12V 24Ah VRLA Public Broadcast Battery For Security System

The GP24-12 is a Valve Regulated Lead-Acid (VRLA) battery manufactured using high-purity AGM (Absorbent Glass Mat) technology. This model is specifically designed for medium-to-large scale audio engineering, emergency broadcasting in tunnels or stations, and smart campus broadcasting control systems. Its substantial 24Ah power reserve easily handles the demanding electrical requirements of high-power amplifiers operating at full load.

Why GP24-12 is the Performance Foundation for PA Engineering?

• Superior Dynamic Headroom:
  When a PA system broadcasts sudden announcements or powerful background music, the amplifier's instantaneous current demand is extremely high. The 24Ah battery features lower internal resistance, providing a more robust transient response than standard batteries, ensuring that sound remains clear and undistorted during dynamic peaks.
• Extended Emergency Standby and Runtime:
  In large public venues (such as stations or stadiums), fire safety regulations require the broadcasting system to remain functional for extended periods after a power failure. The GP24-12 offers nearly 40% more capacity than common standard sizes, ensuring evacuation instructions never cut out at the critical moment.
• Support for Multi-Zone Amplifiers:
  In complex systems, a single power source often needs to support multiple zone amplifiers. The high-capacity nature of the GP24-12 allows it to act as a centralized backup, reliably driving multiple sets of ceiling speakers or outdoor sound columns.
• Excellent Power Purification:
  As a DC backup source, the GP24-12 acts as an exceptional filter when integrated into the circuit. It effectively suppresses "AC hum" caused by mains fluctuations, resulting in clearer, richer voice announcements and better background music fidelity.

Typical Application Scenarios

• Transportation Hubs: Airports, subways, and railway stations requiring continuous, long-term broadcasting.
• Emergency Warning Systems: Civil defense, large-scale industrial dispatching, and fire-linked evacuation systems.
• Smart Campus Audio: Supports automated bell systems, daily exercises, and sound reinforcement for large outdoor assemblies.
• Long-Distance Constant Voltage Systems: Provides stable power compensation to offset losses caused by long-distance line transmission.
