Fire damper communication system with safety ring bus, Modbus interface and BACnet

Intelligent building automation makes a significant contribution to fire protection and requires extensive know-how for the professional implementation of valid standards, laws, directives and regulations. DIGICONTROL offers innovative and safe solutions and is your competent partner for practice-oriented fire protection.

The DIGICONTROL BKOM system is designed for safe monitoring and control as well as for automatic test runs of fire dampers (BSK) with motorised actuators. It consists of a central module ems4.BKZ1E (in redundant design comprising two central modules), which communicates via a safety ring bus with up to 100 fire damper modules ems4.DEA2I, which can each connect a fire damper.

System topology

Added value

High system availability due to BKOM ring bus topology
If a device or a connection is malfunctioning, the fire damper system continues to operate thanks to the ring bus topology. Furthermore, the used CAN technology guarantees fast responses and excellent performance. A redundant design of the central module (optional) provides even more safety.

Fast analysis and diagnosis of faults
The central module uses the ring bus topology to detect and locate defective fire damper motors and interrupted or short-circuited bus connections. It provides the operator with a detailed fault description including the location of the fault source in case of a fault.

Due to the communication of the fire damper via a data bus, fewer electrical cables and a smaller cross-section are required. The simple commissioning also saves time and costs.

Simple, semi-automated and time-saving commissioning
The addressing of the fire damper modules and the optimisation of the data transfer are automated. The commissioning of the ring bus system is supported by diagnostic tools.

Integration in BACnet networks and automation station types with Modbus
The BKOM system enables the secure and trouble-free integration into BACnet networks. The Modbus interface, which is integrated in the central module, enables the BKOM system to be used as an independent unit within all automation systems, which are equipped with a Modbus interface. In this way, the BKOM system can also be used for applications other than DIGICONTROL systems.



CAN-Central Module for Safety Ring Bus System

The module ems4.BKZ1E is the intelligent central module for a safety ring bus system for connecting e.g. fire damper modules for motor actuators and other ring bus compatible I/O modules.


CAN Field Bus Fire Damper Module for Safety Ring Bus System
