Smoke alarm going off every time I reconnect it

Hello, My smoke alarm system went off this morning thanks to some smoke from the oven. I tried to stop it by pressing the 'Test & Hush' button on the alarm in the kitchen, but it didn't seem to work, so I removed the alarm from its bracket to stop it. I realise now I should have disconnected the mains supply to it first, and have also realised that that particular alarm in the system is a heat alarm (Aico Ei144) whereas the others are smoke alarms (Aico Ei141) - so presumably the alarm that detected the smoke was the not the one in the kitchen. Now, every time I reconnect the heat alarm in the kitchen to its bracket, it goes off - and I can't find any way to stop it. I've tried pressing the button, holding the button for 20 seconds, disconnecting the mains supply and changing the battery, changing the battery in the nearest smoke alarm... Can anyone offer any any advice or see what I'm doing wrong? Thank you very much in advance, Joe
