Falcon MA531P DG 626 – Frequently Asked Questions

1) What is the Falcon MA531 apartment corridor lock designed for?
The MA531 is a Grade 1 keyed mortise lock with deadbolt designed for apartment and corridor applications. It provides secure access control with automatic locking when the door closes. The lock meets ANSI/BHMA Grade 1 standards for heavy-duty commercial use.
2) Is this lock compatible with standard door preparations?
Yes, the MA531 fits standard ANSI mortise lock preparations. It requires a 1-1/8" bore hole and mortise pocket in the door edge. Verify your door thickness and existing prep dimensions before ordering. Most apartment doors with existing mortise locks can accommodate this unit.
3) How do I determine the correct handing for this lock?
Stand on the side of the door where the hinges are not visible. If the door opens to your right, it's right-handed. If it opens to your left, it's left-handed. The MA531 is field-reversible, so you can adjust the handing during installation if needed.
4) What finishes are available for the Falcon MA531?
The MA531 is typically available in satin chrome, dark bronze, and bright brass finishes. The finish should match existing hardware in the building. Verify the specific finish option when ordering as availability may vary by supplier.
5) What does Grade 1 certification mean for this lock?
Grade 1 is the highest ANSI/BHMA security rating for door locks. It means the MA531 has passed rigorous testing for strength, durability, and cycle life. Grade 1 locks are required for high-security commercial applications and provide superior protection against forced entry.
6) Can this lock be keyed to match other locks in the building?
Yes, the MA531 can be keyed alike or made part of a master key system. Contact a locksmith to coordinate keying with existing building locks. The lock uses standard 5-pin cylinders that can be re-keyed as needed for apartment turnovers or security changes.
7) What accessories are available for the MA531?
Common accessories include cylinder guards, different trim styles, and matching exit devices. Check with the manufacturer for specific compatible accessories. Door reinforcement plates may also be recommended for high-traffic installations.
8) What are the basic installation requirements?
Installation requires standard mortise lock preparation tools and templates. The door must be properly aligned and have adequate thickness (typically 1-3/4" minimum). Follow manufacturer templates exactly for bore hole and mortise pocket dimensions. Professional installation is recommended for warranty compliance.
9) How do I maintain and adjust this mortise lock?
Regular maintenance includes lubricating the lock mechanism with graphite lubricant every 6 months. Check door alignment periodically as settling can affect operation. Adjust strike plate position if needed for proper latch engagement. Clean exterior surfaces with mild soap to prevent finish deterioration.
10) Are there similar models to consider?
Other Falcon mortise locks include different function variations like privacy, passage, or classroom functions. Consider the MA521 for different lever styles or other MA500 series locks for specific operational requirements.
11) What field conditions affect lock performance?
Extreme temperatures, high humidity, and salt air can affect lock operation and finish. Install door weatherstripping to protect the lock mechanism. In coastal areas, consider more frequent maintenance cleaning. Ensure proper door clearances to prevent binding during seasonal expansion.
12) What are the key measurements for this lock?
Standard measurements include 2-3/4" or 2-3/8" backset (verify which is needed), 1-1/8" bore diameter, and standard ANSI mortise pocket dimensions. The lock face is typically 1-1/4" wide. Confirm exact measurements with manufacturer specifications before cutting door preparations.
