Bosch FLM-420-NAC-S Surface-mounted Signal Device Interface Module, 1 Monitored Output Line

Product Code: FLM-420-NAC-S
Module & IsolatorAdresli

FLM-420-NAC-S is a signal device interface module that controls conventional siren and flasher lines via addressed loop. The output line is driven by pole switching; since it is monitored when idle, a broken warning cable is detected before the alarm. Warning devices connected to the module are triggered simultaneously; ten separate output patterns can be selected from the data bus. The address can be manually set with a rotary switch, allowing sequential configuration during commissioning without computer connection.
