Honeywell 12 V 105 Ah battery for VA/PA emergency PSU (must be used in pairs)

The 581730 is a lead-free emergency power battery built to back up voice alarm and public address installations. Front-mounted terminals keep inspection and servicing straightforward within confined cabinet spaces, while a form factor suited to 19-inch racks lets it sit neatly alongside other rack-mounted equipment in standard equipment enclosures.

Rated at 12 V and 105 Ah, the unit is intended for the emergency power supplies found in PA and VA systems, where it is deployed as a matched pair to meet the required backup capacity. It supports the Gent D1 Voice Alarm and Public Address platform, including the emergency power supply units 581722 V-2 and 581723 V-4.

Because pairing and rack integration shape how the battery performs in service, wiring and connection details should be taken from the installation manual rather than assumed. Following that guidance helps the completed backup arrangement deliver dependable power during mains failure across safety-critical voice alarm and public address networks, supporting continuity of life-safety communication when primary supply is lost.
