METZ CONNECT SAR 1 electrical relay White

The SAR 1 is connected to a telecommunications line and controlled by the call voltage.The SAR 1 only reacts to the call voltage, not to dialing pulses (IWV). It activates an external signal emitter with its own or separate power supply (e.g. bell, horn, or lamp) by means of a contact.The incorporated switch can be used to activate and deactivate external signals.
