The OMA-VM540 monitors the temperature of up to four areas
and up to four 12 Vdc powered inputs. The OMA-VM541 monitors
the temperature of up to four areas and up to four 24 Vac powered
inputs. The OMA-VM540 and OMA-VM541 will call and alert you
with a voice message or a pager alert when a temperature is out of
limits and your valuable equipment is in danger of being damaged.
The OMA-VM540 and OMA-VM541 will call you if power is lost at any
input or the auxiliary alarm input becomes active.
Remote Status Checking
The OMA-VM540 and OMA-VM541 can be called at any time to check
the status of any input.
Emergency Phone Calls
When a temperature input is out of programmed limits, a
power input changes from its normal state, the power at the
wall-mount power adapter is out, or a contact closure occurs on
the auxiliary dry contact input the OMA-VM540 and OMA-VM541 will
dial all programmed phone numbers until contact is made. If contact has
not been made after dialing all phone numbers, the OMA-VM540
and OMA-VM541 will wait twenty minutes and then begin calling
again.
This sequence is repeated until contact is made. When the
OMA-VM540 and OMA-VM541 is calling a standard voice number,
it will play the recorded alarm message and the current alarm
condition. The OMA-VM540 and OMA-VM541 will then prompt the
user to enter the PIN. When the correct PIN is entered, contact has
been made.
The OMA-VM540 and OMA-VM541 will stop calling until a new alarm
condition occurs. When the OMA-VM540 and OMA-VM541
calls a pager number, it will transmit the programmable Local ID Number
for display on the pager screen.
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 and power
input parameters remotely.
