The OMA-VM500-7 and
OMA-VM5000-7-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.
Simply locate the unit, plug in the
phone line and the power adapter,
turn the unit on and then call the
unit from another phone or cell
phone.
Follow the spoken instructions and
instructions in the operator’s manual
to program the phone numbers
where you want the dialer to call in
case of an alert condition and the
upper and lower temperature limits.
Then hang up by pressing the “0”
key on your phone until the unit
says “Good-bye.” The system is
now programmed and is monitoring
your facility for temperature, power
status and door status.
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.
