Von Duprin PS914 – Frequently Asked Questions

1) Will the Von Duprin PS914 power supply run both 12 VDC and 24 VDC electrified hardware?
The PS914 output is field-selectable between 12 VDC and 24 VDC, so you set it at the board during installation rather than ordering a voltage-specific unit. That matters when you are mixing hardware: a 24 VDC electric latch retraction device and a 12 VDC strike cannot share one PS914 output, because the whole supply is set to one voltage at a time. Pick the voltage your load needs and size the rest of the opening around it.
2) How many electric strikes or latch retraction devices can a 4A power supply handle?
The PS914 delivers 4A continuous, so add up the continuous draw of every device on it and stay under 4A. Its 16A inrush capacity is the more important number for motorized latch retraction and solenoid strikes, which pull a large startup surge for a fraction of a second before settling to a low holding current. That 16A headroom is what keeps the supply from tripping when several devices fire at once on an egress signal.
3) What is the difference between the PS914 relay boards and the 8 fuse protected output board?
Two different jobs. The relay option boards (2 relay output, independently controlled relay, and 4 relay board with integrated logic) switch power on and off in response to an input, which is what you want when access control needs to release or retract hardware. The 8 fuse TC protected output board does not switch anything; it splits the supply into eight individually protected circuits so a short at one opening does not take down the other seven. On a large job with many always-powered locks, you often want distribution. On a controlled opening, you want a relay board.
4) Do I need the FA version of the PS914 board to drop power on a fire alarm?
Yes, if the panel signal has to release the hardware. Boards are ordered either plain or with FA: 2 relay output with FA, independently controlled relays with FA, 4 relay board integrated logic with FA, 8 fuse protected outputs with FA, and a fire alarm relay only board if the alarm interface is all you need. Without an FA board there is no fire alarm input on the supply, and retrofitting one later means buying the board again. Decide this at order time with the fire alarm contractor.
5) Can I order a Von Duprin PS914 with battery backup so the doors stay powered in an outage?
Battery backup is a yes/no option on the PS914 and it pairs with every board choice, including the bare supply with no distribution board. Order it as Yes and the backup kit comes with the unit. If you order No and later decide you need it, you are adding the kit as a separate purchase. On fail-secure electric strikes and access controlled openings, backup is what keeps the door under control when the power drops.
6) What is a key lock cover on a power supply and do I need one?
The key lock cover is a locking enclosure cover, ordered as Yes or No on the PS914, and it stops anyone from opening the cabinet and reaching the board or the voltage selector. In a school, a healthcare corridor, a multi-tenant lobby, or anywhere the supply is mounted in an accessible space rather than a locked electrical room, it is worth specifying. It is available with any board configuration and with or without the battery backup kit.
7) Can I buy the PS914 as just the base supply without any relay or distribution board?
Yes. The PS914 is orderable with the distribution board set to None, on its own or with the battery backup kit and the key lock cover. That is the right configuration when the access control panel already has its own relay outputs and you only need clean, regulated 12 or 24 VDC power feeding it. Add a board only when the switching or the circuit protection has to happen at the supply.
8) Is the Von Duprin PS914 rated for commercial use or is it a light duty supply?
Grade 1 and commercial rated. That is the highest ANSI/BHMA duty designation for door hardware, and it is why the PS914 shows up on office buildings, schools, hospitals, and government facilities rather than light residential work. If you are specifying to a commercial hardware schedule, this meets a Grade 1 call-out.
9) I need independent control of two openings from one power supply. Which PS914 option does that?
Order the independently controlled relay board, available with or without FA and with or without battery backup. Each relay is switched separately, so one card reader can release one opening while the other stays secure off the same PS914. By contrast the plain 2 relay board output gives you two switched outputs without that independent control logic, and the 4 relay board carries integrated logic for more complex sequencing.
10) I am standardizing power supplies across a building. Can one PS914 configuration cover different openings?
Within limits. The PS914 base unit is the same across all forty ordering combinations, so a facility can standardize on one supply and vary only the board, the backup kit, and the cover per location. What does not vary within a single unit is voltage: it is set to 12 or 24 VDC for the whole supply. Buildings that mix 12 and 24 VDC hardware end up with two groups of PS914 units set differently, not one setting for everything.
