The LBB1992/00 Voice Alarm Router is a versatile expansion unit for the Plena Voice Alarm System, designed to enhance system functionality by adding six zones and 12 input contacts. It supports dual-channel operation for simultaneous calls and background music (BGM), with compatibility for single-channel operation as well. The router integrates seamlessly with the Plena controller and amplifiers, providing robust and scalable solutions for public address and voice alarm systems.

Key Features

• Enhanced Zone Management:
