Anyone know of a standalone flame detector ?



When I was shopping for smoke detectors and kitchen heat detector I
looked at these but decided the cost (GBP250 upwards) was not justified
as (i) they all seemed geared towards industrial events (eg gas and
gasoline) and (ii) it was unclear they would detect most kitchen events.
For example, what makes you think your (former) tea towel burnt with UV
emissions? I also never saw them recommended for domestic use.

If you are interested still just search for ultraviolet fire/flame
detectors.
