ACSI ACSI-8501M-PL-24VDC-626-RH – Frequently Asked Questions

1) What is the ACSI 8501M Gemini operator, and does it come with the lock body?
The 8501M is the Gemini operator module on its own, a replacement part rather than a complete locking assembly. It is the electric operator that drives the lock, sold as a component in ACSI's 8500 Series for commercial openings. If you are building a new opening from scratch you need the rest of the Gemini locking system too; if you are servicing an existing Gemini install and the operator has failed, this is the piece you swap.
2) Does the ACSI 8501M Gemini operator unlock or lock when the power drops?
Both behaviours are orderable. Fail-safe unlocks the door when power is removed, which is what you want on an egress path or anywhere the fire alarm has to release the opening. Fail-secure keeps the door locked with the power off, which suits a stockroom, IT closet or exterior door where losing power should not open the building. Pick the one that matches the life safety drawing for that opening, because it is a build option on the operator, not a field-changeable setting.
3) Is the ACSI 8501M Gemini operator handed, and how do I work out which hand to order?
Handing matters here, and it is fixed at the factory. Left hand and right hand are separate parts, so a right hand operator will not serve a left hand opening. Determine the hand from the outside of the door (the secure or key side) standing so the door swings away from you: hinges on the left is left hand, hinges on the right is right hand. Get it wrong and the part goes back.
4) What voltage does the ACSI 8501M Gemini operator run on, and does it take AC or DC?
24 volts, and the operator is offered for both 24VAC and 24VDC supply. That means an existing 24V transformer or a 24VDC access control power supply will drive it either way, but the AC and DC versions are ordered separately, so specify which one your panel or power supply puts out. If you are tying it to a card reader or an access control board, that is normally a filtered 24VDC output.
5) What do I have to specify when ordering an ACSI 8501M Gemini operator?
Four things settle the part number: fail-safe or fail-secure, handing (left or right), supply voltage (24VAC or 24VDC), and that is it on finish, since satin chrome 626 is the only one. Eight combinations exist in total. A property manager reordering a failed unit should pull the hand and the fail mode off the operator that came out rather than off the door schedule, because those two are what most often get mismatched on a replacement.
6) I need a replacement part for an access control opening. Is the ACSI 8501M the same kind of thing as a strike or an armature?
No, and they are not interchangeable. The 8501M is the powered operator inside the Gemini locking system, the part that actually drives the lock at 24 volts. A strike or armature accessory is passive mounting or catching hardware, such as the Securitron AOS armature offset strikes or the ABH 20020 standard door armature head assembly used with magnetic locks. If the failure on your opening is the electrified mechanism itself, the operator is the part; if it is what the lock pulls against, it is one of those.
