You mean the external sounder? Depends if it's wireless and how it is

get a new SAB. Texecom Odyssey series are a good bet.

Don't fancy a wireless external sounder. Surely they should be pretty
inaccessible, so difficult to change the battery? And you'd need a fair
old battery to give a decently loud siren for 20 minutes?
