A variety of door buzzer kits for ingress/egress control for shops, stores, warehouses, hangars, offices, coolers, food service outfits, etc.
When you can visually screen your arriving visitors or customers, i.e. directly thru a glass door/window or from closed circuit video camera, use the D-Striker door buzzer system to grant access at the push of a button. Use the UniPort system instead if you have a glass door or any door where an electric deadbolt or electrogmagnet would work better as the locking device. A D-Striker control module works jointly with a Doorstrike device at the jamb of the door and additionally carries a pushbutton for the attendant. Whereas the UniPort control module works jointly with either an electric deadbolt or an electromagnet.
At the push of the release button on the handy module, an open signal is sent to the Doorstrike for a preset time window, by the buzz-in system. No need to keep the button pressed until the guest is in. Automatic open signal time window is adjustable from 1 to 60 seconds. You can also temporarily keep the door unlocked while closed for free access as desired.
