DoorKing instructs that the pedestals for mounting the operators be level and placed 4 inches above grade. Besides for appearance, keeping things level minimizes bearing wear, enhances balance and will hopefully keep water out of the machine.
Our project controlled an entry lane and an exit lane of traffic. The entry and egress gates would be controlled by either a card reader or an activating button in the office. After the initial prepping was performed, the owners decided they wanted to also operate the gates via a keypad for entry and egress, but there would only be a limited number of individuals issued a P.I.N. to raise the gates.
It was also decided that at certain times it would be desirable to raise the gates and keep them raised.
We provided nifty keypads and toggle switches.
The DoorKing #1601 is a standalone product which has a good selection of accessories and features.
It is available with several choices of gate arm. The least expensive and most often used are the wood arms.
For our area of the country, venting and heating for the operator housing was recommended. These modules wire right into the operator’s line voltage supply and are thermostatically controlled.
Our installation required minimal wiring. We needed a line voltage feed from the building to each gate operator. This circuit would normally remain energized. By assigning and marking the circuit breaker, it would be possible to cut power if maintenance were required.
We needed to send an open activation signal to the gate operator. This is a low voltage momentary closure. The DK has in internal timer which you set in the pedestal. It is a rotary control which can be set for open times up to 59 seconds.
We needed to wire in the safety sensor. We did not want a gate to lower onto a vehicle, so a photo beam was mounted on each operator directly under the gate arm. As long as the beam was blocked, the barrier arm would not lower.
We were sending the following four open commands to each unit:
- Card Reader - A valid credential would close a switch which actuated the gate to open.
- Wall-Mounted Button - We installed a momentary button on the wall. They could open the gate momentarily if someone did not have a credential.
- Toggle Switch - the toggle (on/off) switch could be used to open each gate and keep it open for as long as was required. The gate would lower after the switch was turned off.
- Keypads - As previously mentioned, the owners decided they wanted keypads to also be able to open the gates. This was after the cabling had been pulled and the pedestals had been fabricated. We added keypads and programmed them as requested.
The 1601 operator is designed for single-lane (14-foot maximum) vehicular traffic control in high traffic commercial and industrial applications. The 1601 operator is designed so that it can be mounted on either the left or right hand side of the roadway.
Electronic limit settings control the full open and full closed position of the barrier gate. Magnetic sensors do not involve micro switches with levers and trippers, and thus there is no contact between the sensor switch and the movable gate mechanism; resulting in a more reliable design. These sensors can be readily readjusted by the installer if necessary.
Since DK #1601 operators are designed so that they can be mounted on either the left or right hand side of the roadway, if it is necessary, the installer can mount the barrier arm through the other side of the housing without exotic tools or specialized skills required.
The DK 1601 is available with a 14-foot aluminum or wood arm, or 12-foot plastic arm. A folding arm kit can be added for low headroom applications
The DK 1601 360-degree gear box rotation provides for smooth operation and even wear, increasing the life span of the operator. The gears remain immersed in oil. The gate goes from fully closed to fully open in about 1.5 seconds, and travels from fully open to fully closed in 1.5 seconds. The hold open time is a separate setting, and is controlled by other factors as already described. My customer liked the snappy performance.
To simplify installation and wiring, if loop detectors are required, they are modular and plug into the controller.
Make sure the site is prepped and the gate itself is operating well, then carefully select the right equipment. In this case the DoorKing 9100 and BEA remote filled the bill.
Securitron has several gate locking solutions which can be used to design the locking solution for your next gate security application.
