Field Wiring
Data (TX/RX)
An eight-pin data port (RJ45 jack) on the rear of the unit connects
the access panel data line to the ADVANCE System control cabinet.
A twisted pair cable (minimum Category 3) should be used for this
connection.
Observe cable conductor polarity (+/−) when making connections at
the control cabinet: (+ connects to + and − connects to −). No
damage will occur if the polarity is reversed, but the access panel
will not function. Maximum cable distance to the control cabinet is
3 km when using No. 24 AWG (Category 3) cable.
Refer to Figure 3 for RJ45 jack pin out detail and Figure 5 for the
data port location.
: Pin 5 (+) and pin 4 (−) should be used for new installations.

the power connector on the rear of the unit. Plug the other end into an ac electrical outlet (120 V ac @
50/60 Hz). Refer to Figure 5 for power connector location.
: The access panel does not have an on/off power switch and will power up immediately upon

plugging in the power cable. The ADVANCE System control cabinet must also be powered and running
before the access panel is operational. LEDs on the access panel will flash and the sounder will "beep"
until data communication is established with the ADVANCE control cabinet.

Panels is specifically designed for this unit and must not be used with any other 12576 series or 727 series
