NetAXS™ NX4L1 Installation Installation The Power Distribution Output board has two dry contact outputs that can be used to monitor the general condition of the system. The TRBL relay output is de-energized if the +24 VDC is off or if a PTC is active. The FACP relay output will de-energize if the external FACP input is active. Either one of these outputs can be optionally wired into the supervised inputs on the NetAXS panel and configured as two-state inputs. The following figure shows the power distribution board field wiring. Power Distribution Board Field Wiring Figure 9: Power Distribution Board Field Wiring 20 www.honeywell.com

NetAXS™ NX4L1 Installation
Installation
The Power Distribution Output board has two dry contact outputs that can be used to monitor the
general condition of the system. The TRBL relay output is de-energized if the +24 VDC is off or if a
PTC is active. The FACP relay output will de-energize if the external FACP input is active. Either one
of these outputs can be optionally wired into the supervised inputs on the NetAXS panel and
configured as two-state inputs.
