KL-240SA is used for monitoring of peripheral devices of the fire extinguishing system with electrical activation. It works with a relay module (MR) needed for feeding of addressable devices.
Purpose
• Monitoring of connection line condition with addressable devices
• Monitoring of addressable devices condition
•Information exchange via HTTP MODBUS (Interface RS-485) with BKU-3200
• Receiving of commands from BKU-3200 and its transfer by addressable actuation devices
• Generating and transfer of command of power supply polarity switch of addressable devices to MR
• Receiving and transfer of a notification about failure of an external source of uninterrupted power supply to BKU-3200
