The Power Supply 2.5A is an auxiliary power supply that you can use to power alarm devices if your alarm control panel doesn’t have enough auxiliary power output. This power supply converts low voltage AC power input into a selectable 6VDC, 12VDC, or 24VDC power output. This gives you a continuous power supply current of 2.5A.

The power supply also has a charging circuit with a maximum charge rate of 350mA so that you can connect a backup battery. Additionally, with a battery back up connected, this power supply will automatically switch to standby backup battery continue to work during a power outage.

The Power Supply 2.5A also has convenient LED diagnostics to provide visual indication of how the power supply is operating.

There are (6) terminals along the bottom of the Power Supply 2.5A power supply. The (2) terminals on the left side are for (+) and (-) DC, which you will use to connect to your alarm device. The middle (2) terminals are for (+) and (-) BAT, and you should connect the red battery lead to the BAT (+) terminal and the black battery lead to the BAT (-) terminal. Plus, the other end of the battery leads have spade connectors which slide onto the battery terminals on the  sealed lead acid battery. Finally, the last (2) terminals marked ‘AC’ are for connecting your AC transformer.
