Just done some more testing. If the intruder alarm is not set and smokes activate, the keypads sound, the external bell does not. If the intruder alarm is armed and the smokes sound - the keypads sound and the external bell DOES.
So do we only expect the external sounder to go off when smoke is detected if the system is armed??
