SB-SIM/GM Module
3.3 SB-SIM/GM Module
This module can control eight balanced inputs for conventional sensors with safety-related func-
tions able to control possible power voltage dispersions. All the channels can be individually reset
and are tested every 10 seconds during operation. It is used to control conventional fire detectors
and NO/NC contacts in general. This module must be used each time a local power supply is used
to power the Safety Bus modules. The first two module inputs must be configured to signal the pri-
mary and secondary power supply failure to the panel. Furthermore, the module detects ground dis-
persion of the power supply circuits and of all the secondary I/O circuits. Positive or negative
ground dispersion is indicated locally on both the module and the panel.
