Macurco DVP-120C Manual

4 Operations

4.1 Power up

When power is first applied to the DVP-120C, a few simple self-tests will be performed, and the system will cycle
through all status lights, and display the system model and firmware version number (Figure 4-1). The system will
then proceed to normal mode if the operating parameters have been entered.
Each time the unit is turned on it performs a self-test, which activates the audible and
visual alarms. If the self-test fails, or all the alarms do not activate, do not use and
contact Technical Support at 1-844-325-3050.

4.2 Initial Operating Mode

If the user has not entered any parameters, the system WILL NOT be controlling the ventilation system. The relays
WILL NOT actuate, and the horn and strobe outputs WILL NOT be powered. The power status light will show
NORMAL (steady green) and the system will immediately enter the CONFIGURATION mode, see section 4.2 for
details to set the configuration parameters.
If a valid set of configuration parameters have been entered, the panel will wait for all sensors to warm up. During
this time, the display will show a count-down, minutes and seconds, until the end of the warm-up period, (Figure 4-
2).
During the warm-up period, the keypad will be locked. When the warm-up period ends, the LCD will start showing
the normal display.
