Features

Linking 2-wire Intercom Systems

• The general purpose of the Clear-Com LQ interfaces is to connect and route signals from multiple intercom systems and audio devices from point-to-point or point-to-multi-point, virtually anywhere over the secure IP network. 2-wire partyline devices such as Clear-Com’s or any industry-standard intercom system break away from traditional cabling and take advantage of available IP infrastructure for connecting to other 2-wire systems.

Extending Existing Intercom Systems

• Need to add an intercom user position across campus and in the next town? Just interface your existing 2-wire partyline system, regardless of brand, with LQ-R2W4 devices. Place the same LQ device at the desired position, then connect the 2-wire beltpack directly into the LQ device. Once devices are networked together with the Core Configuration Manager, the open communication link between these devices will allow everyone on the intercom network to talk or listen, depend on the configuration.
