Introduction

This section describes the procedures you should follow to plan and prepare a site for an Avalon
FM40/FM50 fetal monitor installation.

• Site planning.

• Roles and responsibilities for local and Philips personnel.

Site Planning

The careful planning of the site for the FM40/FM50 monitor is essential for its safe and efficient
operation. A consulting schedule should be established between the Customer and Philips Sales and
Support Representatives, to ensure that all preparations are completed when the system is delivered.

2

2Site Preparation

The site planning phases prior to equipment installation are:

Location: Planning the location of the various system components.

Environment: Confirming and correcting, as necessary, the environment of the proposed installation

site(s).

System Capabilities: Explaining the possibilities for system expansion.

Mounting: Referencing the mounting hardware information website for the listing of suitable

mounting hardware recommended for use with the various system components, and all details on the
available mounts and accessories.

Cabling: Identifying the requirements for the cabling, conduiting and faceplates for connecting the
various system components.

Roles and Responsibilities

This section describes the procedures necessary to prepare a site for a system installation. The
procedures are grouped into two parts: procedures that local staff or contractors are responsible for, and
procedures that Philips personnel are responsible for.

Site Preparation Responsibilities

Local Staff

• Ensure that all safety, environmental and power requirements are met.

• Provide power outlets.

• Prepare mounts, and consult Philips for detailed mounting requirements.

5

2 Site Preparation Introduction

• Pull cables, install conduit, install wallboxes.

Philips Personnel

• Provide the customer with the safety, environmental and power requirements.

•Assemble mounts, as necessary.

• Provide requirements for cabling.

Procedures for Local Staff

The following tasks must be completed before the procedures for Philips personnel may be started.

• Providing Power Outlets

Provide a power outlet in the vicinity (1 m or 3 ft) or any peripheral equipment.

WARNING Only the power cables provided with the system may be used. For reasons of safety, power (mains)

extension cables or adapters shall not be used.

• Preparing Mounts

Where ceiling, wall, or shelf mounts are required for mounting the equipment, the customer is
responsible for the following:

– Providing and installing all hardware which is required to install the mounting hardware supplied

by Philips as detailed in the installation notes.

– Making sure that all ceilings, walls, and mounting rails that supports mounting hardware are

suitable for their proposed load.

WARNING It is the customer's responsibility to have the attachment of the mounting hardware to the ceiling, wall,

or mounting rail and the construction of the ceiling, wall, or mounting rail evaluated for structural
integrity and compliance with all local, state and any other required codes by a registered, professional,
structural and/or mechanical engineer.

Although considerable effort has been made to ensure the safety of the ceiling mount installation and
or mounting guidelines, it is to be understood that the installation itself is beyond the control of Philips
Medical Systems. Accordingly, Philips Medical Systems will not be responsible for the failure of any
such installation.

• Providing Conduit

– Providing conduit and/or trunking of a sufficient cross-sectional area for the planned cables and

possible future expansion (for additional components or systems).

– Providing and/or installing suitable wall boxes to accommodate the faceplates.

•Pulling Cables

WARNING NEVER run power cables through the same conduit or trunking used for system cables.

•Installing Wall Boxes

6

Site Requirements 2 Site Preparation

It is the customer's responsibility to provide and install wallboxes to house faceplates. The customer
must notify the Philips installation coordinator of which size is to be used.

Procedures for Philips Personnel

Before you begin the procedures in the installation sections, ensure that the customer has completed all
necessary preparations outlined in the previous section, “Procedures for Local Staff.”

Site Requirements

The site requirements are listed in this section.

Space Requirements

The situating of the monitor should be planned such that the nursing staff are able to monitor the
patient with relative ease, with all patient connectors and controls readily available and the displays
clearly visible. The location should also allow access to service personnel without excessive disruption
and should have sufficient clearance all round to allow air circulation.

