The Bosch FLM-420-NAC-S Notification Appliance Circuit Module is an advanced interface designed for the monitoring and activation of notification appliances within Local Security Network (LSN) systems. This module allows for the seamless integration of acoustic and optical signal devices, such as sirens, into fire alarm control panels.Key Features:Rotary switches for automatic or manual address settingControl of notification appliance circuits via polarity reversalSynchronized activation of all connected notification devices10 selectable output signal types via LSNMaintains LSN loop functionality during cable breaks or short circuits with built-in short-circuit isolatorsSurface-mountable housingModule Functions:Activation of notification appliances in alarm conditionsMonitoring of notification appliance circuitsExternal power supply monitoringStatus indication via LEDsUpon activation, all notification devices connected to the FLM-420-NAC-S are synchronized through the LSN module. Control of the notification appliance circuit is achieved through polarity reversal, with the NAC zone status indicated by red and green LEDs. The rotary switch allows for easy selection between automatic and manual addressing, with or without automatic detection.LSN Functions:Built-in isolators ensure continued operation in case of short circuits or line breaksFault information is transmitted to the fire alarm control panel
