The OMA-VM500-3HT
is a full-featured monitor and alarm
system that monitors temperature
and relative humidity and power
status wherever the unit is located.
These systems can dial up to four
phone numbers, and the integrated
voice tells you the temperature and
percent relative humidity levels and
whether the power is on or how
long the power has been off. You
can also call the unit at anytime and
hear a status report that gives
you an update on the conditions
at your facility.

and turn the unit on. Call the unit
from another phone or cell phone
and follow the spoken instructions
to program the temperature and
humidity limits and the emergency
phone numbers. The system is
now programmed and is monitoring
temperature, relative humidity and
power at your facility.
