Potter Electric 70V-1000 70V Extender Dca Amplifiers

Product Description

The POTTER ELECTRIC SIGNAL CO. US 70V-1000 is a 70-volt signal extender designed for use with DCA amplifiers in voice evacuation systems. It expands the reach of a DCA amplifier's 70V audio output, allowing the system to serve additional speaker zones or extend signal distribution across larger coverage areas. Licensed fire alarm and life safety technicians install this component as part of a compliant voice evacuation audio system. Its stacking capability supports modular system expansion without requiring a separate standalone amplifier for each zone.

The 70V-1000 is suited for commercial and institutional voice evacuation installations where a DCA amplifier serves as the primary audio source. Typical applications include office buildings, schools, healthcare facilities, and other occupancies requiring mass notification or emergency voice communication systems. The stacking feature makes it a practical choice when a single DCA amplifier must drive a larger number of 70-volt speaker loads than its base output supports.

Key Features

• Extends 70-volt output from DCA amplifiers to additional speaker zones
• Stacking design allows modular expansion of voice evacuation audio distribution
• Designed for voice evacuation system applications in commercial and institutional settings
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style extender for use with DCA series amplifiers in 70-volt voice evacuation systems.

Installation Notes

Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and applicable local codes. De-energize the amplifier and voice evacuation panel before connecting or disconnecting any components. Verify that total 70-volt speaker load on the extended circuit does not exceed the amplifier's rated output capacity. Follow the manufacturer's wiring and stacking sequence documentation to ensure proper system operation.
