Remote UPS mode:

According to fire safety regulation, UPS power supply must equip with remote UPS function. So the power supply unit can

be linked to the fire alarm system, user's system will be able to detect the status of PIN3 and PIN4 LAD-360xU with UART

communication. When PIN 3 and PIN 4 is shorted, the power supply will enter remote UPS mode, therefore the UPS mode

will be active and the status signal will also send to the fire alarm system for indication. Personal or the system can use the

signal as trigger threshold for other alarm systems to decide when and how to enter the emergency sequence. Under this

condition, BAT. UVP alarm and protection are still active.
