Yes. The FA6720-R is the direct replacement for the discontinued HT-630 heat alarm. It uses the same baseplate, so you can swap units without drilling new holes. The FA6720-R offers upgrades including a 10-year sealed lithium battery, thermistor sensor technology, quiet self-test and Sleep Easy mode. If your HT-630 is chirping continuously, it has reached end of life and should be replaced with the FA6720-R.
