Connect onto terminal 4 only via pre resistor, otherwise the LED could
be destroyed.
All current Bosch fire detectors are equipped with an internal resistor
to restrict current consumption.

CAUTION!
If the current consumption for the connected detector exceeds 20 mA, it can lead to the
malfunction of or damage to the MPA External Detector Alarm Display. You should restrict the
maximum detector current consumption to 20 mA to avoid damaging the FAA-420-RI.
NOTICE!
The cable length between the detector and the MPA must not exceed 3 m when connected by
an unscreened cable.
