Description

BS 5839-1 and other standards require visual signals that form part of the fire system to be clearly distinguishable from other signals.

A label, that is legible when stood on the floor, with the word ‘FIRE’ is often used to distinguish visual alarms. The Cranford base labels fit the VTG, VXB and VTB products via the same mounting screws as the main product.
