Field Wiring
TX/RX Data
Terminal block 1 (TB1) on the rear panel 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 7 for terminal block location.
Power
The access panel is supplied with a modular power cord. Loosen the power connector lock on the rear of
the access panel. Plug the power cord into the connector and retighten the power connector lock. Plug
the other end into a grounded ac electrical outlet (120/230 V ac). Refer to Figure 7 for power cable
location.
N
OTE: 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 display will read “No
communication with ADVANCE” until data communication is established with the ADVANCE control
cabinet.
Audio In
Terminal block 2 (TB2) on the rear panel allows an external audio source to be connected to the panel.
Connect the audio source using a shielded twisted pair cable (No. 18–24 AWG).
The audio is summed with the handset microphone and can be broadcast to the system party line when the
hookswitch is activated. For broadcast to the system paging speakers, the hookswitch and page switch
must be activated. Refer to Figure 7 for terminal block location.
Remote Speaker
Terminal block 2 (TB2) on the rear panel allows an external speaker to be connected to the access panel.
Connect the speaker using a twisted pair cable (No. 18–22 AWG)
The speaker will broadcast the same audio as the front panel speaker but will not be affected by the front
panel volume control. Refer to Figure 7 for terminal block location.

LED Driver Outputs
The DB-25 connector on the rear panel provides 24 LED driver outputs for powering external indicators,
mechanical relays, etc. These drivers are in parallel with the front panel LED indicators on the keypad
switch. Therefore, when the front panel LED is on, the corresponding output pin is on. The pin out of the
connector correlates to the LED number, e.g. pin 1 is for LED 1, pin 2 is LED 2, etc. Pin 25 is +5 V dc to
power the remote indicators or relays.

Contact Closure Inputs
The DB-9 connector on the rear panel allows external switches to be
connected for access to the page switch, hookswitch and three
programmable inputs. The page and hookswitch inputs are wired in parallel
to the page switch contacts (on the handset) and hookswitch contacts (in the
handset cradle). Inputs 1–3 are wired in parallel to push buttons 26, 27 and
28 on the front panel.
