VTB-32EM Marine Approved – Spatial Sounder/Beacon 24Vdc

Product Overview

The newly introduced range of VTB-32EM Marine Equipment Directive (MED) and American Bureau of Shipping (ABS) Type approved spatial sounder/beacons have been developed, tested and manufactured for use in the Maritime industry. To meet the demands of this harsh operating environment, and to ensure full compatibility with MED and ABS, these sounder/beacons have undergone additional independent EMC, vibration and salt mist testing to ensure they are fit for purpose.

The VTB-32EM spatial sounder/beacons have been designed to operate with marine approved fire alarm control panels and are supplied, as standard, with 32 selectable tones, two of which are the “Marine General Alarm” and the International Marine Organisation (IMO) “Code 2 Continuous” signals. The VTB-32EM also has a beacon-only feature. The devices have a changeover facility, allowing the selection of “Alert” and “Evacuation” tones when installed using three-core cable. The VTB-32EM tones provide the most common sound patterns and frequencies, and both the  sounder and beacon are fully synchronised.
