The SIGA-MDM Digital Message Module provides the ability to add custom prerecorded voice messaging to Edwards’ Network and Non-network systems. A microphone/line-level audio input stereo jack along with an audio output stereo jack for monitoring with headphones or amplified speakers are provided. Creating and reviewing messages is straightforward using MDM’s onboard record and playback switches. Programming in the Signature Data Controller provides all control instructions. Extra wiring for monitoring or controlling circuits is not required.

The SIGA-MDM is shipped with two factory recorded messages. These standard messages can be changed on-site using the MDM’s recording capabilities.

The SIGA-MDM is part of the UIO family of plug-in Signature Series modules. It takes advantage of the modular flexibility and easy installation that characterizes all UIO modules. Two- and six- module UIO motherboards are available. These can accommodate individual risers for each on-board module, or shared risers in any combination with their UIO modules. All wiring connections are made to terminal blocks on the motherboard. UIO assemblies may be mounted in either Edwards cabinets, or standard electrical enclosures.
