VTB Spatial Sounder/Beacon EN54-3 Approved 24Vdc

Product Overview

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. Both the sounder and beacon functions are fully synchronised. The product can also be used as a beacon only which is easily selected by a DIL switch at the time of installation.
