NEXUS CALL SYSTEM by Rondish

1. PRODUCT OVERVIEW

Nexus is a wireless call system designed for many applications including nurse and emergency call

applications, assisted living, elderly care homes, fast deploy systems, disabled bathroom alarms and other

applications. The system offers integrated emergency alarm call, wander prevention, bed alarms for fall

management, and mobile calling devices for residents to wear on their wrist or around the neck.

The system is supervised for lost connections, fault or battery low; and the main Nexus system includes a

software watchdog to restart the main program in the unlikely event of a system crash. A junction

controller box goes even further and includes a hardware watchdog as the ultimate safety feature.

Up to three calls can be displayed at a time, with higher priority calls automatically moved to the top of

the alarm display. Alarm priority levels are Emergency, Bath/Bed/Door, and standard Call. If more than

three calls happen to be active at the same time, the three highest priority events will be shown, and

lower priority/newer calls will display as the higher priority/older events are reset or can be shown by

scrolling down the screen. All events are logged with a record of event location, call type, time of trigger

and duration.

Optional Over-door lights show Call, Bath or Emergency status. Each light has an internal buzzer with

adjustable volume, and can repeat the signal to greatly extend range and improve the reliability of

wireless coverage. These can battery power, DC powered or both.

Several messaging options are available, including remote monitor displays large or small, mobile phones,

pagers and LED displays. These can work through a paging transmitter, the existing WiFi network, or a

dedicated mesh WiFi installed for this purpose.

1.2System Layout Options

Nexus uses a proprietary wireless format to direct signals from call points and sensory devices to a nurse

station, where calls are displayed on the main Nexus panel. Once received, this panel can direct messaging

to staff using either a paging transmitter or a local WiFi network, where messages can be displayed on

Remote displays, pagers or Android phones. Note: The local WiFi can be a network already installed in

the building or a dedicated mesh separate network installed.

Several receiving options are available to cover buildings of various sizes. Signals are brought into the

Android device using a Receiver Dongle (DON-30) for smaller areas, or Master Controller and Network

Repeaters (ZP-01(S)), which relay the call points and sensory devices status. When using Network

Repeaters, signals can be “hopped” from one repeater to another to further extend the wireless coverage.

The following layout diagrams give an overview to the options available depending on the complexity and

size of the building and type of equipment required.

P10

1.2.1 Receiver Dongle & Over-Door Lights

Rondish Over-door lights (ILB-21) receive local signals from a variety of calling units, and can either be

configured as lights/sounder by reading into memory the calling unit, or set up to just extend the system

coverage without any local alarm. The ILB-21 uses bi-directional communication with a Receiver Dongle

(DON-30) plugged into the Rugged Tablet (NDP-21), Nexus Control Box (TVB-21), or Nexus Junction Box

(NCON-11).

When used as a range extender the ILB-21 transmitter uses LoRa on a separate 400MHz channel to the

calling device. When connecting the ILB-21 you should check the range using the programing magnetic

key as this reduces the signal by 3bB to ensure the normal connection is secure (see the ILB-21 installation

instructions). The open-air ranges of the devices are shown on the diagram below.

The ILB-21 can be battery operated with a standby life of 18 months –ideal for a fast deploy or bathroom

alarms –or powered from a 12V supply with batteries used as backup.

P11

1.2.2 Master & Network Repeaters

Medium to Large systems can be set up using a Master (ZP-01(M)) and Network Repeater (ZP-01(S))

configuration. The advantage of this system over LoRa is higher speed and larger RF coverage. This allows

for a network to be put together inside the building and the system networked using hops if required to

extend the range.

Example: Multi-floor building

Up to 3 hops can be used on the

system, and using the RSSI readings

viewable through the Event log on

Nexus this can be optimized for the

best layout.

There may be a bit of trial and error

to achieve the best RSSI levels by

changing the target address and

seeing if the RSSI level is higher or

lower.

You will be able to cover large areas

and multi-floor buildings using this

method to configure the system.

