old property in the village and there's a little add-on to the building. Might have once been a shop belonging the house... but now its a self contained rental property owned by the main house owners. I'm asking them via email if there is already smoke detectors in there.
The problem arises that there is an access door from one property to the other. Actually, a double door... There is a door on each side of the party wall, with slide bolt locks. But i do not think they are fire doors... they will be original to the house, and likely very solid... but not tested as a fire door.

Should the smoke detector system in the main house be linked to the granny annex on the side. Should they have a smoke detector located at the joining doorway to pick up any smoke coming through the door.... or leave them separate and hope they fit a proper fire door?

ISTR from an Aico event that you can have more than 12 units on a system using a mix of hardwire and radio linked units

Yes, but in total 12 radio units… be that detectors, wall mounted test buttons or radio modules in an otherwise mains powered hardwired detector- acting as a gateway between wired, and wireless

The way it was put you could have 2 groups of radio linked equipment linked by a hardwire link thus exceeding 12 units

That got me thinking, if you house code eleven units to a Aico Ei450 Radiolink+ Control and Hush Switch, can you link another eleven to that unit as the twelfth, i.e. link a different eleven together and just link one of them to the switch? academic question.

Possibly not.

I see what others are saying. You can have 12 units on one house code, another 12 on a different house code, and a hardwired link inbetween… such as 2 radio module bases.

I thought it made no difference if the unit is hardware linked or radio linked it still has to be house coded?

Each one of the radio base's is part of the overall linking so only eleven units can be house coded, if indeed twelve is the limit.

How big? Was it hardwired?
I think there’s a limit of 12 units on an Aico Radiolink…

Similar to how Ferg described it. It was the limit of the Aico system. Blended mains and battery units. 1 large house the could be split into 2. family live one side in the summer to rent out the other side to tourists.

Just re-read this thread again and had the following thought, if the house was a set of apartments you would not hesitate to link all the alarms for each apartment together, same for a block of flats.
