Description

The NESCO GP-505 is a high-output, open-gong General Purpose Bell designed for applications requiring a louder, more resonant signal than standard smaller bells. Equipped with a 4″ polished chrome gong, this model produces a deep, authoritative ringing tone that carries effectively across larger spaces, making it an excellent choice for noisy commercial environments, school hallways, or small industrial workshops.

Engineered for broad compatibility, the GP-505 operates reliably across a low-voltage spectrum of 8-16V AC or 3-6V DC. This dual-voltage capability allows it to be integrated easily into existing building signaling systems, security circuits, or battery-powered emergency alerts.
