• How do I change the fail-safe/fail-secure setting on my GEM electric strike?

  Fail-safe or fail-secure is field reversible by reversing the round screw. For example, on the GK450/480 series, it is fail-secure when '2' is facing up, and fail-safe when '1' is facing up.

• How do I pair my GEM Ellis Bluetooth Headphones?

  Turn the headphones on. The LED will flash to indicate it is in pairing mode. Select 'GEMLINE HP' on your device's Bluetooth list. If asked for a PIN, enter '0000'.

• What is the warranty period for GEM access control products?

  Most GEM access control products, like the GK800 series strikes, are warranted against defects in material and workmanship for a period of 3 years from the date of sale.
