System Components SB-NCM Module
3.6 SB-NCM Module
This module can control eight 250mA outputs for controlling notification appliances (visual/acous-
tic signals). The current of the 8 outputs is limited by self-resetting fuses. Line control is carried out
by inverting the polarity. This also makes it possible to control electronic devices having low Cur-
rent consumption in stand by.
Notes:
Line control occurs only when the outputs are inactive.
Synchronization of devices between zones or within a zone is not permissible using this module.