1.2.3 Messaging through Paging Transmitter

The Nexus display panel can be programmed to send signals to the pagers/displays using POCSAG codes

(Refer to GP2009TR UI for details of configuring transmitters and setting capcodes). The paging

transmitter can be connected to the USB port on the NDP-21 docking station (See Section 2.1.1), allowing

messaging to pagers or LED display panels. This has a range up to several Km/miles and can send a signal

to a pager or a wireless LED display as shown.

This setup is applicable where the local WiFi is unavailable but the user prefers a mobile phone and

computer based remote displays. In this case the remote displays can be Tablets or Android based

displays with a paging receiving dongle. The mobile phone app (Samsung phone recommended) can be

added providing the Nexus console is connected to the internet and uses the cloud and local GSM

network.

1.2.4 Messaging through WiFi

Presently under development is a WiFi based option of the system for both the remote displays and the

mobile phone using the internal LAN or mesh network. The WiFi network can be either use a system that

is already installed or can be easy installed using a Mesh WiFi system.

NEXUS CALL SYSTEM by Rondish

P14

1.2.5 Nexus Junction Box

This is based on the mini android computer which can be connected to various monitors of different sizes.

The Nexus Junction Box (NCON-11) has been designed as a control box so that you can simply plug into

the box the items that you require including DON-30, ZP-01(M), Paging transmitter, touch screen monitor.

In addition, Rondish will soon have a local point to point WiFi link to an NDP-21, which will allow the NDP-

21 to be placed freely within a room and the NCON-11 placed outside in the corridor, thereby increasing

the coverage and making the system very flexible.

The NCON-11 includes various features such as power handling (surge suppression, fuses, regulators) with

outputs for the various items, AC lost and battery low detection, and includes a hardware watchdog to

reset the system in the unlikely event of a system crash. For main Nexus monitor we recommend a

touchscreen for ease of use, although a Bluetooth mouse or keyboard can also be used.

1.3 General Operation

Nexus follows general accepted principles of a nurse call system as described in the UL and HTM-08

standards. Patient calls should be reset at location by the nurse or caregiver as soon as can reasonably

be achieved.

1.3.2 Network Repeater Status

The ZP-01(S) is a critical part of Nexus operation, as it is the link between the wireless calling devices and

the Master controller, then to Nexus. If you think this is not working properly, the LED can give an

indication of the current status.

NEXUS CALL SYSTEM by Rondish

P16

Dongle Indications

Green LED steady, Red LED flashing –Repeater cannot connect with the master

Green flashing LED –Repeater successfully connected with the master

Red flashing LED –Repeater receiving data

An error message will display if the Receiver Dongle or Master Controller ZP-01(M) is removed or loses

connection while Nexus is active. Your system cannot function without this receiver connected, so Nexus

will prompt you to resolve this before any further action can be taken.

1.3.3 Lost Device Detection

Nexus will display any faults that are detected within the local network. Warnings display according to

the schedule below:

Call devices –24hrs

Signal repeaters –10mins

2. INSTALLING NEXUS

Nexus is designed for a straightforward installation process that minimizes your time spent on site.

Following these steps will have your system up and running in just a few hours:

1. Switch on the tablet/TV Box and connect the receiver dongle DON-30 or Master Controller ZP-

01(M) –the application will automatically open to a splash screen displaying the version of Nexus

installed on this device

2. Change the PIN and enter name of organization (optional) in the Settings menu. If a receiver

dongle DON-30 is used, skip to Step 5. If repeaters are used you must configure the Network ID

and Channel.

3. Program ZP-01(S) repeaters to use the same Network and Channel selected at Master Controller

ZP-01(M). When all Repeaters in the network are initialized by the Master, power up or

connection, check the RSSI values shown in the Event Log. Rondish recommends programming a

signal hop if recorded RSSI values are below 100

4. Pair call points and sensors with Nexus and define how each should display during a call –refer to

Section 3.3 for details of adding and renaming devices.

5. Pair call points and sensors with over-door lights (optional)

6. Mount over-door lights (if used), call buttons and brackets for patient handsets

7. Test all of the call points three times (call & reset) to ensure that signals are reliably received by

the Nexus
