Product Description

The ALPHA COMMUNICATIONS CDL118B is a combination indicator light and buzzer unit designed for intercom systems operating at 24 volts DC. It mounts in a standard 2-gang wall box, making it compatible with common low-voltage installation practices. The CDL118B signals both visually and audibly, giving building occupants a clear alert when the intercom is activated.
