Product Overview

Overview

The HES 7501 Series Electric Strike is a Grade 1 heavy-duty electric strike for 3-hour fire-rated door openings that incorporate door pressure/preload. It is designed to work regardless of the amount of pressure imposed on the door as it interacts with a standard cylindrical lockset (with up to 3/4" latchbolt throw), still locking, even if the door is warped, misaligned, or has heavy weatherstripping that may cause a normal strike to bind. The 7501 strike is made with stainless steel, has an innovative preload release (patented), and reliably provides secure controlled access to high traffic commercial settings and is a fire door safety code compliant electric strike. Thus, it makes sense when considering the HES 7501 series electric strike for any office building, hospital or school, or any facility with a need for fire-door performance integrity, and where reliable access under pressure is key.


Preload-Capable Fire Door Solution

"Preload" refers to pressure on a door that pushes the latch against the strike, often caused by HVAC air pressure, tight seals, or door misalignment. Under these conditions many strikes jam and fail to unlock, but the HES 7501 is engineered to operate smoothly under up to 15 lbs of preload. Its preload release function ensures the latchbolt releases even if there's binding pressure, preventing costly door malfunctions or safety hazards in an emergency. This strike is specifically UL 10C listed for 3-hour fire-rated doors (fail-secure mode), so it will remain locked during a fire but still allow egress when released, meeting life safety codes. By combining fire-rating with preload capability, the 7501 series solves a critical problem in fire-door applications where weather stripping or warped frames could otherwise compromise the lock's function.


Heavy-Duty Security and Durability

Built to withstand rigorous commercial use, the 7501 strike features all-stainless steel construction and a reinforced design. It is tested to hold up to 1,500 lbs of static force and 70 ft-lbs of dynamic impact, resisting heavy kicks and blows. The mechanism endures 1,000,000+ lock/unlock cycles for long-term reliability in high-traffic entrances. The unit is fully tamper-resistant, deterring attempts to pry or manipulate it. It also carries multiple compliance certifications – including ANSI/BHMA A156.31 Grade 1 and UL1034 burglary-resistant listing – verifying its robust security performance. Backed by the ASSA ABLOY SecuriCare 5-year no-fault warranty (extendable to 10 years when used with an optional SMART Pac III power controller), the HES 7501 gives installers and facility managers peace of mind that this hardware will perform under stress without fail. In short, this strike's durable build and high strength ratings make it suitable for protecting critical door openings in banks, data centers, and other secure facilities.


Easy Installation & Versatility

The HES 7501 is designed for quick, flexible installation in the field. It operates on dual voltages (12 or 24 VDC) with a low current draw, accommodating common power supplies. The strike is field-selectable for fail-safe or fail-secure operation, allowing it to be configured either to unlock on power loss or to lock on power loss based on the project's safety requirements. Installers appreciate the non-handed design, which fits metal or wood frames and works on left- or right-hinged doors without modification. The 7501 has a slim 1-11/16" overall depth to fit standard ANSI 4-7/8" strike cutouts, and it comes with adjustable keeper shims and a trim enhancer plate to fine-tune alignment and cover rough cuts for a clean finish. A plug-in pigtail connector is included for fast, hassle-free wiring to the power source. For access control systems requiring door status monitoring, an optional latchbolt monitor (LBM) switch can be specified, which outputs whether the latch is engaged in the strike. Overall, the 7501's installer-friendly features reduce labor time and ensure the strike integrates smoothly into almost any cylindrical lock door opening, whether retrofitting an existing door or outfitting new construction.

Key Features & Benefits
  • Preload Release Function: Works well under normal door pressure (15 lbs) that would bind regular strikes, providing consistent unlocking even on warped and taunt doors.
  • 3-Hour Fire Rating: UL 10C listed for 3-hour fire doors (fail-secure) that can be used on fire rated escape doors maintaining the same code compliance and safety.
  • Heavy-Duty Stainless Steel: All-metal construction provides high strength and corrosion resistance for long-term durability in busy commercial settings.
  • High Holding Force: Tested to withstand 1,500 lbs static load and 70 ft-lbs of impact, deterring forced entry and assuring reliable security under attack.
  • Field-Selectable Fail Safe/Fail Secure: This device is easily configured to unlock during power loss or lock during power loss, having adaptability for many security and life-safety applications.
  • Dual Voltage Compatibility: Accepts 12 VDC or 24 VDC input power (continuous duty). Allows for simple integration across the many access control and power supply systems.
  • Non-Handed Design: Fits left-hand or right-hand doors. Slim strike body depth of 1-11/16" fits the standard ANSI frame preps making for an easy retrofit.
  • Quick Connect Wiring: Benefits from a plug-in connector pigtail for quick and secure wiring connection reducing installation time and ensuring secure electrical connections.
  • Installation Adjustability: Comes with keeper shims for horizontal adjustment, and a trim enhancer plate to cover gaps, allows for solid latch alignment and a proper professional installation.
  • Optional Latchbolt Monitor: An optional LBM switch provides a signal when the latch is secured and allows the monitoring of door status utilizing alarm or access control systems.
  • No-Fault Warranty: Comes complete with a 5 year no-fault warranty (with HES SmartPac III it actually can be 10 years), emphasising not only reliability, but also the manufacturers confidence in the product.
