Power Up
Caution:
Powering up the system must be done by VESDA accredited personnel.
Attention :
La mise sous tension doit être effectuée par du personnel accrédité VESDA.
7.1
Power Up the System
a. Remove the 1.6A fuse on the termination card.
b. Turn on the power to the detector.
c. Check the DC voltage at the
Power
terminals on the termination card is between
18 VDC to 30 VDC
.
Disconnect the power immediately if the supply voltage is above
30VDC
or less than
18VDC
and
troubleshoot the fault.
d. Replace the fuse when the measured voltage is OK. The system takes approximately 15 seconds to
power up during which time an LED test sequence is performed.
e. If the system fails to power up:-
l
Check all the power wires are securely connected to the Power terminals.
l
Check the polarities of the power wires are correctly terminated.
l
Check for a blown fuse on the termination card. Refer to Figure 6-5 for the fuse location.
Note:
The detector may show faults immediately after power up and this is normal. Reset the unit by
pressing the RESET switch on the front cover of the detector to unlatch the relays and fault lights.
The fault light on the front cover will light up and this is normal. Proceed to Chapter 8.
