arrangement
Fig 2. Centralized 240 channel annunciator system with field contact doubling outputs.
The maximum size of the alarm system is 35
annunciator modules with 16 channels each, i.e.
a total of 560 channels.
By means of the SACO 148D4 or another highet
level system and a local printer event reports with
time markings can be listed and/or the informa-
tion can be forwarded to other systems.
Without the relay unit SACO 128R4 the annun-
ciator system comprises 16 builtin, freely group-
able reflash relays per subrack. By using the relay
unit with max. 128 relays the necessary number
of contact multiplyings, parallel lamp outputs and
group reflashes is provided for. Further, each out-
put allows grouping of signals.
