OMA-GUARD-IT as a direct substitute
The OMA-VM500-7 and OMA-VM500-7-DCP dialers
monitor power, 2 door status inputs and up to eight independent
temperature zones and dials up to eight phone or pager numbers if the
temperature in any zone goes out of limits, if there is a power outage
or a door is opened. The integrated voice tells you which
zone is out of limits and the current temperature. You can call the unit at
any time to hear a report on the temperature of any zone, power
status and door status. All programming is accomplished
over the phone following simple voice instructions. These dialers are
easily programmed over the phone.

Ethernet Data Collection
The optional Ethernet data collection package allows you to
remotely check the dialer status with a standard web browser.
Using this package you can view real time data, view historical data,
automatically send alarm emails to key personnel that specify the exact
location and cause of the problem, maintain secure data files, easily
create and print graphs over specified time periods for any data
and also program temperature limits remotely.
