Problem solved by replacing all alarms for aico models. I wont be using BRK again, even their technical helpline offered no idea's!

Manator Thanks for your reply, apologies if you misunderstood, i did replace all the alarms for a new set as mentioned in my post, Replacing again for a new set of aico alarms would be at my own cost because i cannot charge twice, i did explain to the customer that the original alarms were...

Hi All I have a very strange thing going on with a standard domestic set up of 1 heat detector in the kitchen & 3 smokes (1 on each level). All mains with mattery back up. Installed a new heat detector in the kitchen to interlink with the existing BRK smokes. All ok at first then after a...

Thanks for your replies. The required position is near the wash basin but outside of Zone 2 All circuits will be RCD protected so if the electrical apparatus is fixed to the wall with just the hose being extendable, should be OK. I wil contact TLC regarding the above unit to check. Thanks

definately no fault with the mains wiring as it is all located in the mains cupboard next to the CU. all connections have been checked for possible faults. The cable run is less than 2 metres from CU to LED drivers & dimming gear which are all connected in parallel from then on its all 24V...

Will look into this option but circuits are fed from new Hagar CU so could only do this if there is a cartridge fuse available as an mcb type module

Thanks for reply Did that already. Running load is 2.5amp. Start up surge will be just milliseconds so will not register on a meters display
