Linking 4-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. LQ can link any 4-wire intercom systems such as Clear-Com’s Eclipse, Eclipse HX intercom system and Drake 4000 II panels over IP connections.

Extending Existing Intercom Systems

Need to add an intercom user position across campus and in the next town? Just interface your existing 4-wire intercom system, regardless of brand, with LQ-R4W8 devices. Place the appropriate LQ device at the desired position, then connect Clear-Com’s 4-wire system or panel 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.
