We’ve discussed the value low energy operators provide for the privacy needs of restrooms. But, their true value extends to high-traffic areas in schools, hospitals, and commercial buildings. With increasingly codified ADA compliance requirements and the demands of access control, management, and privacy, automated door operation use has expanded as well.
Understanding Low Energy Operators
Low energy operators are designed to open and close doors at a slower speed and with less force than high energy automatic operators, making them suitable for environments where a "knowing act" is required to initiate door movement. Unlike high energy operators, which rely on sensors to open automatically, low energy operators require a conscious action, such as pushing a button or activating an actuator, which aligns with safety and accessibility needs in spaces where unintentional door openings could pose risks.
As we discussed in our previous DHI article, low energy operators are increasingly required not only for exterior doors but also for interior applications, particularly as ADA compliance and access control requirements continue to evolve. Integrating a low energy operator involves several essential components:
The Sequencer: A sequencer manages the timing of operations in a door system, ensuring the latch releases before the door opens, preventing door or operator damage. Not all operators include built-in sequencing; if missing, an external module is essential for system harmony.
Onboard Power: Low-energy operators may need an external power supply to support connected devices if onboard power isn’t enough. Power output should be between 900mA-1A for optimal functionality.
The Actuator: Actuators send signals to start the door sequence when triggered by a button, sensor, or access control device. Incorrect wiring can lead to integration issues, especially with access control systems. Touch-less actuators offer convenience but can be overly sensitive, while mechanical actuators are more reliable in high-traffic areas. LED-equipped actuators provide visual cues, preventing users from pressing multiple times out of confusion.
The Latch: Access control integration with low-energy operators can involve either electric strikes or motorized latch retraction (MLR).
- Electric Strikes: Unlock by releasing the latch when access is granted, enabling hands-free entry. They are generally cost-effective and easy to install but can be noisy and sometimes require frame modifications. Electric strikes are available as fail-safe (unlocks during power failure) or fail-secure (stays locked during power failure). They work well on 12 or 24 volts but may struggle with door preload issues, potentially damaging the operator if not properly addressed.
- Motorized Latch Retraction (MLR): MLR systems pull the latch flush with the door edge, allowing quieter, resistance-free door swings. They don’t require frame alterations and align better than strikes over time, preserving security and door appearance. MLR systems are often preferred for ADA compliance as they reduce the physical effort needed to open doors, making them suitable for sensitive environments.
Beyond Bathrooms: Expanding Applications
Low-energy operators serve a wide array of applications, offering solutions that go far beyond restroom privacy. Now that we’ve covered their components, let’s review where they can be used.
Healthcare Facilities
In hospitals and clinics, hands-free, ADA-compliant access is essential not only for patient care but also to improve workflow and hygiene. Low-energy operators facilitate easy entry for patients, medical staff, and visitors, especially those using wheelchairs or other mobility aids. When paired with motorized latch retraction (MLR) systems, these operators create access points that minimize physical effort and reduce contact with door surfaces, promoting better hygiene—a crucial factor in healthcare settings. In high-traffic areas like emergency rooms, ICUs, and surgery entrances, these systems allow smooth transitions while supporting the quick movement of medical teams and equipment.
Educational Institutions
With ADA requirements in place, these operators ensure that students, staff, and visitors can navigate doors without obstacles, fostering an inclusive environment. They also support security protocols in specific areas, allowing facilities to control access to spaces such as laboratories, libraries, and administrative offices, which may need restricted entry at certain times. When integrated with access control systems, low-energy operators add an extra layer of safety, giving educational institutions the flexibility to secure areas when necessary while still ensuring easy access during emergencies.
Public Spaces and High-Traffic Venues
Airports, government buildings, and other high-traffic public spaces demand efficient, accessible door systems to manage the flow of large numbers of people. In such environments, low-energy operators improve accessibility and reduce congestion around entryways, enhancing overall crowd control and safety. In airports, for example, operators enable smooth access to restrooms, terminals, and secure areas, helping travelers with reduced mobility to move easier.
