Device Overview
Providing Power
Each unit requires a 12VDC supply that can source at least 0.5A, but a 1A supply is always
recommended to ensure adequate power. (Note: Kits are supplied with a 12VDC/2.5A power supply)
If a Maglock, Door Strike, or other device is to be powered through an on-board wet relay, then the additional power required for those devices will need to be considered when selecting a power supply. A battery backup can be connected as
shown if required for the application.
Battery Backup Charging and UPS Functionality
The Controller and Remote Interfaces both provide a charging voltage for a 12V sealed lead acid
battery backup and they also have uninterruptable power supply (UPS) functionality. The UPS will
automatically switch to the battery backup whenever the 12VIN wall power goes out and will then
switch back to the 12VIN wall power when it returns.
