not cut or remove the grounding prong or use 2-wire extension cords or adapters to defeat
this safety feature of the product.
Do not allow anything to rest on the power cord. Do not locate this product where the
cord will be abused by persons walking on it.
Do not overload wall outlets and extension cords as this can result in the risk of fire or
electric shock.
Never push objects of any kind into this product through cabinet slots as they may touch
dangerous voltage points or short out parts that could result in a risk of fire or electric
shock.
Never spill liquids of any kind on the product.
To reduce the risk of electric shock, do not disassemble this product. There are no user
serviceable parts inside. Incorrect reassembly can cause electric shock when the unit is
subsequently used.
Unplug this product from the wall, remove the cords from the modular jacks in the unit,
and refer servicing to qualified personnel under the following conditions:
—
—
—
—
—
—
When the power cord or plug is damaged or frayed.
If liquid has been spilled into the product.
If the product has been exposed to rain or water.
If the product does not operate normally by following the operating instructions.
Adjust only those controls that are covered by the operating instructions because
improper adjustment of other controls may result in damage and will often require
extensive work by a qualified technician to restore the product to normal operation.
If the product has been dropped or the cabinet has been damaged.
If the product exhibits a distinct change in performance.
Avoid using the product during an electrical storm. There may be a remote risk of electric
shock from lightning.
If you suspect a gas leak, report it immediately, but use a telephone away from the area in
question. The telephone’s electrical contacts could generate a tiny spark. While unlikely,
it is possible that this spark could ignite a heavy concentration of gas. This product is not
approved for use in areas labeled by the Occupational Safety and Health Administration
(OSHA) as "explosive environments." Only "Explosive Atmosphere Telephones" may be
used in such hazardous environments.

1-2 Introduction

PRINCIPLES OF OPERATION
The MERLIN PFC Telephone consists of two modules: a voice module and a facsimile module, each
operating separately from the other. Two ports on the communication system controller are required for
the MERLIN PFC Telephone, two "wire runs" are needed (one for voice and one for facsimile), and
there are two jacks provided on the telephone. The voice jack on the MERLIN PFC Telephone is
labeled Voice Line and requires an analog (ATL) or hybrid port connection. The facsimile jack on the
telephone is labeled
Line and also requires an analog (ATL) or hybrid port connection.
The voice module is identical in operation and administration to a BIS-34D display telephone.

The MERLIN PFC facsimile panel has four indicator lights and three buttons (see Figure 1-1). All four
lights are controlled by the facsimile module. The Stop and Copy buttons are connected to the
facsimile module and control its operation. The Start button is not connected to the facsimile module
but is connected to a button of the voice module (the fourth button from the bottom on the right). This
button is called FAX on the voice module’s button label sheet. Pressing the
Start button is the same as
pressing the FAX button on the telephone and the two can be used interchangeably. A block diagram of
these two modules is in Figure 1-2.

To send a facsimile the following sequence of operations must occur:
●
Insert the original document in the document feeder, face down.
●
Dial a call to a facsimile machine using the voice module.
●
Transfer the call to the facsimile station, using the transfer function of your communication system.
This can be done using the one touch transfer feature, or pressing
Transfer followed by a station or
intercom button, or
Transfer followed by dialing the facsimile station/intercom number.
The facsimile station will now be rung, and the facsimile module will automatically answer. No ring
will be heard. The facsimile module, sensing an original document in the document feeder, will
enter transmission mode to send the facsimile.
To receive a facsimile automatically:
The document feeder must be empty.
●
●
The call must be dialed directly to the facsimile station or routed by an attendant to that station.
The facsimile station will now be rung, and the facsimile module will automatically answer (as
above). No ring will be heard. The facsimile module, sensing an empty document feeder, will enter
reception mode to receive and print the facsimile.
1-4 Introduction

To receive a facsimile manually:
●
The document feeder must be empty.
●
Answer an incoming call using the voice module. If it is a facsimile call then you will hear the
facsimile tones.
●
Transfer the call to the facsimile station, using the transfer function of your communication system
(as above).
The facsimile station will now be rung, and the facsimile module will automatically answer (as
above). No ring will be heard. The facsimile module, sensing an empty document feeder, will enter
reception mode to receive and print the facsimile.
The purpose of the Start button is to simplify the transfer of a call to the facsimile station. This button
will be programmed as an Intercom Auto-Dial, One Touch Transfer, or Direct Station Select (DSS)
depending on the communications system type. The following table summarizes the operation of the
MERLIN PFC and

2. Installing the MERLIN PFC
Before installing the MERLIN PFC, be sure to review the pre-installation requirements.
Pre-Installation Requirements
WARNING:
Before installing this product, be sure there is a properly grounded
3-prong AC outlet available for the MERLIN PFC power connector. Improper
grounding can result in a serious safety hazard.
WARNING:
The telephone wiring between the communications system controller
or control unit and the MERLIN PFC telephone must be installed in the same
building.
The following pre-installation requirements apply to the MERLIN PFC:
Be sure two analog (ATL) telephone jacks are available from the control unit: one for the
voice station and one for the fax station.
NOTE:
If two analog (ATL) extensions are not available, see the system manager or
●
●
●
●
administrator of the communications system.
Do not wall mount the unit due to the size and operation of the MERLIN PFC.
This MERLIN PFC telephone must be installed in the same building as the
communications system wiring and control unit or system controller. It cannot be used
with an In Range Out of Building (IROB) adjunct.
Verify that the dip switches (located on the bottom of the MERLIN PFC telephone unit)
are set to the factory default as illustrated in Figure 2-1. For more information about the
dip switches, refer to "Appendix A. Dip Switch Settings" at the back of this manual.

3. Administering the MERLIN PFC
This section contains the information to administer an AT&T Communications System for the
MERLIN PFC telephone. Before administering any communications system, read the overview
information below for background about the MERLIN PFC.
Overview
●
●
●
●
●
●
●
●
●
●
●
The MERLIN PFC consists of two basic components:
a BIS-34D telephone
a facsimile machine
The MERLIN PFC operates the same as a BIS-34D telephone set with the addition of a basic
fax machine that can send and receive faxes. The MERLIN PFC fax component does not have
any programmable fax options (for example, time/date stamp, header information, etc.). The
MERLIN PFC is designed to provide easy-to-use telephone, fax, and personal copier functions
right at the user’s desk.
To administer the MERLIN PFC for operation with an AT&T Communications System, refer
to the appropriate section within this chapter:
