The DMM-618 B is a highly versatile digital message module designed to play MP3 audio files for both security and commercial applications. It can operate in two distinct modes: as a monitored voice memory module for alarm systems or as an advertising message device in stores, supermarkets, restaurants, or medical offices.

With the ability to store up to 18 messages, the device allows triggering via six front-facing buttons or through 18 dry-contact inputs on the rear. An integrated LCD display, message priority control, and reset button provide clear and reliable operation. Additional features such as a priority contact, transformer-isolated audio output, and a fault monitoring relay ensure professional integration in public address or emergency alert systems.

The serial output allows control via RS-232, for example in combination with the TIF-404 C interface. Supporting SD cards up to 64 GB and powered by a 24 V DC supply, the DMM-618 B offers outstanding flexibility and future-proof performance.
