The AlphaMax is versatile enough to be installed almost anywhere: at cell sites, communication towers, railroad crossings, refrigeration systems at any facility where it's important to have immediate notification of changing conditions.

Dial up remote alarm detection system reports directly to any pager

The most appealing feature of the AlphaMax is that you don't need any extra equipment not even an alarm master to monitor your remote sites. This dial up alarm detection system can report directly to any numeric or alphanumeric pager, putting a complete remote monitoring solution directly in your pocket or belt clip.

You have several options for configuring how the AlphaMax dial up remote reports alarms:

Unipolar or bipolar operation: Each alarm point can be configured to report only alarm sets (unipolar operation) or both alarm sets and clears (bipolar operation).

Alarm qualification times: You can set an alarm qualification time to filter nuisance alarms (temporary and oscillating conditions). The redial option configures the AlphaMax to redial

Redial option: The redial option configures the AlphaMax to redial the primary pager number up to 15 times if an alarm is acknowledged.

Primary and backup pager numbers: Even the best on-call technician occasionally fails to respond to alarms. A backup pager number ensures that if the first technician doesn't acknowledge an alarm, a second technician or a supervisor will be paged.

The AlphaMax isn't limited to pager notifications, however. The dial up remote alarm detection system can also forward alarms to ASCII terminals for recording alarm events. And if you want to integrate your AlphaMax sites with the rest of your network monitoring, the AlphaMax can report to DPS' master unit, the T/Mon Remote Alarm Monitoring System.

Control from any phone

To acknowledge alarms and control the AlphaMax, simply call it up. The dial up remote alarm detection system features built-in support for DTMF control, so you can operate it remotely just by punching in touch tone codes, like having a voice mail system for accessing your alarms.

Using the DTMF control, you can request status reports of all alarm points, acknowledge alarms, and operate control points.
