White Papers: Magnetic Locks, Chapter 3 of 4
ESSENTIAL DESIGN AND INSTALLATION ATTRIBUTES
August 15, 2007
Distributors, installers and end users have different priorities concerning magnetic lock design attributes. Presently, many magnetic locks on the market do not meet the requirements of all parties in the market chain. While recent installer surveys show they install one particular brand more often, many prefer to install a different brand. A lock the distributor prefers to sell or that is specified may be more difficult and time consuming to install, and these additional costs are passed on to the end user. Or, end users may not be particularly happy with a lock that looks like an extra large black brick hanging from the frame.
Surface Mount EMLock®
When choosing a lock, look for magnetic locks that have easy mount features and do not require special tools, special nuts, and mounting hardware that may increase installation labor and service costs. The SDC EMLock 1500 series includes interlocking and adjustable quick mount assemblies, captive mounting screws, and internal wire connection that enable fast and easy installation and troubleshooting (see Figure 6). Wires may be pulled before or after magnetic lock mounting. SDC also provides self-drilling and self-tapping mounting screws. These installation attributes can save up to 20 minutes installation time per lock compared to sealed magnets without wire access that require special mounting hardware and screws. This adds up to the savings of a full day’s labor when installing 25 locks.
Superior Appearance
The SDC Emlock design is ideal for end users concerned with aesthetics. All sides of the housing have either an anodized or plated finish without the usual unsightly black epoxy. Plus the elimination of black epoxy eliminates the potential for toxic fumes in a fire.
Lifetime Warranty
SDC magnetic locks are backed by the EMLock Lifetime Warranty.
Upgrade Capability without Removing the Lock from the Frame
While service requirements are rare for electromagnetic locks, it is inconvenient when a single internal part, including optional monitoring contact, timer or coil requires upgrade or service. If you have a replacement warranty, you must still contend with the inconvenience of ordering, shipping time, and installation of the replacement lock. While the lock itself is no charge, there is still the cost of labor to remove the old lock and install its replacement.
Even better than a lock replacement warranty, is a modular EmLock that is completely upgradeable and serviceable without being removed from the frame (see Figure 7). This provides a quick and economical solution to unserviceable locks. Use of interchangeable modules for field upgrades and service eliminate all issues associated with lock delivery, labor, and replacement costs.

 HiShear Magnetic Locks
Model 1561 2000 lbs
Model 1565 2700 lbs
SDC HiShear magnetic locks incorporate lateral adjustment of the shear stops (see figure 9), and an integrated door static sensors. One of the great things about adjustable shear stops is that they compensate for door misalignment. In addition, HiShear locks are equipped with a door static sensor to ensure that the door is at rest, and properly aligned before lock activation, also providing quieter operation. Without the relock delay provided by a door static sensor, sudden impact of lock engagement is not only noisier, but can cause what is known in the openings industry as ‘racking’ of the door, also described by door rattling and severe wobbling towards the bottom of the aluminum glass doors. Overtime, this door racking can cause continued alignment problems.
