HES 4591-01-00-628 Exit Paddle Switch
The HES 4591-01-00-628 is a purpose-built exit paddle actuator engineered for access control systems managing emergency egress and controlled exit points in commercial and institutional facilities. This device balances accessibility compliance with security integrity—a critical design requirement in facilities where both rapid emergency evacuation and controlled entry must coexist.
Key Features
- ADA-Compliant Paddle Actuator: Paddle mechanism meets ADA accessibility standards, ensuring that occupants with varying physical abilities can operate the switch reliably during emergency egress. No ambiguity in operation—a light push activates the mechanism, eliminating confusion in high-stress situations.
- Commercial-Grade Durable Construction: Built for high-traffic environments where the switch may be actuated hundreds of times per day (fire drills, routine operations, emergency events). Mechanical reliability reduces maintenance callbacks and unplanned downtime at security-critical exit points.
- Seamless HES Integration: Connects directly to HES access control infrastructure, eliminating protocol translation or third-party gateway requirements. Native integration simplifies wiring, commissioning, and future troubleshooting—your integrator doesn't need to solve compatibility problems during installation.
- Industry-Standard Mounting Specifications: Follows established physical mounting patterns for exit hardware, allowing flexible installation at frame-level or surface positions depending on facility layout and code requirements. Standardized mounting reduces custom engineering and speeds deployment across multiple facilities.
- Emergency Exit and Controlled Access Scenarios: The 4591-01-00-628 works in dual-use applications: emergency evacuation (where rapid pushbutton egress is mandated by fire code) and controlled access points (where log-and-deny entry control is required). This flexibility is essential in secure facilities, healthcare campuses, and corporate multi-tenant buildings where not all exits behave identically.
Integration & Compatibility
The 4591-01-00-628 (often searched as 4591 01 00 628) integrates with HES access control systems as a field input device. It provides a clean contact closure signal when the paddle is pressed, allowing the access control panel to log the event, trigger alarms if unauthorized use is detected, or unlock paired exit hardware on valid egress attempts. Typical deployments pair this switch with electric strike locks and exit hardware to create a complete egress management solution.
For facilities standardizing on HES infrastructure, this switch eliminates the need for adapter modules or multi-protocol gateways. Direct wiring to the access control panel reduces points of failure and simplifies annual compliance audits.
Deployment Considerations
This is a field-mounted electromechanical device—no firmware updates, no IP address, no network connectivity required. It works in offline-capable access control systems and in networked enterprise deployments alike. Install height, door frame compatibility, and local fire code requirements (which vary by jurisdiction) should be confirmed before ordering. The paddle actuator itself is stateless; the intelligence lives in the access control panel that receives its signal.
Frequently Asked Questions
Q: Is the HES 4591-01-00-628 suitable for exterior emergency exits?
A: The paddle mechanism is designed for standard commercial environments. If you need an exit switch exposed to rain or temperature extremes, consult your access control integrator about weatherproofing enclosures or alternative hardware rated for those conditions.
Q: Does this switch work with non-HES access control panels?
A: The 4591-01-00-628 is engineered for HES systems. Compatibility with third-party panels depends on whether those panels can accept dry contact closure inputs at the voltage and current specifications this switch provides. Check with your integrator and the third-party panel manufacturer before cross-system deployment.
Q: What is the expected service life of the paddle mechanism?
A: Commercial-grade construction is designed for high-cycle environments. Actual longevity depends on usage frequency and maintenance practices. Refer to HES maintenance documentation for lubrication and wear intervals.
Q: Can the 4591-01-00-628 be installed on both interior and exterior doors?
A: It is suitable for interior and protected environments. Exterior installations require weatherproof enclosures or door-frame-integrated housings. Verify compatibility with your specific door frame and local egress code before installation.
Q: Is any power supply required for the paddle switch?
A: The paddle mechanism is passive—it generates a contact closure signal when pressed. Power is not drawn by the switch itself; power for associated access control hardware (locks, readers, panels) is supplied separately via the access control system infrastructure.
Q: How does the HES 4591-01-00-628 comply with emergency egress codes?
A: The ADA-compliant paddle design and contact closure operation meet accessibility and egress standards in most U.S. jurisdictions. However, fire codes and egress requirements vary by building type and state. Your facility's architect or code compliance officer should verify that this switch meets your specific local and life-safety requirements before deployment.

The HES 4591-01-00-628 is a straightforward, low-complexity exit paddle actuator—and that's exactly what you want in an emergency egress device. No electronics to fail, no firmware to patch, no IP address to manage. A properly installed 4591-01-00-628 will sit on a door frame for years and do its job: convert a button press into a contact closure that your access control panel understands.
Technical Highlights:
- ADA Paddle Compliance: The actuator meets accessibility standards for force and activation clarity. In a real evacuation, an 8-year-old, an elderly resident, or someone with limited hand strength can operate it without ambiguity. That matters when life-safety is on the line.
- Native HES Integration: Direct wiring to HES panels eliminates protocol gateways and simplifies field troubleshooting. If the switch ever fails to signal a panel event, your technician knows the problem is the switch, the wiring, or the panel—not a missed API call or a third-party translator.
- Commercial-Grade Mechanical Durability: Built for high-cycle use (hundreds of actuations per day in busy facilities). Standardized mounting ensures it can be swapped out without custom engineering if the mechanism wears out after years of service.
Deployment Considerations:
- This is a passive contact device. It doesn't authenticate or make security decisions—your access control panel does. The 4591-01-00-628 is only as secure as the system that receives its signal. Ensure your panel is configured to log and audit exit events and to deny unauthorized egress attempts.
- Fire codes vary significantly by jurisdiction and building type. A paddle switch that works in a corporate office may not satisfy requirements for a hospital, prison, or high-hazard industrial facility. Verify code compliance with your architect or code official before final installation.
- Exterior or high-moisture installations require weatherproof enclosures. Bare paddle switches in rain will corrode. Plan for appropriate housings if the exit point is outdoors or in a humid environment.
Position the 4591-01-00-628 at healthcare facilities, corporate campuses, and multi-tenant commercial buildings where you need both controlled access and rapid, ADA-compliant emergency egress. This is the right choice when your integrator specifies HES infrastructure and your code requires a hands-free or easy-to-actuate exit mechanism.
