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 SIGMALOOP detectors and FDOOT241-A4 with base adapter
FDB241 are used, there is no limitation.
● If several FDOOT241-A4 are merged with Sinteso detector base FDB22x on an
external alarm indicator, the external alarm indicator FDAI9x must be used.
