Trackside warning System


Trackside Warning System (TWS-02) is designed for use by Rail & Road Maintenance Works. It ensures the Sentry does not leave his/her post and remains vigilant by setting up an invisible zone the Sentry must remain inside. If the Sentry wanders outside of this zone the RF linked Track/Roadside Warning Units (TWU’s) go into an alarm state. The Sentry can also raise an Alert by pressing the ‘Buddy AlertTM’ Button this is then relayed to all workers bringing their attention to any potential danger. The system is fail-safe with failure of any configured unit causing the system to go into an Alert state.
