HES RP-44MOMENTARY Momentary Access Control Switch
The RP-44MOMENTARY combines the proven RP-44 power supply platform with an FA-200 momentary push-to-exit switch, delivering a compact auxiliary control solution for access control installations. This device generates brief contact closure signals to trigger door release mechanisms, reader authentication events, and egress workflows in secured facilities. If you're integrating card readers, keypads, or biometric systems into a multi-door access control architecture, momentary switching is the standard signal type most locking hardware expects — this unit handles that reliably without custom signaling logic.
Key Features
- Momentary Contact Closure: Delivers a brief electrical pulse when activated, the standard signal type for triggering electromagnetic locks, mag locks, and solenoid-based door release mechanisms. Most access control integrations expect momentary logic — this eliminates the need for custom relay conditioning.
- 12/24 VDC Auxiliary Switching: Operates across dual voltage rails common in facility power systems, so you can integrate into existing infrastructure without adding separate power conditioning. Flexible voltage support reduces installation complexity across mixed-voltage deployments.
- Card Reader & Biometric Compatibility: Works with standard access control output protocols — integrates card readers, PIN pads, biometric scanners, and multi-factor authentication workflows without custom interface logic.
- Standard & Delayed-Egress Support: Handles both immediate push-to-exit scenarios and delayed-egress security applications where compliance or safety codes require a timed release interval.
- Compact Form Factor: Space-efficient design fits tight electrical closets, equipment racks, and wall-mounted installations where cabinet real estate is limited.
- RP-44 Platform Reliability: Built on the established RP-44 power supply architecture, a proven design in thousands of access control deployments. Reduces field failure risk and supports long-term parts availability.
Integration & Compatibility
The RP-44MOMENTARY (often searched as RP 44MOMENTARY) integrates into standard access control system architectures that rely on momentary contact closure to drive relay logic and electromechanical actuators. Compatible with card reader systems, proximity keypads, multi-reader authentication controllers, and emergency egress requirements. Designed for indoor installations where access control precision directly impacts facility security and operational continuity — deploy in server rooms, data centers, secured entry points, and commercial buildings. The 12/24 VDC dual-voltage design enables flexible integration into diverse facility power infrastructures without custom conditioning.
When to Choose a Different Model
If your access control system requires a latching (maintained) contact instead of momentary closure — for example, to hold a lock in the open position for extended periods — you'll need an alternative configuration. Consult your access control panel documentation to confirm whether momentary or maintained signaling is required; the two are not interchangeable. Similarly, if you need wireless or networked egress capabilities (WiFi-enabled or IP-based exit triggers), this hardwired momentary switch is not the right fit.
Frequently Asked Questions
Q: What's the difference between momentary and maintained contact closure?
A: Momentary contact closes only while the button is pressed and opens immediately upon release — standard for triggering solenoid locks and electromagnetic strikes. Maintained contact stays closed after activation until manually reset. Most access control systems expect momentary signaling; verify your panel specs before ordering.
Q: Can the RP-44MOMENTARY work with both 12V and 24V systems?
A: Yes. The unit supports 12/24 VDC operation, so it integrates into facilities with mixed voltage infrastructure without requiring separate power supplies for each voltage rail.
Q: Is the RP-44MOMENTARY suitable for delayed-egress door release?
A: Yes. The momentary switch design is compatible with delayed-egress security applications. Verify that your access control panel and door hardware support the timed release interval your security code requires.
Q: What locking hardware does the RP-44MOMENTARY trigger?
A: Momentary contact closure activates electromagnetic locks (mag locks), solenoid-based electric strikes, and push-to-exit mechanisms controlled by your access control panel. Confirm that your specific lock hardware expects momentary signaling, not maintained closure.
Q: Does the RP-44MOMENTARY integrate with biometric or multi-factor authentication readers?
A: Yes. It works with card readers, keypads, biometric scanners, and multi-reader access control architectures. The momentary switch provides the output signal that your authentication system triggers once a credential is verified.
Q: What's the warranty on the RP-44MOMENTARY?
A: Check the product documentation or contact the manufacturer for specific warranty terms. Standard industrial control devices typically carry a 1–2 year manufacturer's warranty; OEM terms vary.

The RP-44MOMENTARY is a no-nonsense auxiliary control device built for access control integrations where momentary contact closure is the expected signal type. If your access control panel or door controller is waiting for a brief pulse to trigger lock release, this unit delivers exactly that — nothing more, nothing less. The 12/24 VDC dual-voltage design is a real advantage in facilities with mixed power infrastructure; you don't need separate switches for different voltage zones.
Technical Highlights:
- Momentary Contact Closure Logic: Outputs a brief electrical pulse on button press, the standard activation signal for solenoid locks, electromagnetic strikes, and relay-based access control workflows. Eliminates the need for custom signal conditioning in most installations.
- 12/24 VDC Dual Voltage Support: Works across both voltage rails common in facility power systems. Reduces the number of separate power supplies needed and simplifies integration into mixed-voltage deployments.
- RP-44 Power Supply Platform: Built on a proven architecture deployed in thousands of access control systems. Offers long-term parts availability and reduces the risk of field failures associated with newer, less-tested designs.
Deployment Considerations:
- Verify your access control panel's output specification before ordering — some systems expect maintained contact instead of momentary closure. The two are not interchangeable, and a mismatch will cause the locking mechanism to fail.
- Confirm that your door hardware (mag lock, electric strike, or solenoid) is rated for the voltage and contact duration the RP-44MOMENTARY provides. Undersized hardware may chatter or fail prematurely.
- If you need wireless exit capability, IP-based remote triggering, or networked egress control, this hardwired momentary switch is not the right tool — consider a networked access control receiver instead.
The RP-44MOMENTARY is a solid fit for data centers, server rooms, and multi-door commercial access control systems where reliable, simple momentary switching is non-negotiable. Its dual-voltage design makes it particularly useful in larger facilities with legacy and modern power infrastructure running side-by-side.
