Site Preparation

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.

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.

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 60601- 1-1) 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).

Installation 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.

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.

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%).

Power Supply

The monitor consists of the following main functional components:

•Power supply

•API (All Peripheral Interfaces) Board

•Main CPU Board

•Fetal Recorder (Thermal Printer Unit)

•Fetal Sensor Connector Block

•Noninvasive Blood Pressure Board

•SpO2 Board

•Input /Output Interface Boards:

–LAN / RS232

–Dual PS/2 (optional)

–MIB / RS232 (optional)

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.

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.
