The signal under 0.75 sec will put the IZ8018 in standby mode. • MELODY STOP The melody does not stop until it plays to the end of the melody even if alarm signal is stopped. Though the alarm signal is longer that the melody signal the melody does not repeat. If the melody is needs to be stopped midway it can be done by pushing either S1 or S2. MELODY SOUND |
