Care Centre Installation Requirements

 

In order to avoid any confusion or misinterpretation the following document has been drawn up.  The primary objective of the document is to establish standards that all BeSecure Frail-Care installations comply with. 

Standards allow for quicker installation time and faster fast turnaround on fault finding.  BeSecure will sign off all completed installations based on the standards listed in this document. 

 Tools Required 

  1. Ladder

  2. Brother label machine or similar

  3. Extension cord

  4. Masonry drill and bits

    • 6mm masonry drill bit

    • 4 mm plastic drill bits

  5. 20mm hole saw

  6. Flat and Phillips screw driver

  7. Terminal screw driver (<2mm flat blade)

  8. Wire strippers

  9. Ferrules & crimper

  10. Heat shrink (6mm, 4mm & 2mm)

  11. Heat gun

  12. Cable markers

  13. 4 x 12mm nut and bolts

  14. Fisher 6mm masonry wall screw

  15. 24mm & 26mm sockets or spanners (for the IP66 glands)

  16. Pencil & tape measure

  17. BeSecure Sniffer

  18. Laptop with the BeSecure Utilities installed

Standard installation Practice 

The following are installation best practices that need to be followed. 

  1. All devices are mounted at right angles using a spirit level  

  2. All installed cables must be labelled at both sides of the cable 

  3. When installed in false ceilings, BeSecure hardware must be installed in a hinged IP66 housing.

Wiring Requirements 

  1. Only specified cable or a direct replacement from an alternative vendor must be used.

  2. All cable ends must have the following:

    1. Heat shrink

    2. Ferrules

    3. Cable markers as per the assigned number for that cable

    4. All unused cable must be cut away

Where multiple cable cores are used for a single connection the cables must be twisted together with a ferrule connecting both at the end. 

Bed numbering 

Ward bed numbering is standardized.  The numbering model is as follows: 

  • While standing at the ward main door the first bed on your right is number 1

  • The second bed on the right is number 2

  • This continues until all the bed on the right are numbers

  • The furthest bed on the left is the next number, counting up as you come back to the main door. 

The images below give examples of the various bed layouts and the associated numbering. 

The full unique number allocated to the bed will be the Ward number first then a dash and then the bed number.  For example, bed number 2 in ward 1 will be 01-02; Bed number 4 in ward 8 will be 08-04. 

All Bedside Units (BHI1003-051-01) must be labelled internally (label on the lid and the base) with this labelling format.

The bed numbering corresponds with the ports on the Ward Controller. The table below provides the format that must be followed. The pattern shown is then followed out to additional rooms.

Ward Controllers Architecture

Each ward will have a Ward Controller installed above the main entrance to that ward.  The following installation requirements apply: 

  1. The Ward Controller (BHI1003-050-01) will communicate with the BeSecure Repeaters via the BeSecure 868Mhz Wireless network. 

  2. The Ward Controller can support a maximum of 4 Bedside bell-press units (BHI1003-051-01) 

  3. The maximum distance from the Ward Controller to the Bedside Unit must not exceed 50m 

  4. The Ward Controller must be powered locally using the supplied power supply unit.

  5. The Bedside Units are powered from the Ward Controller. 

  6. The Beside Units must be connected to the Port number allocated to that respective bed. The numbering chart can be reviewed in the Bed Numbering section of this page.s labelling format.

RS485 Architecture

Frail care installations are completed with RS485 Repeaters.  As per the system architecture below the following installation requirements apply: 

  1. The RS485 cable must be installed as a daisy chain connection

  2. The maximum distance from the Controller to the final Repeater must not exceed 500m 

  3. The total number of Repeaters on a single RS485 bus must not exceed 7 

  4. The Controller and Repeaters must be powered at their installed location using the supplied Power Supply Unit (PSU)

  5. All BeSecure Repeaters and Controller must be installed in IP66 housing if installed in the false ceiling or cupboard.

Installation Notes

All BeSecure Repeaters and Controller in the field must be installed in the same way.  This will reduce support efforts in tracing and establishing faults in the unlikely event that they arise. 

When establishing a location of the hardware the following considerations should be taken into account: 

  1. The BeSecure Controller or Repeater is easily accessible.

    1. Ideally without a ladder however If a ladder is necessary the unit must be close to a roof access point.

    2. The mounting point should consider the need to place a laptop next to the housing when period firmware upgrades need to be made.

  2. Enough cable slack must be allowed to ensure that the cables are not under tension and there is some give in the housing should items need to be moved around.

Enclosure Installation Guidelines

Install the two metal glands

  1. 20mm from the lip

    1. 50mm in from each side

    2. Left gland is a 00

    3. Right gland is 01

  2. The wiring is as follows:

    1. Left (Gland size 00)– PSU and comms from Controller

    2. Right (Gland size 01) – Antenna and comms to next Repeater

Enclosure Installation

Wiring Guidelines

  1. Push the wire from the Controller through the left gland

  2. Push the wire from the next Repeater through the right gland

  3. Strip back the sheath 80mm

  4. Twist the wires together and strip the ends

  5. Locate a ferrule on each

  6. Cover with heat shrink and shrinkund.

Wiring Steps

Preparing the Peripheral Enclosure

Mount the BeSecure base onto the IP66 housing base

  1. The top of the base should be 5mm below the backing plate line

  2. Drill a 4mm hole in the top right and left corners of the base and through the mounting plate

  3. Insert the PSU and comms cables into the base cabling holes and insert the gland clips.

  4. Fasten the base to the mounting plate.

  5. Insert the antenna cable through the right gland

Peripheral Enclosure Mounting

Connecting the Peripheral PCB

Connect the Repeater PCB

  1. Insert the PCB and connect the PSU

  2. Wire up the RS485 Communications

    • A = Yellow

    • B = Green

    • Gnd = Blue

  3. Connect the rubber grommet and Antenna on the top connector

Connecting the Peripheral PCB

Mounting the Peripheral into the main enclosure housing

Insert the mounting plate into the housing

  1. Print and mount required labels to the mounting plate (not shown in this image)

  2. Locate the mounting plate

  3. Fasten all 4 mounting points of the mounting plate

  4. Neaten cables

Mounted Repeater

Powering up the Equipment

Power up and commission

  1. Once all hardware has been installed

    1. Ensure the serial number is programmed in the software

    2. Upload the modified Config file

    3. Bring up each Repeater (Mains power and battery connected) and watch on the sniffer to ensure that the communications are as to be expected.

    4. Close up the BeSecure lid

    5. Close up the IP66 lid

  2. Ensure that the label for that Repeater is visible on the lid of the housing (not shown here)
