The Sentry is designed to monitor sound levels and provide a trigger when a preset sound level is exceeded, this trigger will normally be used to trip a contactor removing the mains power supply to the music system. When the Sentry trips the contactor there is a short (about 3 seconds) delay before the system can be reset, before pushing the reset button always check that it is safe to do so (eg amps turned down so no sudden surge).
