There doesn't appear to be an ionisation detector available for the Ei Electronics (Aico) 3000 series alarm range. Or does anyone know of one?

Basically there was a house which was a HMO at one time, but was converted to a single family rented property. For some reason the fire alarm panel was disconnected and the system was replaced with standard domestic-type detectors. Unfortunately there is a whole mix of brands, with many heads missing or damaged. So every head will just need to be replaced. I had intended to fit ionisation detectors in the rooms with opticals everywhere else (bar obviously heat detector in the kitchen).

just fit opticals (except for kitchen. ionisations are a pain in the arse for false alarms. burn toast in kitchen, bedroom detector alarms.

I believe manufacturers of Part 6 devices are moving away from them for several reasons one being people choose optical over ionization due to false activation plus ionization contain radioactive materials banned in many countries.

Yes sorry, I notice I wrote "intended to fit ionisation in the rooms" - I had intended to write bedrooms!

So to clarify there are 4 bedrooms, which I had intended to fit ionisations in.

Between escape routes and main habitable room, there are 6 opticals.

And one heat (in the kitchen).

Aico Ionisation Smoke alarm is the Ei141RC, however in the 3000 series the Ei3016 Optical smoke alarm is an infrared LED and photo-diode Receiver.

The Ei3024 is a heat sensor and Optical sensor that will trigger from smoke alone.

I'm sensing the best solution will be to substitute ionisation detectors in bedrooms for multi-sensors. EI141RC appears to be discontinued with only existing stock remaining so far as I can tell. Unfortunately this will obviously push the cost of the detectors up further.

I have found in the past that multi buys on e-bay are OK, but the units are about three months into the ten year life period, if that does not bother you then the less expensive Ei3016 is probably the best bet as a Optical Smoke Alarm, if you are fitting these in the same place as the originals, do they have mains power to them already?

Yes all mains wired with wired interlink (in any I checked anyway).

But the 11 detectors are going to cost the landlord somewhere in the region of £600 in parts alone.

I have found my local wholesalers still have stocks of the 141RC ionisation alarms.
However, these are classed as D2, as they have a user changeable battery. BS5839 part 6 recommends grade D1, with tamper proof rechargeable batteries, if the property is to be rented. The Aico 161RC is ionisation, grade D1, but harder to get hold of.

This information is all in the Aico Handybook App, which is very, well erm.... handy.
