4-Wire Interface with Call Signal

SKU: CLEEF-701M Categories: , , , ,

Description

Convert 2-wire to 4-wire with built-in hybrid null and wide-range level controls.

Besides being used as a visual indicator, Call Signaling can be used to trigger relays or functions in other intercom equipment.

For systems where only one or two partyline channels are needed, a rear dip switch selects the connection for the 4-wire audio and data as the RJ-45 jack instead of the DB-15.
