Electric Drop Bolt Lock, 12V / 24V NC Mode Fail Secure Lock with Adjustable Delay Outer Layer Mounted for Metal/Wood/Fire Doors
- [Fail-Secure NC Running] The electric drop bolt lock defaults to locked position during power outages, ensuring continuous security. Visual LED indicators (red=unlocked, green=locked) provide instant status checks without compromising access control protocols.
- [Accuracy Delay Customization] Users configure locking delays to 0s, 3s, or 6s via the 12V/24V system, accommodating different door closure speeds. This prevents premature engagement that could damage door frames or interrupt foot traffic .
- [Universal Door Compatibility] Designed for outer layer mounting on wood, metal, and fire-rated doors up to 2.5 thick. The compact 7.9 x 1.4 profile integrates discreetly with existing door hardware while supporting remote control integration (accessory sold separately).
- [Anti-Tamper Aluminum Build] Crafted from wear-impervious aluminum alloy, this electric mortise lock withstands 500lb+ forced entry attempts. The polished finish resists weathering and maintains appearance in high-traffic environments like schools or hospitals.
- [Simplified Installation] Includes pre-drilled templates and stainless steel screws for tool-no mounting. The dual-wire terminal accepts standard 12-24V DC power supplies, while the 0.59 bolt throw ensures secure engagement with most strike plates.
