Kidde Airsense 9-30855-38 EN 54-4 Approved, 24 V 4 A + 1.5 A Intelligent Power Supply

The 9-30852-38 is a fully featured 24V EN54-4 approved power supply ideal for use in fire system applications. The output current is split between the load and charging the batteries. It features intelligent battery charging, monitoring and signalling, while providing deep discharge protection to prevent premature battery failure when operating from standby for extended periods.

The power supply is supplied in a self-contained, wall mounting box that can also house 38 Ah batteries (not included). Selection of the battery size is easy with the use of a jumper. Similarly a jumper is used to select between dual-path or two individual outputs.

With this feature mission critical applications can be powered, ensuring redundancy in the supply of 24 V to the load.

On the front of the unit, 6 LEDs indicated the status of the power supply. To aid with the interpretation of the meaning of the LEDs, a legend is used on the front of the unit. Additionally there is also a diagnostics LED, that with different flash patterns indicated even more detailed information.

A potential-free contact is used to signal faults due to output failure, battery fault, charger fault or internal fault. A second potential-free contact signals the loss of mains power.
