Macurco DVP-120C Manual
DVP-120C displays the address of the detector with calibration due warning. If there are more than one detector
with calibration due warning, then display scrolls every 5 seconds to display all detectors with calibration due
warning.
During Calibration Due Warning, the warning LED will be ON. Buzzer, Horn and Strobe of the panel will be activated
based on Warning Signal Configuration in CONFIGURE SIGNAL.
When the HUSH key is pressed, the internal buzzer will be silenced. 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. Silence period is dependent on time left to calibration. Following table

When all indicators have been silenced, the display will show that calibration due warning indication have been
silenced for corresponding silence period. After approximately 5 seconds the display will return to normal mode.
Only a calibration due warning with lower silence interval (refer Table 4-2) will reset the HUSH and panel will go back
to state indicating Calibration Due Warning.
When in normal mode, for detectors with Calibration Due Warning silenced panel will display current gas reading
alternating with "Cal. Due" every second.
