4.2.7.6 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 an 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.
