A fire alarm system power supply must be robust to ensure the safe continuity of fire detection. The Technoswitch EN54-4 certified power supply range provides reliable power when needed and continuously monitors total performance.

All power supplies are fitted with two independently protected AUX1 and AUX2 outputs, which provide a voltage of 24 V DC (±15%) and a total current output of either 3 A or 5 A, model-dependent.

The power supplies will automatically switch to battery power in case of power loss, providing an uninterrupted power source.

The power supplies are housed in a metal enclosure (red RAL 3001) with space for two 12 V maintenance-free lead-acid batteries. Battery sizes accommodated are 7 Ah or 17 Ah, model-dependent.
