Grothe CROMA 100A ws/sw

With 17 appealing polyphonic melodies, you can choose your desired sound. Additionally, there is the option to switch between melody and an alarm tone, depending on your individual requirements. The gong offers two trigger modes that can be set for both channels: continuous operation and single operation. The volume is adjustable and can be increased to an impressive 86 dB(A). The dual call distinction allows for differentiating between various events or alarms.

For added user-friendliness, the signal generator features a SILENCE function that enables easy one-button muting. Despite its powerful features, this signal generator has minimal standby loss, significantly extending battery life. An acoustic notification is provided when the battery is low. Under normal operating conditions, the battery life is approximately 3 years, ensuring durable and reliable use.

Our signal generator is the optimal choice for flexible and effective acoustic notifications.
