Model 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.
The OMA-VM500-3HT is easily
programmed over the phone.
Simply locate the unit in the area
where you want to measure the
temperature and relative humidity.
Plug in the phone line and the
power adapter 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.
