ACSI M1510MLR-LMR-L9070B-24V – Frequently Asked Questions

1) Will the ACSI M1520MLR work on a Schlage L9070 mortise lock?
That is exactly what it is built for. The M1520MLR LMR L9070B is a motorized latch retraction modification applied to a Schlage L9070 mortise lock, so the lock body itself is the L9070 and ACSI adds the motor and wiring to it. If your opening uses a different Schlage L-Series function, this is not the part, since the modification is tied to the L9070.
2) Does the ACSI 1500 Series electric mortise lock come fail safe or fail secure, and can I change it in the field?
Both, and you pick it on site. Fail safe and fail secure are field selectable on the motor controlled locks, so one unit covers either behavior. Fail safe means outside trim locks when power is applied and unlocks when power is removed, so the door unlocks on a power failure. Fail secure is the reverse: powered to unlock, locked when power drops. Stairtowers and egress paths usually drive that choice, so confirm which way your life safety plan calls for before you set it.
3) What voltage does the ACSI M1520 motorized mortise lock run on?
12 or 24 volts, AC or DC. The unit is ordered on a voltage option, either 12VAC/VDC or 24VAC/VDC, and each voltage is available in both the fail safe and fail secure configuration. It is continuous duty rated with low power consumption, so it can sit energized on an access control circuit all day without a duty cycle limit.
4) Does this ACSI electrified mortise lock report latch status back to the access control panel?
It does. The electrical configuration includes a latchbolt monitor, so the lock provides a signal on latchbolt position back to your panel or head end. That is what you want when the system has to prove a stairtower or controlled door actually relatched rather than just assuming the strike released. You will need to pull the monitor conductors along with the power pair when you spec the door cord or hinge transfer.
5) What do I have to specify when ordering the ACSI M1520MLR electric mortise lock?
Two things drive the order: the fail safe or fail secure configuration and the voltage, 12VAC/VDC or 24VAC/VDC. Those are the only two option axes, and all four combinations are offered. The lock is a lever trim mortise lockset, so the lever design and finish are part of the Schlage L9070 lock it is built on, and the cylinder is a separate line item on jobs like this.
6) Can this ACSI lock be tied into the fire alarm so the doors release on alarm?
Yes, the 1500 Series is built to interface with life safety systems, and that is the point of the field selectable fail safe setting. Set fail safe and dropping power on alarm unlocks the outside trim. Wire the lock power through a relay the alarm panel drops, and remember the choice of fail safe or fail secure has to match what the life safety drawings call for on that opening, not just what the access control integrator prefers.
7) Is the ACSI 1500 Series lock rated for commercial traffic or is it a residential product?
Commercial. The 1500 Series is a commercial electrified mortise lockset with lever trim, built on a mortise lock body rather than a cylindrical or tubular lock, and it is continuous duty rated for circuits that stay energized. Mortise construction is what institutional and multi-family facilities standardize on for stair and corridor doors that see constant use.
