Loop Driver Module LDM

585343

Approval: EN 54-16

Loop driver module compatible with the VARIODYN ONE system. It allows the connection and monitoring of loop-style speaker circuits. Predisposed to be installed on a DIN rail (C bar). One LDM per Loop is required. RS-485 protocol for interfacing to the VARIODYN INC (Intelligent Network Controller).
