Power Source
There are two sets of power terminals on the termination card. Use one set to connect to a 24 VDC power
supply and if required loop out to another device via the second set. The detector has reverse polarity
protection to minimize the risk of reverse power connection to the detector. For further information, refer to
Section 3.1 on page 11.
Caution:
The VESDA VLP detector will not operate when the supply is reversed.
Attention :
Le détecteur VESDA VLP ne fonctionnera pas avec une alimentation inversée.
Note:
Operating the detector when DC supply voltage is outside the voltage range of 18 VDC and 30
VDC may cause damage to the device.
