ACSI 1550K-MDV22 – Frequently Asked Questions

1) Will the ACSI 1550K-MDV22 kit work on a Von Duprin 22 Series exit device?
That's exactly what it's built for. The 1550K-MDV22 is a motorized latch retraction modification for Von Duprin 22 Series exit devices, and that is the only device family it covers. If your openings run Von Duprin 33A/35A or 98/99 instead, the 1550K-MDV is the kit for those. Sargent 80 and Arrow 1000/3000/4000 take the 1550K-MDS, Corbin Russwin ED4000/ED5000 and Yale 7000 take the 1550K-MDC, and Falcon 24/25 takes the 1550K-MDF. Ordering the wrong suffix gets you a kit that will not mount.
2) Does the ACSI 1550K-MDV22 include the exit device, or do I supply my own?
You supply the exit device. ACSI's model is that you send in (or already own) the Von Duprin 22, and the 1550K-MDV22 is the modification applied to it. It can be installed in the field or done at the factory. So budget the panic device separately, and plan on the power supply too, since motorized latch retraction is not a dry contact, it needs 24VDC behind it.
3) What power supply do I need for an ACSI motorized latch retraction kit on a Von Duprin 22?
It runs on 24VDC, and ACSI recommends its own Series 1400 power supplies for it. The leads are non-polarized, so you are not chasing polarity at the transfer hinge or door loop during hookup. Draw is low and the unit is continuous duty rated, which matters if the opening sits unlocked on a schedule for hours at a time rather than pulsing on a card read.
4) Can I use electric latch retraction on a fire rated door with a Von Duprin 22?
The 1550K-MDV22 modification is UL Listed for both panic and fire exit hardware, so it is not limited to non-rated openings the way mechanical dogging is. That is the practical reason to go motorized on a fire door: a fire exit device cannot be dogged mechanically, and this kit gives you the same held-retracted push-pull operation electrically while the assembly stays listed.
5) Does the ACSI 1550K-MDV22 give me electric dogging as well as latch retraction?
Both at once. The kit retracts the latch and dogs the device simultaneously, holding the push bar depressed, so the door goes to full push-pull free egress and free entry while energized. Drop the power and it reverts to latching. That is what you want for a storefront or lobby that runs unlocked during business hours and secures on a schedule.
6) What is the difference between motorized latch retraction and solenoid latch retraction on a Von Duprin device?
Both pull the latch back electrically, but the motor version is the quieter, lower-draw approach and is continuous duty rated, so it can hold retracted through a full business day without a heavy dedicated supply. ACSI's 1550K-MDV22 is the motorized modification for the Von Duprin 22. ACSI also builds a solenoid kit, the 1550K-VD, but that one is for Von Duprin 33/35 and 98/99 devices, not the 22. For a 22 Series opening, the motorized kit is the path.
7) Can an ACSI latch retraction kit be tied into the fire alarm so the doors relatch?
Yes, the 1550K series is built to interface with life-safety systems, so the retraction can be dropped on alarm and the exit device returns to latched. On-board diagnostic LEDs on the module let a tech confirm at the door whether the unit is seeing power and commanding, instead of guessing from the head of the frame. There's also an automatic retry, so a cycle that doesn't complete on the first attempt gets tried again rather than sitting failed.
8) Is ACSI motorized latch retraction available for rim, mortise, and vertical rod exit devices?
The 1550K modifications cover mortise, rim, concealed vertical rod, and surface vertical rod exit devices, so a pair of doors on vertical rods can be electrified the same way a single rim device can. The 1550K-MDV22 specifically is the Von Duprin 22 Series version. Match the kit suffix to the device brand and series you have on the opening, not to the latching type.
9) Is the ACSI 1550K-MDV22 a commercial grade product for a multi-family or institutional building?
It is a commercial product, part of ACSI's 1500 Series of electric latch retraction modifications, and it's UL Listed for panic and fire exit hardware. For a facility standardizing across many openings, the useful part is that the same 1500 Series approach and the same 24VDC Series 1400 power supplies carry across the other device brands in the line, so a building running Von Duprin 22 on some doors and Sargent 80 or Falcon 24 on others can be brought onto one electrical scheme with different kit suffixes.
