Alarm Status Display - Macurco DVP-120C User Instructions

Macurco DVP-120C Manual
Notice in Figure 4-4 that the digits 0 1 are underlined; this indicates that the digit keys can be used to jump directly
to another sensor's status. When the first digit is pressed, the display will prompt for the second digit of the target
sensor.
In this example, the first digit entered was 1. Since the DVP-120C can handle 99 sensors, the sensor number must be
entered in a two-digit format. For single digit number (1-9) the first digit entered would be 0 (zero). When the
second digit is entered, the normal display will be restored; showing the type and value of the selected sensor.
As mentioned above, the left and right scroll keys will display the next or previous relay's status. The display will also
change the underline to indicate that the digit keys (zero, one and two) can be used to jump directly to a particular
relay. Since only one digit is needed to select a relay, the system does it immediately rather than prompting to show
the relay.
If the sensor is indicating a gas level that is greater than the alarm or warning levels, the gas reading will alternate
with the words ALARM or WARNING as appropriate. If a sensor fails, a connection is lost or the panel itself detects a
failure of its own, the panel will enter TROUBLE mode and the gas reading will be replaced by the word TROUBLE
(the TROUBLE status condition is discussed in section 4.7 Trouble Status Display).

4.5 ALARM Status Display

When any sensor indicates a gas level that is at or above the configured alarm level for the sensor, the panel will
enter ALARM mode, during which the internal buzzer will sound, the alarm lamp will be red and the LCD will show
the sensor type and channel number.
The display will cycle through all sensors that are signaling alarm levels, at five seconds per display. Pressing any key
(except HUSH) will advance the display to the next sensor that is signaling an alarm level.
Do not cover or obstruct audible alarm opening or visual alarm LED. Doing so may
adversely affect product performance.
If an external horn and/or strobe are connected and configured to signal an alarm condition, they will also sound
when an alarm condition occurs, after a delay if that configuration option is used.
When the HUSH key is pressed, the internal buzzer will be silenced for five (5) minutes. If the horn or strobe turn on
delays have not finished, then they will also be silenced. If the delays have finished the HUSH key must be held for
three (3) seconds in order to silence the horn and strobe.
