FAQs
How many doors or devices can the PS440B power?
The PS440B delivers 24VDC at 4 amps across 4 individually PTC-fused outputs, twice the output count and current of the PS220B. That capacity supports mid-sized installations, such as four doors with lighter-draw devices or fewer doors with higher-draw hardware like maglocks or motorized exit devices.
Does the PS440B include battery backup, and why does that matter?
Yes, the PS440B accepts backup batteries (sold separately) so access-controlled doors keep functioning during a power outage, which is important for fail-safe locking hardware that codes require to either release or stay operational when utility power is lost. This makes it suited to multi-door projects where continuity of access during an outage is a design requirement.
What's the difference between the PS440B and the PS220B?
The PS440B doubles the PS220B's capacity, going from 2 outputs at 2 amps to 4 outputs at 4 amps, while keeping the same battery backup capability. Choose the PS440B when a project has more doors or higher-draw devices than a 2-output unit can handle.
Is the PS440B UL listed for life-safety applications?
Yes, it's UL Listed to UL 294, 6th Edition, the Standard for Access Control System Units, and includes a fire alarm link and an interface relay that isolates locking device current from the control switch.
What hardware can the PS440B run?
It's designed for solenoid and motor-driven exit devices, electric locks, and electric strikes, with surge suppression on both fail-safe and fail-secure outputs so a single unit can serve mixed lock types across its 4 outputs.
