Figure 3-4 Normal System Display

The display shows the day of the week and the time of day, in 24-hour format. It also shows the status of one of the relays, R1 in this example, and the type and indicated gas concentration of one of the configured sensors, S01 is a CO sensor indicating 5 ppm in this example.

Notice in Figure 3-4 that the digits 01 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 sensor to display.

Figure 3-5 Sensor prompt

In this example, the first digit entered was 1. Since the DVP-120 can handle 12 sensors, the first digit for a sensor number is either 0 or 1. The leading zero must be entered when selecting a sensor less than ten. When the second digit is entered, the normal display will be restored; showing the type and value for the selected sensor.

As mentioned above, the left and right scroll keys will display the next (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 the sensor is indicating a trouble condition the gas reading will be replaced by the word TROUBLE.

3.1.4 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.

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.

When all indicators have been silenced, the display will show that alarms have been silenced for five minutes. After any key press (or five seconds), the display will return to normal mode.
