Honeywell D902 3V DC Bell In One

The Honeywell D902 (formerly Friedland D902) is a traditional Bell-In-One wired doorbell system designed for domestic and light commercial applications. The kit combines a classic mechanical bell, door push, and bell wire to provide a simple, reliable door entry alert system that is easy to install and maintain.

Unlike electronic chimes, the D902 uses a mechanical underdome bell housed within a resonant white enclosure, producing a loud and clear ringing tone of approximately 80dB at 1 metre. This makes it suitable for properties where a traditional bell sound is preferred and where the chime needs to be heard clearly throughout the building.

The system is supplied as a complete wired solution, typically including the bell unit, bell push, and approximately 8 metres of bell wire, allowing straightforward installation for new builds, refurbishments, or replacement of older doorbell systems. The bell can generally be installed up to 9 metres from the push button, providing flexibility when positioning the bell inside the property.
