Product Description
ND12DEU-SPA-612 Schlage ND Series Cylindrical Lever Lock — Exit Lock, Electrically Unlocked (Fail Secure), Sparta Lever, Satin Bronze
Some doors have to stay locked from outside when the power drops. The ND12 in EU mode does that. With power on, the outside lever is unlocked. Take the power away, by a switch or an outage, and the outside lever locks. The inside lever is always free, so nobody gets held in. There is no key on this function.
This one is the Sparta lever on the Rhodes rose, in Satin Bronze. The latch is a deadlatch. Pick your backset in the dropdown: 2-3/4" is standard, 2-3/8" is the other choice. Measure from the door edge to the center of the bore before you order.

Pro-Installer FAQ
Q: What happens when the power goes out?
A: The outside lever locks. The inside lever still lets people out. If the door has to open from outside with no power, you want the EL version, which is fail safe.
Q: What voltage does it run on?
A: 12 or 24 volts DC. It detects which by itself. A switch on the chassis sets EL or EU in the field.
Q: Is this a Grade 1 lock?
A: Yes. The ND Series is ANSI/BHMA Certified A156.2 Grade 1, Series 4000. If the job does not call for Grade 1, Schlage's ALX Series is the Grade 2 cylindrical line.
