HES 74R1-130 Electric Strike for Rim Exit Devices
Overview
The HES 74R1-130 is a purpose-built electric strike engineered for retrofit and new-construction deployments where panic hardware compliance and centralized access control must coexist. This device integrates directly with rim exit devices equipped with 3/4" (19.1 mm) Pullman latchbolts — a standard specification in commercial panic hardware — allowing building operators to unlock doors electronically without removing or replacing existing panic bars. The 74R1-130 bridges traditional mechanical egress hardware and modern access control infrastructure, making it a practical choice for facilities managing both emergency exit requirements and security protocols.
Key Features
- Compatible with 3/4" Pullman Latchbolt Rim Exit Devices: The strike is designed for a specific latchbolt dimension that is common across commercial panic hardware brands. This compatibility eliminates the need to replace panic bars during retrofit, reducing installation labor and downtime.
- Dual Voltage Operation (12/24 VDC): Accepts both 12 and 24 volt DC power sources, accommodating different building power architectures without requiring separate variants. This flexibility simplifies inventory and integration with mixed access control systems.
- Aluminum Frame Mounting: The strike mounts directly to aluminum-framed doors, the standard material for commercial office and institutional glass-door systems. Mounting is straightforward where the door frame is aluminum; verify frame material on site before ordering.
- Integration with Existing Access Control Systems: The 74R1-130 connects to standard access control panels, card readers, and credential platforms already in place. No proprietary middleware or vendor-specific controllers are required — it functions as a basic solenoid strike on a standard access control output.
- Suitable for Retrofit and New-Construction Applications: Whether converting a manual panic exit to electronic control or installing access control from the ground up, the 74R1-130 performs in both scenarios. In retrofit work, the ability to retain existing panic hardware reduces project scope and cost.
- Compliance with Emergency Egress Standards: When properly wired to access control systems with manual override and emergency power backup, the strike maintains code-compliant emergency exit function. However, the installer must ensure the overall system meets local fire codes — the strike alone does not guarantee compliance.
Integration and Deployment Considerations
The 74R1-130 is a passive electromechanical component — it contains no microcontroller, analytics, or network interface. Integration responsibility falls entirely on the access control system. Ensure your access control panel has a dedicated solenoid output circuit with appropriate current capacity (typically 500 mA to 1 A at the selected voltage). Most commercial access control platforms support rim strikes natively, but verify driver compatibility with your specific panel before final ordering.
Power routing is a critical field consideration. The strike draws current continuously during the unlock dwell period — typically 0.5 to 2 seconds. In battery backup or emergency scenarios, confirm that your backup power supply has sufficient capacity to hold the strike in the unlocked state for the required duration. Undersized backup power is a common commissioning failure in retrofit projects.
Aluminum frame compatibility assumes a standard commercial door frame profile. Verify the frame material and profile on site; if frames are steel or hollow-metal, different strike models may be required.
When to Choose a Different Model
If your rim exit devices are equipped with 5/8" latchbolts (a minority in modern commercial hardware), the 74R1-130 will not fit — consult the HES product family for the correct strike dimension. If your doors are non-aluminum framed (steel, hollow-metal, wood), different HES strike models support those materials. For facilities requiring fail-safe operation (strike remains unlocked on power loss for emergency egress), ensure your access control system is configured for that function; the strike itself is fail-secure (locked on power loss), which is the default for most commercial deployments.
Frequently Asked Questions
Q: What voltage should I order, 12 or 24 VDC?
A: The 74R1-130 operates at both 12 and 24 VDC — you do not choose one or the other. Wire it to whichever voltage your access control panel provides. If your panel outputs 24 VDC, connect the strike to that circuit. Most commercial panels use 24 VDC, but verify your panel's specifications before installation.
Q: Can the 74R1-130 work with wireless or cloud-based access control systems?
A: Yes, as long as your wireless or cloud access control system has a local access control panel or gateway with a hardwired solenoid output. The strike itself is not networked — it only requires DC power and a relay signal from the access control circuit. The integration point is at the panel, not at the strike.
Q: Does the 74R1-130 include a manual override in case of power loss?
A: The strike itself does not include a mechanical override. Manual override during power loss is provided by the panic bar — users can push the bar open mechanically at any time. The strike prevents electronic unlock unless power and a valid access signal are both present.
Q: Is the 74R1-130 NDAA-compliant or restricted from federal purchase?
A: No information in the evidence indicates NDAA restrictions on this model. However, confirm with your compliance officer or procurement team if this is a requirement for your facility, as access control components may fall under supply-chain review policies in federal or critical-infrastructure projects.
Q: What happens if the access control system fails — can people still exit?
A: Yes. The panic bar remains mechanically functional at all times. System failure does not prevent egress. However, if you require fail-safe unlock (automatic unlock on power loss), that function must be wired into the access control panel logic, not the strike.
Q: Does the 74R1-130 require maintenance or periodic testing?
A: Like all solenoid strikes, periodic functional testing (manual unlock cycles) is recommended as part of regular access control maintenance. No lubrication or internal service is required. Test the mechanical panic bar function and electrical unlock function quarterly to ensure code compliance.

The HES 74R1-130 is a straightforward electromechanical component that solves a real problem: retrofitting access control onto existing panic hardware without ripping out panic bars. The dual voltage 12/24 VDC operation means you're not limited by power architecture, and the 3/4" Pullman latchbolt compatibility covers a large swath of commercial panic hardware. What matters in the field is that the 74R1-130 integrates into standard access control circuits — no fancy protocol, no network requirements, just a solenoid on a relay output.
Technical Highlights:
- Dual Voltage (12/24 VDC): Eliminates the need to stock two SKUs or redesign power architecture to fit a single voltage spec. Wire it to whatever your panel outputs; the strike works at both levels, reducing installation friction in mixed-voltage facilities.
- 3/4" Pullman Latchbolt Compatibility: This dimension is industry-standard in commercial rim panic hardware. Confirm your existing hardware matches before ordering, but if it does, you avoid the cost and downtime of replacing panic bars during retrofit.
- Aluminum Frame Mounting: The strike mounts directly to standard aluminum door frames common in commercial glass-door systems. Field verification of frame material is non-negotiable; if you're on steel or hollow-metal frames, a different strike is required.
Deployment Considerations:
- Power Budget Verification: Solenoid strikes draw meaningful current during the unlock dwell period. If your access control panel's output circuit or backup power supply is undersized, the strike may not pull fully or hold long enough. Verify solenoid current draw against your panel's circuit spec sheet — a common retrofit failure point.
- Code Compliance Wiring: The strike itself is fail-secure (locked on power loss), which is correct for most commercial security deployments. However, if your facility requires fail-safe operation (automatic unlock on emergency power loss), that logic lives in the access control panel configuration, not in the strike. Confirm this with your AHJ or life-safety engineer before final commissioning.
- No Mechanical Manual Override: The strike does not include a keyway or mechanical release. Egress is always possible via the panic bar itself — the strike only prevents electronic unlock without power and signal. This is a security feature, not a limitation, but it matters if you're designing for "unlock on evacuation" scenarios.
The 74R1-130 is the right choice when you're retrofitting panic hardware into an access control system and the frame is aluminum and the latchbolt is 3/4". It is not a smart device — it does not require network setup, firmware updates, or integration middleware. For warehouse, commercial office, or institutional facilities converting manual exits to electronic control without a complete door hardware overhaul, the 74R1-130 is a cost-effective, low-complexity solution.
