Powering Up

After installing the detector it is necessary to power up the system. The power up sequence lasts
approximately 15 seconds.
The VES-A00-P detector does not have a power switch i.e it is an "always on" device which is activated by
applying powered cabling to the power input terminal on the main board (Figure 4-33). This process must only
be performed by Xtralis accredited personnel.
If the system fails to power up, check all power wires are secured to their terminals and that the polarity is
correct.
On power up:
The Power LED illuminates and the detector runs a series of self-diagnostic tests.
l
If there is a fault, the Fault LED illuminates. To identify the fault, check the Active Event List for the
l
detector using Xtralis VSC.
The aspirator starts up and air may be felt flowing out of the exhaust port.
l
It is normal for the detector to display airflow faults immediately after the first power up and until the air flow
normalization step is done. Reset the detector by pressing the reset button on the front of the unit. This will
unlatch the relays and turn off the Fault LED. Any remaining faults will cause the Fault LED to illuminate
again. Proceed with the preliminary system check.
