Introduction
The sounders provide the low frequencies required to conform to
BS5839 Pt. 1. The dc versions are polarised for line monitoring and
feature a second tone option via a third wire. The sounder beacon
combined units and the flange mount unit are two tone only using tones
3 and 14 for 24V and tones 5 and 4 for the 12V unit.
