BELLSET No. 44
|Improved version of Bellset No. 39.
This Bellset consists of a base unit, complete with switch unit, buzzer, two push buttons and indicator flap. This combination does not contain a bell, so a bell was always fitted externally.
Two batteries called Cells, Dry R40 (1.5v each) were supplied to power the intercom facility and buzzers. These were located in a Box, Battery No. 2, which was fitted close to the Bellset.
The Bellset can be used on Shared Service and PBX circuits with recall.
The press buttons and labels are stored inside the Bellset and fitted, as appropriate, on installation.
The Bellset could also provide secrecy when the extension was connected to the exchange line. This required the removal of links fitted between the Terminals 3 - 4 and the repositioning of the links connecting to terminals 34 and 31.
These were Mark 1 and Mark 2 (1954) models.
