The AD2 is an Alarm Dialler with Voice message, suited to operation with all Phasefale alarm and monitoring systems. It can automatically dial up to
 6 numbers and playback the recorded  alarm message (of up to 16 seconds) in high quality sound.
The message can be acknowledged to prevent further dialling.  

AD2 is simple to program and requires minimal installation and so directly solves the problem of forwarding the vital food loss alarm signal generated by
JouleTemp, JouleAlarm, TACm or Presscon. It is supplied complete with PSB30 battery backup system for operation during power failure.
