Cranford Controls VTB Spatial Sounder & Beacon


SKU: a6b7e7367e14 Category: Brand:


The VTB 24Vdc sounder beacon is part of the VTG family of products designed for use with conventional fire alarm systems including two wire (SAV-WIRE®) and other general 24Vdc applications.

The sounder function, like all VTG products, comes as standard with 32 tones. The beacon function has been designed for maximum all-round visibility, coupled with low power consumption utilising an array of energy efficient LEDs. The sounder function features a two-stage alarm override which is activated by a third negative wire from the fire panel.
