5.19.4.3 Connecting external alarm indicators
The points below apply to connecting external alarm indicators:
● If the external alarm indicator is connected to only one individual detector, there
is no limitation.
● If only original AnalogPLUS detectors and FDOOT241-A3 with base adapter
FDB241 are used, there is no limitation.
● If several FDOOT241-A3 are merged with detector base FDB22x on an
external alarm indicator in Sinteso, external alarm indicator FDAI9x must be
used.
