PSTN and GSM Auto-Dialers

The relay controlled PSTN and GSM auto-dialers add an additional level of alert notification. The units are especially ideal for notifications in the unusual event of a network failure and also for alert notifications from remote locations where a network connection is not available for SNMP or email alerts. Battery back-up ensures that the auto-dialer can still deliver alerts even if its power source is lost. The dialer can be programmed to call up to nine different phone numbers and play a pre-recorded message to each person who answers, until the message is acknowledged. The dialer contains two triggers. Each trigger can have its own pre-recorded message.


Both dialers connect to the relay output port on an environmental monitor. The GSM receives a SM card and the PSTN uses a standard telephone line.
