Fire damper mini-controller BKSYS TECHNICAL DOCUMENTATION Safety-related notes | Areas of application SAFETY-RELATED NOTES The connection to the electric mains must be performed by a qualified electrician. The transformers used for power supply must meet the requirements according to DIN EN 61558 / VDE 570 part 2-6. A corresponding fuse protection must be available on the mains side. The BKSYS fire damper mini-controller by SCHAKO controls and regulates up to 16 motorised fire dampers (24V AC/DC) or up to 32 fire dampers with a limit switch. The basic module BKSYS-GM1 can be easily extended...

Fire damper mini-controller BKSYS TECHNICAL DOCUMENTATION System components | SYSTEM COMPONENTS EXPANSION MODULE BKSYS-EM1 BASIC MODULE BKSYS-GM1 The power supply of all connected expansion modules and spring return actuators is performed via the basic module BKSYS-GM1. Furthermore, the basic module BKSYS-GM1 controls and regulates the potential-free inputs and outputs, integrates the smoke detectors and forwards the data via the ring buffer and RS232/USB interface to the user. All functions in the basic module BKSYS-GM1 have been designed for maximum simplicity and maximum safety at the...

Fire damper mini-controller BKSYS TECHNICAL DOCUMENTATION | Configuration FUNCTIONAL TEST The test run serves for functional check of the connected spring return actuators. One button each on the BKSYS basic and expansion modules is used to start the functional test. The spring return actuators assigned to the corresponding basic or expansion module close the fire dampers. After reaching the Closed position, the spring return actuators open the fire dampers again. During this functional test, the LEDs assigned to the spring return actuators are flashing. The same functional test can also be...

Fire damper mini-controller BKSYS TECHNICAL DOCUMENTATION | Commissioning sion modules BKSYS-EM1 (terminal X2 to BKSYS-GM1 and terminal X1 to BKSYS-EM1). If a smoke detector triggers an alarm, then this command is limited only to the connected module. Thus, only the motorised fire dampers connected to the corresponding module will be closed. TERMINAL ASSIGNMENT OF EXPANSION MODULE BKSYS-EM1 08. Select the setting in the ALARM DELAY checkbox: The set time indicates how long the fault output is disabled for maintenance purposes. Once the time has elapsed, the set value is reset to 0 minutes....
