StealthLock TP 150 keypad, open box industrial electronic hardware, no instructions

CompX Timberline Stealth Lock TP-150 keypad as shown. Open box, untested though never used. No installation instructions in this package, though you can probably find a PDF instruction sheet online.

I know very little about this, it's one of a number of high end electronic components out of an estate of a building contractor. Box has some soil and light wear from storage, contents are as shown and look good. The photos here show the exact unit you'll be receiving.
