The SAR4 and SAR5 can be connected to a telecommunications access line or separate control voltage source (AC/DC) and are activated by the call voltage or control voltage. The SAR reacts either only to the call voltage or to the control voltage. It activates an external signal emitter with its own or separate power supply (e.g. bell, horn, or lamp).
