The Giant Voice® landline module is the perfect solution for warning system communication over cable link over long distance. It provides two 600 Ohms balanced audio outputs for best possible signal to ensure that the warning tones and voice messages are clear and intelligible. 

Depending on your control center the GV-LLM has the ability to both activate and monitor your warning system.

The one-way option simply controls the warning system, while the two-way option controls the system and reports status back to a central control point for easy maintenance and for insurance that your warning system is up and running at all times.
