Access Control System Considerations, continued from p8
Automated gates are obviously a key factor in access control. Pfeiffer says the main types of automatic gates used for commercial and residential settings are slide gates, swing gates, and barrier arms, each with its own unique features.
SWING GATES Swing gates are the most common gate style in either single or dual configuration. The main concern in either case is that the driveway entrance must be wide enough for access by a fire truck. By most building codes, the minimum opening is 14 feet. That goes for the slide gate too.
SLIDE GATES Where the location doesn’t allow for a swing gate, slide gates are used. Slide gates have several mounting options. A track can be installed for the gate to roll on, a cantilever system can be used if the land surrounding the entry isn’t level, or an overhead track system can be installed.
BARRIER ARM A barrier arm is used when quicker access is desired and pedestrian traffic does not need to be controlled. A barrier arm can also be installed in conjunction with a swing or a slide gate. This configuration is often promoted to prevent tailgating into a property, but barrier arms also protect the gates themselves. A gate operator is a device designed to automatically and remotely open and close a wide variety of gate types. Pfeiffer says many operators are now able to add solar power and battery backup capabilities, and some offer cellular capabilities for diagnostic control. Most gate operators function by either using a key fob style remote control, or a card system that goes to an access panel.

D&D Technologies Announces New Latch D&D Technologies, the leader in high-performance gate hardware, introduces the LokkLatch® Deluxe Series 3 to its versatile line of LokkLatch gate latches. The new LokkLatch Deluxe Series 3 is the premium privacy and security gate latch with simplified through-post installation, operates, locks and unlocks from both sides of the gate and is easy to install. Designed for commercial or residential applications, it is a complement to D&D’s popular LokkLatch® line that includes the general purpose LokkLatch and the LokkLatch 3 Plus residential security gate latch. “We are excited to introduce such an improved and innovative gate latch that features several advantages to make installation quick and easy,” says Jim Paterson, D&D’s senior vice president of sales and marketing. “The improved strength of the new latch makes it perfect for the higher security and privacy applications.” With a new contemporary body design, the LokkLatch Deluxe Series 3 has a reinforced body and side fixing legs that are notably stronger and tougher than previous designs. The mounting bracket that secures the latch to the fence post also serves as the “fitting jig” (template) to provide significantly faster and easier installation. The innovative fitting jig naturally aligns the drill-hole on both sides of the post so that the hole is level at all times. Installation requires only one drilled hole. The snap-fit connector rod joins the two latch housings with a press-fit connection in the push-button to prevent rods from falling out during installation or dropping down the center of hollow posts, simplifying installation. The LokkLatch Deluxe Series 3 is available in black or white, keyed alike or keyed-different versions and is backed by a limited lifetime warranty. It can also be vertically and horizontally adjusted to ensure proper fit and 12
