Valcom's VIP-148AL-GY, IP High-Efficiency Horn with Long Line Extender, enables a two-way, handsfree voice access to a single location over an IP-based network. This allows a page zone extension anywhere on the network that extends your coverage area. The IP Talkback Horn is suitable for paging, broadcasting emergency alerts and tones in areas that have moderate to high noise environments. The sturdy construction allows it to be mounted to a wall or electrical box and includes a "C" clamp for "I" Beam mounting.
