TTAW AUTO-WARNING TELLTALE

Based on our standard mechanical telltale, The Auto-Warning Telltale has been designed to provide a highly visible, immediate warning of excessive movement occurring in a rock-bolted tunnel or mine roadway

Two high-intensity flashing LED lights are configured to provide a warning once movement above an adjustable limit has occurred, making this product of particular value in dynamic mining and tunnel construction situations such as pillar extraction operations, where the workmen and equipment are operating close to a developing goaf, or in areas where visibility may be an issue

The TTAW has zero power consumption when not in alarm mode and therefore requires minimal service and maintenance, and can be inactive for a number of years and still operate successfully
