Installing the Management Unit
To install the Management Unit, refer to the separate instructions provided in TECP-90-805,
provided with the unit or via the QR code on the panel. The management unit contains the panel
controller and memory used to store system settings.

Connecting the Ethernet Cable and AUX Power Cable
Caution:
When connecting the equipment to the power sources, check the equipment nameplate
rating to avoid overloading circuits which may cause damage to over-current protection devices
and supply wiring
.
Each panel controller has two potential power sources. One is a Power over Ethernet (PoE)
source, and the second is AUX power from an external source.
A RJ-45 connection to the panel is required to interface the Ethernet to the end user. Connect an
Ethernet cable to the RJ-45 port. If this connection originates at a PoE switch the panel is powered
over the Ethernet connection.
If only a PoE connection is made to the panel, the PoE connection powers the panel and the AUX
power connection is not required. If both a PoE switch and an AUX power source connection is
made, the AUX power connection powers the controller. If a standard Ethernet (non PoE)
connection is made to the controller, the AUX power connection is required to power the
controller.
A PoE switch and an AUX power supply can simultaneously be connected. A PoE switch is
designed to shut power off when the presence of another power source (AUX power) is present.
If power is not provided through the AUX port, the controller assumes a PoE switch is the
voltage source. During the AUX power application to the controller, the transition from PoE to
AUX is seamless.
If AUX power is discontinued, there is an interruption of power and communications to the
controller before power is supplied by the PoE switch. Refer to Management Unit Instructions
(TECP-90-806) for AUX power details.
3.8
Connecting the Control Cable
Connect the wiring to the Ethernet RJ45 jack on the PoE switch. Plug the other end of the
Ethernet cable into the controller at the front of the panel.
The Ethernet port supports a maximum cable length of 328 feet (100 meters) to a switch. Pins 1,
2, 3, and 6 (See
) are used in 10BASE-T (10Mb/s) and 100BASE-TX (100Mb/s)
networking. Set PoE switch to auto-negotiate, the controller Ethernet port supports 10/100Mb/s.
