Maintenance Free Access Control Battery 12V 12Ah VRLA Battery For Security System

The GP12-12 is a high-performance, maintenance-free Valve Regulated Lead-Acid (VRLA) battery utilizing advanced AGM (Absorbent Glass Mat) technology. Acting as the "Power Guardian" of security systems, it is specifically designed to ensure that electronic locks, controllers, and identification devices remain secure and operational during power outages, fire alarms, or mains failure.

Key Specifications

• Model: GP12-12
• Nominal Voltage: 12V
• Nominal Capacity: 12Ah (20HR)
• Design Life: 5 years
• Weight: 3.3kg

Why GP12-12 is the Ideal Energy Source for Access Control?

• Extended Standby Performance:
  In networked access control systems, controllers and readers (especially those with biometric or video features) consume power continuously. Compared to standard 7Ah batteries, the GP12-12 provides approximately 70% more capacity, ensuring the system remains operational for a much longer window during outages.
• Robust Drive for Electronic Locks:
  The core of access control lies in magnetic locks or electric bolts. These devices require stable current during engagement or actuation. The GP12-12 features an excellent instantaneous discharge platform, effectively preventing controller reboots or lock malfunctions caused by sudden voltage drops.
• Support for Multi-Door Controllers:
  In "2-door" or "4-door" multi-controller cabinets, a single GP12-12 can provide sufficient backup energy for multiple locks simultaneously, simplifying the spatial layout within the low-voltage power box.
• Fully Sealed & Leak-Proof:
  The starved-electrolyte design ensures no leakage even if installed in different orientations. It is perfectly safe for installation in office ceilings, reception cabinets, or wall-mounted power boxes.

Typical Application Scenarios

• Networked Access Control Hosts: Provides backup power for central management systems in multi-story buildings.
• Electronic Lock Backup: Widely used to secure magnetic locks, drop bolts, and Fail-Safe systems (emergency door release).
• Attendance & Recognition Terminals: Ensures that fingerprint or facial recognition terminals continue to log entry/exit data during power loss.
• Fire Linkage Systems: Guarantees sufficient power to forcefully release electric locks and open escape routes upon receiving a fire signal.
