door to the 'HZ ' and ' ' monitor or telephone terminals.
The reproduced acoustic tones are different depending on their provenance, that allows the
user to distinguish where the call is made from. If during a conversation a call is made from
the apartment door, acoustic tones will be reproduced on the hanset to advise that someone
is calling.

The use of a SAR-90 relay will be required to activate a second camera and an internal

This push button can be used to activate other auxiliary devices, as the A1 terminal is used.
Usual applications are the surveillance of the elevator entrance, reception hall, ...
