    SOLA 4000 - Operating Panel 5 Remote Panel Communication timing When an alarm condition occurs, the Remote Panel calls the first programmed number. If the line is busy and only one number is to be called, the Remote Panel waits for 5 minutes and, if the alarm condition is still present, it tries to call the number again.
