The wake-up time is preset via the Remote Control. When the alarm time comes, the internal buzzer will be activated, if enabled, and will sound in a "soft" manner changing the frequncy of the "beeps" so that it does not sound annoying to the person who is just about to wake-up. The alarm can be silenced on command from the remote or it will expire by itself after several minutes.
The alarm can be restarted for the next day with a push of a button on the remote. A light on the display indicates if the alarm is set.

OPTIONS:
Option # 727 gives access to the contacts of the internal SPDT relay that can switch an external load like a Light, Buzzer, Horn or Siren at the alarm time.( 10Amp / 250V max. )
