Description

The NESCO GP-504 is a classic, open-gong General Purpose Bell designed for clear, audible signaling in residential and commercial environments. Featuring a 2 1/2″ polished chrome gong, this unit produces a bright, traditional ringing tone that is easily distinguishable from background noise. Its compact footprint makes it an ideal choice for door alerts, telephone extensions, or localized “call” signals in offices and small shops.

Engineered for flexibility, the GP-504 operates efficiently across a broad low-voltage range: 8-16V AC or 3-6V DC. This versatility allows it to be powered by standard doorbell transformers or battery-operated systems without the need for specialized hardware.