Safety Requirements (Customer or Philips)

The monitor is an electrical Class I device in which protection against electric shock does not rely on
basic insulation only, but which includes an additional safety precaution, in that means are provided
for the connection of the equipment to a protective earth conductor in the fixed wiring installation in
such a way that accessible metal parts cannot become live in the event of a failure of the basic
insulation.

WARNING • Always use the supplied power cord with the earthed mains plug to connect the monitor to an

earthed AC mains socket. Never adapt the mains plug from the power supply to fit an unearthed AC
mains socket.

• Do not use additional AC mains extension cords or multiple portable socket-outlets. If a multiple
portable socket-outlet without an approved separating transformer is used, the interruption of its
protective earthing may result in equipment leakage currents equal to the sum of the individual
earth leakage currents, so exceeding allowable limits.

Electrical Requirements (Customer or Philips)

Line Voltage Connection

The FM40/FM50 monitor uses < 60 W.

Line Voltage: the FM20/FM30 monitor may be operated on ac line voltage ranges of
100 to 240V (50/60 Hz).

Connecting Non-Medical Devices

The standard IEC/EN 60601-1-1 applies to any combination of devices, where at least one is a medical
device. Therefore IEC/EN 60601-1-1 must still be met after all devices are connected.

WARNING • Do not use a device in the patient vicinity if it does not comply with IEC/EN 60601-1. The whole

installation, including devices outside of the patient vicinity, must comply with IEC/EN 60601-1-1.
Any non-medical device, including a PC running an OB TraceVue system, placed and operated in
the patient’s vicinity must be powered via a separating transformer (compliant with IEC/EN 60601­1-1) that ensures mechanical fixing of the power cords and covering of any unused power outlets.

• Do not connect any devices that are not supported as part of a system.

8

Site Requirements 2 Site Preparation

Whenever you combine equipment to form a system, for example, connecting the monitor to an OB
TraceVue system, perform a system test according to IEC/EN 60601-1-1 (see “System Test” on
page 38).

Figure 1 Equipment Location in the Patient Vicinity

Cabling Options and Requirements for Connection to OB TraceVue

For cabling options and requirements for connection to an OB TraceVue system, refer to the OB

3Installation Instructions

The information contained in this chapter, in addition to that given in the Instructions for Use, should
enable the monitor to be installed ready for use (the preparation and planning should be adhered to as
specified in the “Site Preparation” chapter). Safety checks and inspection procedures for mounts are
explained in the “Testing and Maintenance” chapter, and configuration of the system is explained in
the “Configuration” chapter.

Please keep the packing materials until you have completed the initial inspection, in case there is a
defect on arrival.

Initial Inspection

Inspect the delivery on arrival.

3

Visual Inspection

Open the shipping container(s) and examine each part of the instrument for visible damage, such as
broken connectors or controls, or scratches on the equipment surfaces. If the shipping carton/container
is undamaged, check the cushioning material and note any signs of severe stress as an indication of
rough handling in transit. This may be necessary to support claims for hidden damage that may only
become apparent during subsequent testing.

Electrical Inspection

The instrument has undergone extensive testing prior to shipment. Safety testing at installation is not
required (except in situations where devices are interconnected forming a system, see “Connecting
Non-Medical Devices” on page 8). An extensive self check may be performed. This recommendation
does not supersede local requirements.

All tests are described in the “Testing and Maintenance” chapter of this manual.

Claims for Damage

When the equipment is received, if physical damage is evident or if the monitor does not meet the
specified operational requirements of the patient safety checks or the extended self check, notify the
carrier and the nearest Philips Sales/Support Office at once. Philips will arrange for immediate repair or
replacement of the instrument without waiting for the claim settlement by the carrier.

13

3 Installation Instructions Repackaging for Shipment or Storage

Repackaging for Shipment or Storage

If the instrument is to be shipped to a Philips Sales/Support Office, securely attach a label showing the
name and address of the owner, the instrument model and serial numbers, and the repair required (or
symptoms of the fault). If available and reusable, the original Philips packaging should be used to
provide adequate protection during transit. If the original Philips packaging is not available or reusable
please contact the Philips Sales/Support Office who will provide information about adequate
packaging materials and methods.

