There are two sets of power terminals on the termination card. Use one of the power terminals on the
termination card to connect to a 24 VDC power supply and if necessary 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.
Notes:
l Regional differences in power supply may impact on power connection. Please contact Xtralis
technical support for more information.
l Operating the detector when DC supply voltage is outside the voltage range of 18 VDC and 30 VDC
may cause damage to the device.
l The detector will not operate when the supply is reversed.
