Falcon 8500NL US10B LHR – Frequently Asked Questions

1) What is the Falcon 8500NL and is it a complete lock or just a part?
It's a replacement mortise lock component for Falcon exit device assemblies, not a standalone lockset. Falcon sells it as a purpose-built replacement for 8500NL series mortise lock assemblies used in exit device applications, so it goes into an existing Falcon device rather than into a bare door prep.
2) Does the Falcon 8500NL work on a right hand door?
No. This one is factory configured Left Hand Reverse (LHR), and it is not field-reversible per the product data. If your opening is right hand or right hand reverse, order the matching handed version instead. Confirm handing by standing outside the door: LHR means hinges on the left and the door swings toward you.
3) What does the Night Lock (NL) function actually do on an exit device?
Night Lock keeps the outside latch secured against entry while the inside pushbar still gives free egress at any time. So a school or office can lock the exterior side after hours without ever trapping anyone inside. If you need outside trim that allows entry with a key or lever during business hours, the NL function is the wrong configuration for that opening.
4) Can I use this Falcon mortise part to repair a rim exit device?
No. This is a mortise lock body component, so it only serves Falcon exit devices built on a mortise lock case. A rim device latches on the surface of the door face and uses an entirely different latch assembly, as does a surface or concealed vertical rod device. Match the part to the device type already in the door.
5) What finish does the Falcon 8500NL mortise lock part come in?
One finish: 613, Dark Oxidized Satin Bronze Oil Rubbed, applied at the factory. If the rest of your exit device hardware is 626 satin chrome or 630 stainless, the part will not visually match where it is exposed.
6) Is the 8500NL suitable for a high traffic commercial building or is it a residential part?
Strictly commercial. Falcon builds it to its commercial exit device standards for high-traffic institutional use, and typical applications include schools, healthcare facilities, government buildings, retail, warehouses, and multi-tenant residential corridors. It is not intended for residential entry locksets.
