Dortronics 4800 Series intelligent door interlock controllers feature twelve field assignable inputs and seventeen configurable relay outputs for maximum flexibility. The new auxiliary relay lock output accessory adds to this flexibility with up to five factory-installable accessory terminal blocks. When form C contacts are required for additional functionality the auxiliary terminal boards can be specified on the purchase order and installed prior to shipment. These give the option of additional normally-open or normally-closed terminals with the 4800 Series controller.
Additional design features include a unique watchdog circuit that constantly monitors operation; LED indicators for input-output connection status; voltage spike and surge protection on all outputs; and adjustable propped door, panic release, and door unlock timers. Dortronics 4800 Series Smart Interlock Door Controllers are available as a board-only module or complete with a heavy duty 4-amp power supply.
