The M30 Auto Dialler can now send SMS Alarm Messages instead of or as well as Real Speech Messages.
The upgrade is available to be supplied with a new Auto Dialler or as a retro upgrade to a currently installed machine.
This is ideal for people who want a visible alarm message instead of an audible message or for logging alarms.
But you need to bare in mind that SMS messages are not a guaranteed service i.e. the message might arrive instantly, in 5 minutes or 5 hours. Also if your phone is out of reception when the SMS message is sent very often there is an extended delay for delivery.
