The external power supply kit is designed to extend the autonomy of the fire detection and alarm system in the event of a main power failure.

Fire detection standards typically require that fire protection systems remain operational during power outages. To meet these requirements, a backup power system must be implemented—capable of supporting up to 72 Ah in standby mode, plus 30 minutes under alarm conditions. The FAD-AUXBAT kit enables the connection of up to two STX2410 (10A) external power supplies, allowing the system to support more than 130 Ah of battery capacity from a single control pane
