2.UART Communication Function (U version only)

360W Economical Security/Fire Alarm PSU with Battery Charger/UPS

L A D - 3 6 0 series

The power supply uploads various fault signals, power supply working status, single battery voltage, main voltage, output voltage and

output current to the controller through the UART, and changes the power supply working status according to the controller instructions.

For details,please refer to the user manual.

UPS Mode

Force start UPS mode:

According to fire safety regulation, UPS power supply must equip with force start UPS function. In case of emergency,

maintenance or testing, personal can active the UPS mode of by shorting PIN1 and PIN2 of LAD-360xU to ensure the energy

supply to the loads. When operating under UPS mode, the BAT. UVP alarm is still active, but the BAT. UVP protection will be

disable, therefore, the battery will be fully discharged until system shuts down.
