Securitron B-12-5

12VDC battery for complimenting the BPS series power supplies.  Use in situations where you need your doors to always be locked, or when you have users who do not have a mechanical key backup to the door, and must be able to gain access with their code or card during a power failure.

• Order when your power supply is going to be next to door and you plan on setting the power supply voltage at 12VDC
