Kidde - Edwards 270PZO1248AD Piezo Sounder 12-48V

Product Description

The KIDDE - EDWARDS 270PZO1248AD is a piezoelectric electronic sounder designed for use in fire alarm and life safety signaling systems. Operating across a wide voltage range of 12 to 48 volts, this unit accommodates a variety of panel and power supply configurations without requiring separate models for different voltage tiers. Finished in gray, it suits surface-mounted installations in commercial and light industrial environments. Licensed fire alarm technicians and low-voltage electricians are the primary trade professionals who specify and install this device.

The 270PZO1248AD is suited for commercial fire alarm notification applications where an audible piezo sounder is required. Its wide input voltage range makes it adaptable for use with standard fire alarm control panels and auxiliary power supplies operating at 12 or 24 volts DC, as well as systems running up to 48 volts. It is appropriate for office buildings, light industrial facilities, and institutional spaces where a compact, low-profile audible notification device is needed.

Key Features

• Wide operating voltage range: 12 to 48 volts for flexible panel compatibility
• Piezoelectric sounder technology — no moving parts for reliable audible output
• Gray finish suits standard commercial surface-mount installations
• Sold as a single unit (EA) for straightforward procurement and replacement

Compatibility

Designed as an OEM-style audible notification device compatible with fire alarm and life safety control systems operating between 12 and 48 volts DC.

Installation Notes

Installation should be performed by a licensed fire alarm technician or low-voltage electrician in accordance with NFPA 72 and applicable local codes. De-energize the fire alarm control panel and associated power supplies before wiring or mounting the sounder. Verify polarity and system voltage compatibility prior to reconnecting power. Follow the manufacturer wiring diagram and conduct a full system functional test after installation.
