GEM GK450 User manual

  • Hello! I've reviewed the product details for the GIANNI electric strikes, specifically the GK450, GK450-ST, GK451, GK451-ST, GK480, GK480-ST, GK481, GK481-ST and GK485 models. This document provides information on their features, such as field-reversible fail-safe/fail-secure operation, high static strength, and the adjustable strike on the GK485 model. I'm ready to answer your questions about these electric strikes.
  • What type of locksets are these electric strikes designed for?
    Can the fail-safe/fail-secure operation be changed in the field?
    What is the static strength of these electric strikes?
    What is the adjustment range of GK485 electric strike?
The GK450/480 series ANSI electric strike is designed for use with cylindrical locksets and
mortises locksets without a deadbolt and can be installed in metal and wood door frames.
It includes an optional latch monitor and is field reversible for fail-safe or fail-secure operation.
The GK485 features 1/8" (3mm) horizontal strike adjustment to accommodate different installations.
