Electronic Chime CROMA 100A

CROMA Electronic Doorbell with 17 Polyphonic Melodies

The CROMA 100 A electronic doorbell offers modern functionality and a sleek design. With 17 polyphonic melodies, as well as the option to select an alarm sound, this signaling device flexibly adapts to your needs – ideal for homes, offices, or commercial properties.

Thanks to the 2-way call differentiation, different signals can be clearly distinguished from each other. Both channels can be set together via two trigger modes (single or continuous). The volume is individually adjustable and reaches up to 86 dB(A).

A special highlight is the practical SILENCE function for quick one-button muting. Operation is extremely energy-efficient: with minimal standby consumption and a battery life of up to 3 years (when using 4x LR14/C batteries), the doorbell is ideally suited for long-term use. An acoustic low-battery warning provides additional security.

Optional external power supply (8–12 V AC/DC) and triggering via potential-free contacts offer flexible application options. The doorbell is also ideally suited for mixed installations or renovations. In addition, parallel connection to other CROMA doorbells or electromechanical doorbells is easily possible.
