Carbon monoxide alarms

Should you be able to turn these off?

Mine went off early hours this morning and was advised to go and stay outside until emergency services arrived. They are an extremely piercing sound which disturbed neighbours too.

It was reading 15 so they checked all round and disconnected my gas. When they left the readings had dropped to 7. I felt a bit guilty when 2 appliances arrived but they assured me I had done the correct thing.

That's worrying - did you find out what it was?

For anyone else you can get a CO spray on ebay for test purposes

Not really but I only have a gas boiler and gas fire and the fire had not been on.The boiler is on a setting to come on twice a day for water only which had gone off at 8.30 pm.
Anyway tomorrow the boiler is being serviced and smoke tested, the fire serviced too then my gas can be reconnected hopefully.
