• For any fire alarm system which specifies EN 54-4 power supplies (e.g. BS 5839 code of practice), EN 12101 and AOV systems.
• These power supply units can be used in any fire alarm installation requiring a 24 V supply for operation.
• Indoor use only (IP30).

Suited for almost any fire alarm application, the power supply unit/ battery charger has been developed using the latest surface mount technology to provide a high efficiency switch mode power supply.

The power supply units are available in fully enclosed construction providing power and fault indication or alternatively in caged versions for mounting into existing enclosures of various sizes to suit different battery capacities.

A universal AC input is provided on the 2.5 A and 5.0 A versions along with alternative enclosure sizes for all three options to support standby backup battery options.

Features and benefits:

• A range of power supply equipment with power output options to suit most applications.
• Universal AC input on the 2.5 A and 5.0 A versions.
• High efficiency switched mode power supplies.
• Compact 1.5 A, 2.5 A and 5.0 A versions.
• A range of power supply equipment with power output options to suit most applications.
• Can be used for communications and paging devices, and for connection to alarm receiving centres.
• Load-sharing on the 2.5 A and 5.0 A versions, supporting either rapid charging or brief high-current peak-loads.
• Self-resetting battery fuse protection on the 2.5 A and 5.0 A versions.
• LED indicators on the 2.5 A and 5.0 A versions provide quick status diagnostics of the power supply.
