Whether you’re installing or selling smart locks, you’ve probably encountered industry-specific terms like “Single-Action,” “Dual-Action,” and “Double-Speed.” If these terms seem confusing, this guide will help clarify them, making it easier to understand the smart lock features that best meet your needs.

What is “Single-Action”?

“Single-Action” refers to a smart lock configuration where only the inner door handle is functional, allowing it to open the door when pushed down. However, the handle outside remains fixed and non-operational. This setup provides an added layer of security since only those inside can operate the door handle. For example, if used in a residential setting, only individuals inside the home can open the door without a key or passcode, offering enhanced control over entry.

Understanding “Dual-Action”

In a “Dual-Action” lock, both the interior and exterior door handles can be pushed down to open the door. This design is practical for frequently accessed doors, like office or shared residential entries, where users often need easy access from either side. For instance, in a shared office environment, a dual-action lock allows staff members to freely move in and out without needing special permissions, making it a convenient and efficient choice.

Exploring “Double-Speed”

“Double-Speed” represents a feature that enables quick-locking and unlocking from either side. The exterior handle can be lifted to quickly lock the door, while the interior handle can do the same for locking or unlocking with a swift push-down movement. This feature requires a “double-speed lock body,” a specific type of lock mechanism designed for rapid access and secure closure. Commonly used in settings requiring frequent, fast access—such as emergency exits or high-traffic areas—a double-speed lock ensures smooth, quick operation, enhancing security and efficiency. For instance, in a healthcare facility, a double-speed lock on a main entry door could save valuable time during emergencies by allowing instant access with one simple motion.

Mechanical Locks in Smart Lock Systems

In the smart lock industry, “mechanical” typically refers to traditional mechanical locks, which vary depending on their handle and lock body configurations. Standard mechanical locks often pair with single-action or dual-action handles, providing basic entry functionality. There are also dual-speed mechanical locks, compatible with double-speed handles, for locations that benefit from faster entry and exit. For example, a single-action mechanical lock might be chosen for personal rooms or low-traffic spaces where privacy is prioritized, while double-speed models fit high-traffic areas needing frequent, secure access.

Additional Insights: Fingerprint and Mechanical Locks

Generally, most fingerprint locks are designed with a dual-action, double-speed lock body, enhancing convenience for users by allowing swift entry and exit. In contrast, many standard mechanical locks are built with single-action lock bodies, offering simpler functionality focused on basic security. Knowing the difference can help buyers select a lock best suited to their space’s traffic and security needs.

By understanding these features, buyers and sellers alike can make informed decisions about smart lock types and functionality, choosing options that match specific security and convenience preferences.
