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?

I would treat them as 2 separate residences If you have no guidance from the customer as to what they want.
its bad enough when you wake your own family at 7am with a toaster mishap but to do it to the holidaymakers may be seen as rude!!

Not sure of the rental laws in Scotland, but I would have thought smoke detectors are required in the let unit, and for peace of mind a tell tale in the main house.

This is an interesting one @littlespark
I'm thinking first of all about ignoring the connecting door, and just wondering if it would be a nice idea for the occupants in the main house to have notification of an alarm state in the annexe, maybe holiday visitors who left something switched on or a fire poorly tended etc. Thus,, not smoke leaking through the connecting doors, just a smoke or heat going off in the annexe, which, paired to the main house, would literally sound the alarm.
If you go the radio-linked route, you might be able to place a rogue unit in the annexe, as well as it having its own system, radio-linked or hard-wired.
Pairing the radio-linked type might be trickier, but hard-wired would be fairly straightforward? given there is a connecting door...

You can radio hose code the units in the annex to just one in the main house or to a switch unit in the main hose, and radio pair all the ones in the house together, but not to the annex.

Thanks Mike! That was what I was trying to say, but failed!

 

[littlespark]

Linking the systems aren’t going to be an issue. I’ve done plenty to know house coding on AICO.

I’m assuming the annexe already has detectors, or they wouldn’t be renting it.
Long term rent, not a holiday let. Has its own electric supply.

Main house will be battery units if they go for it.

Maybe keep them separate but have one located at joining door to pick up any smoke??

I agree, and didn't mean to suggest you were unversed in house coding, @littlespark
Maybe a luxury to "monitor" the annexe, but if you can...why not?

I’m flustered.
Been wrestling with caravan awning for past 3 hours!

To monitor the annexe? Open the door!

Now, now!!! You can't go opening doors into a rented property! LOL!
By the way...who won? You or the awning?

Well it’s up!

We’re at Barnard Castle…. I’ve found the Specsavers Dominic Cummings was looking for a couple years ago!

Did something similar last year albeit the property was a little larger. Owners lived one side and rented other side out. Highland council wanted 1 system all interconnected.

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

The last time I did something similar where BC (Highland Council) were involved they wanted them interlinked.

This is a relatively common set up in my neck of the woods for holiday lets and I always interlink them.

To my mind it's not really 2 separate dwellings but one where part of it is let out.

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.

 

[Mike Johnson]

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.
