This signal input interface mainly to be used in middle size fire fighting project. Feature:
★ The bus repeater is connected on 2-bus, set with one addressable code. The control bus is no-polarized, but the power bus is polarized.
★ LD6806E bus repeater need DC24V power supply, polarized.
★ When the load current exceed 100 mA or the line overlong and the total resistance exceed 50 Ω, need one repeater. After that the load current ≤ 100 mA (the power current loaded on the detector, interface and interlock module, etc)
★ With the short circuit isolation function, the repeater will insulated the malfunction circuitry section while the detector or circuitry in short. This action has no affection to the alarming main line and other equipments that before repeater (such as detectors, module and area display).
