C.B. WALL PATTERN
Flameproof C.B. telephone

Specially designed for outdoor use, and is particularly suitable for railway and shipyards, docks or chemical factories, petroleum refineries and other places where it may be exposed to flammable vapours or atmospheres. The ordinary type of instrument is unsuitable in these cases, both electrically and mechanically.

The cast-iron case is watertight and the inner door is fastened by screw locks requiring a special key for opening. The outer door effectually protects the micro-telephone when not in use and the drip-proof cowl fitted on top protects the ringer gongs, without deadening the sound. The incoming lines are disconnected by an isolating switch which is operated when the inner door is opened. All the apparatus, coils and wiring are specially treated to prevent detrimental atmospheric effects. A terminal chamber to accommodate external wiring is provided, normally one of two types to take either armoured cable with three sealing glands, or with three bosses tapped for 3/4 conduit. If required a terminal chamber suitable for mineral insulated cable can also be supplied.
