HES 9400 Slim-Line Surface Mounted Electric Strike
The HES 9400 is a slim, surface-mounted solution designed for rim exit devices with up to a 1/2″ latchbolt throw. It features a fully encased 1/2″ thick stainless steel housing, reducing frame cutting during installation. An included spacer plate helps accommodate varying door gaps. Best for retrofit projects where door frame modification is undesired and where a durable, vandal-resistant finish is important. Caution: ensure compatibility with existing strike hardware and verify door gap measurements before installation.
9400630 9400 Series Electric Strike (Replacement)
This model acts as a direct replacement for the HES 9400 family. It supports fail-safe and fail-secure operation modes and is designed to work with rim exit devices up to a 1/2″ latchbolt throw. It is compatible with HES 9400 series strikes and 12/24 VDC power supplies. Best for facilities upgrading a batch of existing 9400 strikes and seeking straightforward installation with comprehensive mounting hardware. Limitation: ensure voltage compatibility with current access control systems.
9600 Windstorm-Resistant Electric Strike
Certified to ANSI windstorm standards, this strike is designed for exterior doors in hurricane-prone or high-wind environments. It mounts surface-mounted with no frame cutting and is compatible with standard 3/4″ Pullman latches. Best for outdoor or harsh-weather installations where wind resistance and reliability are critical. Caution: wind-rated models may be bulkier than standard interior-only strikes; verify mounting space and frame compatibility.
HES 9600-630 Series Stainless Steel Fire Rated Strike
Designed to meet fire-rated requirements, this HES 9600-630 model is fully surface-mounted and built to endure severe exertions while maintaining glass-sleeve integrity. It works with rim exit devices and Pullman latches up to 3/4″ throw. Best for life-safety compliant doors in commercial settings. Limitation: heavier and potentially more expensive than non-fire-rated equivalents.
Seco-Larm SD-991A-D1Q Enforcer Mini No-Cut Strike
The Enforcer Mini No-Cut Strike converts a cylindrical lock into electronic access control with minimal frame cutting. It operates in fail-secure mode, keeping the door locked if power is interrupted. Best for retrofits where limited frame modification is possible and security during outages is a priority. Caution: ensure door and frame material compatibility with the no-cut requirement.
Buying Guide: Key Purchase Considerations
- Power supply compatibility: Verify whether the strike supports 12 VDC, 24 VDC, or dual voltage, and ensure your access controller matches.
- Door and latch compatibility: Check latchbolt throw (0.5″ vs 0.75″) and whether the strike is designed for rim exit devices or magnetic releases.
- Installation requirements: Surface-mount models usually require no frame mortising, but confirm frame material (wood vs metal) and available mounting space.
- Fire and wind ratings: For exterior or high-traffic doors, fire-rated and windstorm-rated options provide added safety and compliance.
- Fail-safe vs fail-secure: Fail-secure locks disengage when power is lost, while fail-safe unlocks; pick based on security policy and exit requirements.
- Maintenance and durability: Consider housing material (stainless steel preferred) and mechanical endurance (cycle ratings) for high-traffic doors.
- Compatibility with existing hardware: Some models are designed as direct replacements for specific series (e.g., HES 9400 or 9600); verify model-to-model compatibility.
Frequently Asked Questions
- What is a surface-mount electric door strike?
Answer: A device mounted on the door frame that interacts with an electric lock to control entry, typically without mortising the door. - Do these strikes require special power supplies?
Answer: Most operate on 12 or 24 VDC; verify your system’s power supply before purchasing. - Which model is best for wind-prone locations?
Answer: The windstorm-certified 9600-series options are designed for extreme weather performance. - What is the difference between fail-secure and fail-safe?
Answer: Fail-secure remains locked when power is lost; fail-safe unlocks under power loss. Choose based on safety and egress requirements. - Can I retrofit existing frames without cutting?
Answer: Surface-mount and no-cut designs minimize frame work, but always confirm door and frame specifications with the manufacturer. - Are fire-rated strikes necessary for all doors?
Answer: Fire-rated strikes are required on doors that must maintain fire integrity and life-safety standards in approved installations.
