FAQs
Why does an access control power supply need battery backup?
Battery backup keeps electrified locks and access control functioning during a power outage, which matters because fire and life-safety codes require fail-safe locks to either unlock on power loss or maintain controlled access through a backup power source. The PS220B accepts backup batteries (sold separately) so a secured door isn't left completely without power when utility power drops.
How many doors can the PS220B power?
The PS220B provides the same capacity as the standard PS220: 24VDC at 2 amps across 2 PTC-fused outputs, plus 0.5A of continuous auxiliary power. It suits small single- or double-door installs where battery backup is also required for code compliance or continuity of access.
What's the difference between the PS220B and the PS220?
The PS220B adds battery backup to the identical 2-output, 2-amp @ 24VDC platform used by the PS220. If your project doesn't require backup power, the standard PS220 covers the same door capacity at a lower cost.
Is the PS220B UL listed?
Yes, it's UL Listed to UL 294, 6th Edition, the Standard for Access Control System Units, and includes fire alarm link capability so it can integrate with a building's fire alarm system for compliant fail-safe lock operation.
What types of locks work with the PS220B?
It's built to power solenoid and motor-driven exit devices, electric locks, electric strikes, and electrified hinges, with surge suppression protecting both fail-safe and fail-secure outputs so either lock type can be wired to the same unit.
