ACSI 1550K-MDAEX – Frequently Asked Questions

1) What does an ACSI 1550K motorized latch retraction kit actually do to an exit device?
It converts a mechanical exit device into an electrically controlled one. The ACSI 1550K motor kit retracts the latch and dogs the device at the same time, holding the push bar depressed so the door pushes free until power is removed. That gives you remote release from a card reader, push button, or access control panel without changing the exterior trim.
2) What voltage and power supply does the ACSI 1550K motor latch retraction kit need?
24VDC. ACSI calls for its Series 1400 power supplies with these kits. The motor draws low current and is continuous duty rated, so it can sit energized through a long unlocked schedule without overheating. Leads are non-polarized, which takes the guesswork out of the field wiring.
3) Does this ACSI kit work on vertical rod and mortise exit devices or only rim devices?
All four types. ACSI builds the 1550K motor retraction modification for mortise, rim, concealed vertical rod, and surface vertical rod exit devices, so a pair of doors with SVR devices can be retracted electrically the same way a single rim device is.
4) My building has exit devices from several different manufacturers. Is there an ACSI motor kit for each one?
The 1550K family is built per device line, so you pick the suffix that matches the hardware on the door. Von Duprin 33A/35A and 98/99 take the 1550K-MDV, Von Duprin 22 the -MDV22, Corbin Russwin ED4000/ED5000 and Yale 7000 the -MDC, Dorma 9000 the -MDD, Hager 4500/4600 with PDQ 6200 and Stanley QED100/QED200/QED300 the -MDT, Sargent 80 and Arrow 1000/3000/4000 the -MDS, Precision 2000/5000 the -MDP, Falcon 24/25 the -MDF, Falcon 1690/1790 the -MDO, Design Hardware 1000 the -MDH, and Dorex 9500 the -MDX. There is also a 1550K-VD solenoid retraction kit for Von Duprin 33/35 and 98/99.
5) Do I buy the exit device from ACSI too, or send in the one I have?
You supply the exit device. ACSI supplies the UL Listed modification that goes into it, and the work can be done in the field or at the factory before the device ships. ACSI engineers also provide system design help and wiring diagrams for the install.
6) Is a motor latch retraction kit quieter than a solenoid kit on an exit device?
The motor versions are specified for quiet operation, which is why they get used on offices, healthcare, and libraries where a solenoid clack carries. ACSI also offers a solenoid retraction kit, the 1550K-VD for Von Duprin 33/35 and 98/99, if a solenoid is what the spec calls for.
7) How do I troubleshoot an ACSI motor latch retraction kit that will not pull the latch?
Start at the board. These kits carry on-board diagnostic LEDs that tell you whether the motor is getting its 24VDC signal, and the control has an automatic retry that will attempt the pull again if the first cycle stalls, which usually points to binding rods or a door under pressure rather than the electronics.
8) Is the ACSI 1500 Series latch retraction kit meant for commercial openings or will it work on a home?
Commercial. The 1500 Series motor retraction kits are commercial grade parts that modify panic and fire exit hardware, the kind of device you find on a means of egress door in an office, school, or multi-family building, not on residential entry hardware.
