Its flexible interface allows for integration with security and alarm systems, and CCTV, especially when utilizing the optional bolt position indicator.

2. Safety Information

Please read and understand all safety instructions before installing or operating the Sargent & Greenleaf 6120 Electronic Safe Lock. Failure to follow these instructions may result in property damage or injury.

• Battery Safety: While batteries are not included with the lock, proper battery installation and maintenance are crucial. Use only high-quality alkaline batteries. Replace batteries promptly when low to avoid corrosion or operational issues. Leaky batteries can damage the lock's internal components.
• Penalty Lockout: The lock features a penalty lockout mechanism. If four or more incorrect codes are entered consecutively, the lock will shut down for five minutes. Do not attempt to force entry during this period.
• Master Reset Code: Be aware that some locks may come with a pre-programmed Master Reset Code. It is critical to understand if your specific lock has such a code and to manage its security. If a Master Reset Code exists and is not changed from its default (e.g., 123456#) after installation, it could potentially compromise the security of your safe. Consult the manufacturer's specific instructions regarding master codes and their management.
• Professional Installation: For optimal security and functionality, professional installation by a qualified locksmith or safe technician is highly recommended.