Mounting Instructions

Every type of compatible mounting solution is delivered with a complete set of mounting hardware
and instructions. Refer to the Site prep chapter for a list of mounting options. Refer to the
documentation delivered with the mounting hardware for instructions on assembling mounts.

WARNING It is the customer's responsibility to have the attachment of the mounting hardware to the ceiling, wall,

or mounting rail and the construction of the ceiling, wall, or mounting rail evaluated for structural
integrity and compliance with all local, state and any other required codes by a registered, professional,
structural and/or mechanical engineer.

Ensure that this commitment has been met before assembling mounts.

Line Voltage Selection

You do not need to set the line voltage, as this is done automatically by the power supply. The monitor
has a wide-range power supply that allows you to operate the monitor from an AC (alternating current)
power source of 100 V to 240 V (± 10%) and 50/60 Hz (± 5%).

The monitor is an electrical Class I device in which protection against electric shock does not rely on
basic insulation only, but which includes an additional safety precaution, in that means are provided
for the connection of the equipment to a protective earth conductor in the fixed wiring installation in
such a way that accessible metal parts cannot become live in the event of a failure of the basic
insulation.

WARNING • Always use the supplied power cord with the earthed mains plug to connect the monitor to an

earthed AC mains socket. Never adapt the mains plug from the power supply to fit an unearthed AC
mains socket.

• Do not use AC mains extension cords or multiple portable socket-outlets.

Connecting the Monitor to Non-Medical Devices

Connect the monitor to an obstetrical surveillance system, such as OB TraceVue, via the optional
system interface. For cabling requirements, refer to “Cabling Options and Requirements for
Connection to OB TraceVue” on page 9. For safety-related information, refer to “Connecting Non­Medical Devices” on page 8, and “System Test” on page 38.

3 Installation Instructions Before Using the Monitor

Checking/Setting Paper Speed

Check the paper speed before using the monitor. You can choose a paper speed of 1, 2, or 3
centimeters per minute (cm/min). The default setting is 3 cm/min. In Monitoring Mode, you can see
this setting (grayed out), but you cannot change it. It can be changed in Configuration Mode.

As a change in paper speed results in a change in the appearance of a FHR trace, you are advised to
ensure ALL monitors in your institution are set to the same speed.

To set the paper speed:

1 Enter the Main Setup menu using the SmartKey .

2 Select Fetal Recorder.

3 In the Recorder menu, you can see the current speed setting. Select Recorder Speed.

4 Select the desired speed from the given choices: 1, 2 or 3 cm/min.

Power Supply

The power supply is a wide-range input switching unit, with an output of 24V. It is located in the chassis
assembly.

Fetal Sensor Connector Block

Any compatible fetal transducer can be connected in any order to the monitor via the sockets on the
Connector Block. The Connector Block is located on the Bus Master section of the All Peripheral
Interfaces (API) Board, and is exchangeable.

API (All Peripheral Interfaces) Board

The All Peripheral Interfaces (API) Board is connected to the Main CPU Board by a 154-pin 0.5 mm
pitch press fit connector.

20

The recorder is controlled by the Printer Control section of the API Board, which is connected to the
Stepper Motor and the Thermal Printer Unit.

The signals from the transducers or sensors are conveyed from the sensor sockets to the Bus Master section
of the API Board. The Telemetry Interface is also integrated into the API Board.

The Bus Master section is responsible for transducer detection, communicates with the connected
transducers via a CAN bus, and communicates parameter data to the Main CPU Board via a serial link for
further processing and display. It has floating power isolation.

The API Board also controls the display panel and the backlight converter, and also controls the
touchscreen. The display panel is connected to the API Board. The VGA connector is also connected to
the API Board.

The API Board incorporates an audio amplifier which controls the loudspeaker.
