Features and/or Benefits
Linking 2-wire and 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. 2-wire partyline and 4-wire digital devices such as Clear-Com’s or any industry-standard intercom system can take advantage of available IP infrastructure for connecting to other 2-wire or 4-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, to a 4-wire solution such as Clear-Com’s HelixNet partyline or Agent-IC mobile app using the LQ-R2W4-4W4 devices. 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.
