Fire Angel. This was left in our house when we bought it 3 years ago, quite an expensive item for peace of mind to wake someone very deaf who may not be alerted by the alarm. It couples strobing lights and a vibrating pad to place under the pillow.

I think I’ve found description on the internet

We have had no need to try it so not sure it will still work but be pleased if someone could make use of it. Please tell me who you need it for before I gift it and it is not to sell on.

I’m in Chesterfield, smoke! And pet free home not far from Walton hospital
