It provides reliable security without compromising fire safety compliance in appropriate door assemblies.
For buildings requiring fire resistance, the 9500 delivers certified performance while remaining compatible with standard rim devices. When planning installations, verify the door and frame are rated for fire access, and ensure power supply compatibility matches the building’s electrical system to avoid nuisance faults during an alarm sequence.
Buying Guide: Key Considerations and Comparisons
Select a surface mounted electric strike based on door type, frame construction, and security goals. Consider the following perspectives:
- Fire rating: If your door is part of a fire-rated wall or corridor, prioritize models with NFPA compliance and fire-rated certifications, such as the HES 9500.
- Latch compatibility: Check latchbolt throw (0.5″ to 0.75″) and compatibility with Pullman latches to ensure proper engagement.
- Frame and installation: Surface-mounted designs simplify retrofits but confirm space, mounting dimensions, and spacer requirements to avoid frame cutting.
- Voltage and wiring: Dual voltage (12/24 VDC/VAC) models offer flexibility across systems. Plan for power supply availability and wiring paths.
- Durability and environment: Windstorm resistance and stainless steel housings are beneficial for exterior doors or high-traffic corridors.
- Maintenance: Look for tamper resistance, ease of service, and compatibility with existing door hardware to minimize maintenance downtime.
- Certification: Seek ANSI/BHMA Grade 1 ratings and UL listings where required by code for commercial installations.
