Omega Engineering Four Zone Temperature OMA-VM520-DCP - Manual (Page 6)

Accessing the Four Zone Temperature Monitor over the phone
1 From another phone line call the Four Zone Temperature Monitor and Alarm.
The device will pick up after the programmed number of rings (Default is 1).
2 To access all functions, enter the 4-digit "Full Access" PIN. (Factory default
is 0000). To access only the "Acknowledge Only" functions, enter the 4-digit
“Acknowledge Only” PIN 1234.
The "Acknowledge Only" functions are:
A) Confirming Alarm Conditions Remotely
B) Checking Sensor Inputs Remotely
3 You will hear the Main Menu options:
Each temperature sensor has four (4) programmable parameters as well as a
programmable temperature correction.
Sensor Identification Message. The Sensor ID message will be played when
the Four Zone Temperature Monitor and Alarm is reporting the status of that
Sensor.
Sensor Low and High Temperature limits. The low and high temperature limit
values are programmed in degrees. When a sensor's temperature exceeds ei-
ther the high or low limit for longer than the programmed callout time delay, that
sensor will be in alarm condition. For OMA-VM520-DCP units this value can also
be programmed using the Data Capture Software.
Sensor callout time delay. A sensor's temperature must be out of limits for
greater than the callout delay time for the sensor to be in alarm condition. For
VM520-DCP units this value can also be programmed using the Data Capture
Software.

When does the Four Zone Temperature Monitor and Alarm callout?
The Four Zone Temperature Monitor and Alarm will callout when any sen-
sor/input is in an alarm condition and has not been confirmed.
When an alarm condition first occurs, the Four Zone Temperature Monitor
and Alarm turns on the alarm relay and buzzer, and then waits two minutes
to allow local personnel time to react to the alarm.
When is a sensor/input in alarm condition?
When a temperature sensor has been out of limits for greater than the pro-
grammed time delay.
When a temperature sensor opens or shorts after having been connected.
When a door sensor has been open longer than the programmed time de-
lay.
When the power has been out for greater than five minutes.
What happens when the Four Zone Temperature Monitor and Alarm
calls?
1
The Four Zone Temperature Monitor and Alarm will dial the contact
number exactly as it was programmed.
► If the contact number was programmed as a pager number (* is the
first digit. The Four Zone Temperature Monitor and Alarm will dial all
digits following the *.
2 The Four Zone Temperature Monitor and Alarm will wait for a person or
voice mail system to answer the call.
3 The Four Zone Temperature Monitor and Alarm will beep while it waits
for a person to stop speaking or the voice mail system's outgoing mes-
sage to stop.
4 For voice contact numbers, the Four Zone Temperature Monitor and
Alarm will play the recorded personal identification message.
For pager contact numbers, the Four Zone Temperature Monitor and
Alarm will print the Local Identification number on the pager screen.
The Four Zone Temperature Monitor and Alarm will then hang up and
call the next programmed contact number.
5 The Four Zone Temperature Monitor and Alarm will report any alarm
conditions (i.e. “Warning, Sensor 2, “sensor 2 recorded message”, is
89 degrees and has been out of limits for, x hours and y minutes.
6 The Four Zone Temperature Monitor and Alarm will ask for the PIN
number.
Once the PIN number has been entered, the Four Zone Temperature Moni-
tor and Alarm will not call again because the current alarm condition has
been acknowledged, unless the alarm still exists and the reminder call has
been enabled.
If the correct PIN number is not entered within 4 seconds the Four Zone
