The Valcom Noise Sensing Volume Control, part number V-9933A, is a self-contained device designed for integration into paging systems. This unit continuously monitors ambient noise levels within a designated area and automatically adjusts the volume output of connected paging speakers. It is intended for businesses and organizations that require consistent audibility for announcements in environments with fluctuating background noise, such as warehouses, manufacturing floors, or public spaces. By dynamically adapting speaker volume, the V-9933A helps ensure that pages are clear without being excessively loud during quiet periods. This device can be deployed one per zone or per specific noise area, addressing a common challenge of maintaining effective communication across varied operational settings.
The Valcom Noise Sensing Volume Control requires -24 Vdc at 100 mA for operation.
The V-9933A is compatible with existing twisted pair cables and can expand systems up to 96 zones when used with the V-2925A. It supports overall systems up to 360 zones.
This device uses standard CAT 3, 5, or 5E twisted pair cabling for connectivity.
The Valcom V-9933A measures 7.3 inches H x 4.7 inches W x 2.1 inches D (18.54 cm x 11.93 cm x 5.33 cm) and has a shipping weight of 1.1 lbs (0.50 kg).
