The SCHNEIDER BMC-1000 motor controller can operate up to four flap drives (fire protection and/or smoke removal flaps in random array). Switching the motorised flaps on and off is time controlled. The motor current is monitored for permitted levels at the same time. An appropriate fault signal is issued in the bus network if there are any malfunctions. An integrated test function enables easy visual and functional examination of the flap drives in the system. Corresponding LED's signal the status of the respective motor drives.

SCHNEIDER BAM-1000 alarm modules can be mounted on site wherever required. They are supplied in a surface-mounting housing design (150 x 150 x 50 mm). Along with direct smoke and fire alarms, functions also include the possibility of an integrated flap drive test. Unrestricted configuration of network variables make it possible to assign any number of flap drives to one or more smoke or fire alarms. A fire alarm in an alarm module automatically triggers the monitored closing process of any number of assigned fire protection flaps. This signal is received by the building services management system at the same time and the motor controller releases the appropriate signal to the LON network upon completed closure. The building services management computer initiates the appropriate action and also checks all incoming telegrams for plausibility. This concept guarantees a very high standard of safety for the user.

The SCHNEIDER BTM-1000 separating module monitors the ring-bus line for uninterrupted operation and ensures bus termination. If the bus line is interrupted at any point, the separating module localises the line fault between two stations, sends an appropriate signal to the LON network and closes the ring-bus line. The function of the complete network is retained without restriction in this way.
