The LQ Series consists of compact LQ boxes and rack-mounted LQ-R panels, available in 2-, 4- or 8-port versions. The partyline ports are Clear-Com and RTS compatible. Two standalone partyline intercom circuits can easily be constructed by connecting two partyline ports. The 4-wire ports can interconnect with devices, such as analog ports of any matrix intercom system, analog telephone circuits, two-way radio gateways and audio consoles. A maximum of six LQ Series IP devices can be linked together in any 2-, 4-wire or 4-wire with GPIO combination.
