There's no easier way to covertly unlock the door from your desk than with this bundled kit.  Using equipment from SDC, a leading US based manufacturer of security, access control, and locking systems, this kit contains everything you need, less the wire, to setup your door buzzer system.  The concealed desk switch mounts easily to the underside of a desk for remote door control.  The switch not only includes a push button for momentarily energizing the electric strike, and unlocking it, it also comes with an on/off toggle switch for sustained bypass.  The toggle switch is helpful for keeping the door unlocked during deliveries, or situations where the visitor needs to make return trips to their vehicle, for example a sales rep making a presentation.  The person at the door will hear the click sound, indicating to come in.  A 24V DC transformer plugs into an outlet, and then connects via wire to the desk switch, and electric strike.  The strike provided is the Uni-Flex 45-A model. This is a universal electric strike with 3 different faceplates and mounting tabs to make installation simple, especially when jamb space is limited.  It comes with latch position status, and keeper status built in for door status monitoring when integrated into an access control system.  Managing your door traffic can now be done rather secretly with the push of a button.

Customer Questions & Answers

  1. Q Can this be used on a double door? answer now
    Asked by David on February 16, 2022 2:26 PM

    Yes this could be used in a double door setup. 

  2. A

    This can be accomplished if this system is being used with a Door Access Controller such as Linear E3 or Trilogy Panel. 

  3. A

    The Momentary open switch will disengage the lock for a few seconds. If the toggle switch is used, the lock will remain disengaged until the toggle switch is turned off and this switch will not automatically disable itself. 

  4. A

    Since this is a wired system you are only hindered by the maximum distance of the voltage based on the gauge of wire used to do the install. You would need to refer to our wire gauge page for distances.
