I was invited to observe the installation of the Securitron GL1-based access control system onto a secured delivery dock sliding gate that was located in an industrial protected enclosure. The one-sided dock was equipped with an approximate ten-foot long by seven-foot-tall iron mesh faced sliding...

Three sides of the dock area are connected to buildings; a cement block building is on the fourth side. The front of this block wall building aligns with the sliding gate. The right side and the back of the block wall building are also attached to the dock. The rear of the door and the other side are additional buildings.
The dock is covered by tin roofing.
The Alarm Lock PDK3000 was installed onto the front wall of the block building approximately four feet from the opening side of the gate. The block wall building is at ground level and the dock is approximately three feet above ground level.
SARGENT POWER SOURCE
The power source is a surface-mounted 120VAC conduit attached to the block wall. Power was run from a duplex outlet to the SARGENT Power Supply. This enabled the power supply to be located out of sight at the rear of the block wall building. The SARGENT #3510 power supply was installed onto the block wall at approximately five feet above the concrete floor.
The #3510 power supply is UL Listed for Class II circuitry. This 24VDC power supply outputs 1.8Amps of filtered and regulated power. The enclosure is approximately one foot square. The power supply itself was used as a template to locate the three mounting holes. Wall anchors were used to secure the SARGENT #3510 onto the wall.
SECURITRON PUSHBUTTON EXIT
To unlock the gate from within the dock area, a Securitron PB2E Push Button was installed in a single gang box beneath the power supply. The PB2E is a two inch square, momentary, green lens Single Pole Double Throw (SPDT) Push Button.
Note: Although the dock area is covered, it is not protected from the elements. For this type of application, Securitron recommends using a Securitron PB Series Push Button that is designed for exterior as well as interior applications.
The pushbutton can be used to unlock the gate lock from within the dock, permitting egress and access. It was wired into the timer function in the Alarm Lock PDK3000. This way when the push button is pressed, the gate lock will be powered and unlock for a time-adjustable period.
The time required for the installation was approximately three hours, which included bringing in a welder and electrician to provide 120VAC for the SARGENT power supply. The gate lock mounting bracket was supplied by the welder and manufactured prior to the installation. See the wiring diagram for installation details.
The gate lock/remote access controller system provides access control for this single-gate dock area by using known hardware and making use of existing proximity card equipped identification badges. By taking advantage of an existing identification technology and having a number of installed Alarm Lock access control products, this facility saved money by using existing proximity cards, and saved time since the learning curve for the DPK3000 is minimal.
