RE: Central Locking

["Rodney Hall" <rmh@xxxxxxxxxx>]

Why don't you use fail locked and use battery back-up?

I have all external access locked this way, including the garage door. On
test, one set (garage door, accidentally!) lasted 3 months without mains! I
use Paxton access with weatherproof keypads http://www.paxton-access.co.uk
