Had to replace a lamp, but the same was no longer available. Great advice, found a suitable replacement and delivered it quickly.

Grothe Door and Home Communication

Grothe GmbH from Porta Westfalica specialises in door communication and home technology, offering the complete programme for door bell systems: from the bell pushbutton through the transformer and bell to the handset as indoor station. Single-family home intercom sets make new installation straightforward with matched components. Supplementary products such as motion detectors, cameras and impulse relays round out the range for complete home electrical installation.

  Installer's tip: Bell transformers for intercom systems must be rated for the power demand of all connected components. With multiple bell pushbuttons or a combined audio intercom, small standard transformers are often insufficient. An undersized transformer causes voltage drops during ringing and results in intercom malfunctions.

FAQ: Grothe

What does Grothe manufacture?

Grothe GmbH develops door and home communication technology: bell pushbuttons, handsets, intercom systems, bell transformers, chimes and electric bells, and supplementary components such as motion detectors, impulse relays, dimmers and safety transformers.

What is a Grothe impulse relay?

An impulse relay toggles its output on and off with each brief current pulse, allowing lighting to be controlled from multiple points using simple pushbuttons. It is particularly suited to stairwells and corridors with many control points.

What is the difference between an electric bell and a two-tone chime?

An electric bell produces a mechanical ringing sound via an electromagnetic vibrating armature. A two-tone chime produces a softer, two-note sound and is generally considered more pleasant for residential use.
