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.
