XNX Universal Transmitter
Section 2 - Installation and Operation 43
2.2.8 mV Personality Wiring
XNX Universal Transmitter with the mV personality Board allows
interface to HA’s Multi Purpose Detector (MPD) and field proven
705 and Sensepoint devices�
Caution:
See Section 6 - Specifications to ensure that the
transmitter and the mV sensor have the appropriate approvals prior
to commissioning.
Caution: Verify that the mV sensor being installed has compatible
threads (3/4 NPT or M25).
Read Section 2�2 which defines the XNX power and 4-20mA
output connections that are common to all personalities�
Connections from the mV Sensor to the XNX are made via a
single pluggable terminal block allowing ease of installation and
service� Honeywell Analytics recommends that an 8” (203 mm)
service length for wiring be maintained� The wire colors for the
connections for each sensor type are shown in the following
Wire Color from Sensor table�
Verify that wires for 4-20mA outputs are routed away from
sources of noise such as relay wires�
Note: The black and red wires from the MPD are not used with the
XNX mV personality board. Ensure that they are properly isolated
from live connections. Do NOT cut the wires.
Caution: Do not force the POD into the enclosure. Doing so may
result in damage to the wiring or the POD or may alter the switch
settings. If resistance is felt, wires may be preventing the POD from
being properly positioned.
Caution:
Be certain to dress the wires properly to ensure cabling
does not contact switches 1-2 on the back of the POD.
