Doorking 1835 PC Programmable

Doorking 1835 PC Programmable

The Model 1835 is an ideal telephone entry system suited for apartment and gated community applications as well as office buildings and industrial sites that have a separate access control system, or require telephone entry only. The single-line LCD display features big 1/2-inch characters for easy viewing and your personalized message scrolls across the screen from right to left when the system is not in use. Our unique “One Touch” CALL button makes this system one of the easiest to use on the market today! The built-in electronic directory, easy to use Remote Account Manager programming software, card reader interface and expandability options make this unit an ideal choice for those applications with a large number of system users and entry locations. Up to 16 card readers can be interfaced with the 1835 to provide access control. Additionally, our elevator control module restricts which floors a guest or system users have access to, making it an ideal system for high rise buildings. For additional security, the 1835 allows you to monitor activity AS IT HAPPENS on your computer display (requires RS-232 connection), and with our anti-pass back memory, you can enable a TRUE anti-pass back system in one of three different configurations; passive, active and trap.

Traffic control spikes

  • Stand-alone Traffic Control Spike Systems
  • Surface mount spikes install easily without trenching and double as a speed bump
  • Spring loaded surface mount available in 3 foot sections
  • Flush Mount below ground assembly available with weighted or spring loaded spikes

Traffic control spikes are ideal for controlling traffic direction and speed through a controlled entry location. Traffic spikes prevent vehicles from proceeding through a traffic lane in the wrong direction by enforcing one-way traffic lanes. Flush mount spikes are available with Spring Retraction or with Weighted Retraction. Speed bumps force drivers to slow down while driving through the controlled entry point. They are also ideal for keeping vehicular traffic at a safe speed while driving over traffic spikes.
