4.2.8.6 Connecting a Doorphone
2 doorphone types are available, depending on the operating mode used:
•
Type A: relay-controlled doorphones (e.g. NPTT)
•
Type B: doorphones controlled by MF Q23 signals requiring a SLI interface (e.g. TELEMINI and
UNIVERSAL DOORPHONE)
The doorphone interface comprises an intercom and an optional latch powered by the mains supply
through a SELV (Safety Extra Low Voltage) transformer.
It is connected via the DOORPHA and DOORPHB outputs (control contacts open when idle) of the
DOORPHONE connector.

The system also allows for the connection of 2 doorphones without latch.
4.2.8.6.2 Connecting a Telemini and Universal Doorphone
These doorphones require the use of a Z station interface.
•
Several of these doorphones can be connected to the system; the limit is determined by the
maximum number of analog stations the system can support.
