When the HUSH key is pressed, the internal buzzer will be silenced for eight (8) hours. If the horn or strobe turn on delays have not finished then they will also be silence. 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 trouble indications have been silenced for eight hours. After five seconds (or any key press), the display will return to normal mode.

3.2Ventilation control

The ventilation control function operates independently from the alarm function. It provides the ability to configure the DVP-120 for control of one to three zones. Each zone can respond to gas levels indicated by one or more of the three types of sensors, with configurable turn on and turn off concentrations for each gas type. Each zone can also be controlled based on the time of day and/or two of the sensor types.

Each zone can be configured to control one, two or all three of the relays and the external horn and strobe if desired. When more than one zone is controlling a relay it only takes one zone to activate the relay, but all controlling zones must release the relay before it will turn off.

Each of the relays, horn and strobe have independent turn on delays (to ignore short duration transients) and turn off delays (to ensure minimum run times for fans that must run for internal cooling).

3.2.1Zone Signal Display

When a zone is controlling the horn or strobe and they turn them on, the panel will enter ZONE SIGNAL mode during which the horn and/or strobe will be turned on and the LCD will show the zone that is signaling.

The display will cycle through all zones that are controlling the horn or strobe and are signaling, at five seconds per display. Pressing any key (except HUSH) will advance the display to the next zone that is signaling.

When the HUSH key is held for three (3) seconds, the horn and/or strobe will be silenced for fifteen (15) minutes. When silenced, the display will show that zone signals have been silenced for fifteen minutes. After any key is pressed (or five seconds) the display will return to normal mode.
