1. PRODUCT OVERVIEW
Nexus is a wireless call system designed for various applications including nurse and emergency call,
assisted living, elderly care homes, rapid deploy for hospitals, and bathroom alarms. The system
integrates 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.
A tablet allows up to three calls to be displayed at a time, with higher priority calls automatically moved
to the top of the alarm display. Priority levels include Call (lowest), Bath/Bed/Door, Emergency, and Code
Blue (highest). If more than three calls happen to be active at the same time, the three highest priority
events will be shown; and lower priority calls will display as events are reset, or can be seen by scrolling
down the alarm 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.
Nexus is supervised for lost connections, fault or battery low; and a software watchdog will restart the
application in the event of a system crash. A junction controller box goes even further and includes a
hardware watchdog as the ultimate safety feature (available for Nexus 2.3.0 and higher).
Messaging options include remote monitor displays large or small, mobile phones and pagers.

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 a paging transmitter, where messages can be displayed on Remote displays, pagers or
Android phones.
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.

NEXUS CALL SYSTEM by Rondish
P11
1.2.1 Receiver Dongle & Over-Door Lights
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 configured as basicsignal repeaters to extend
system coverage. The ILB-21 communicates with a Receiver Dongle (DON-30) plugged into a 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 can trigger a range by touching a magnetic key to the
program point –this reduces the signal by 3bB to ensure the connection is secure. 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.

1.2.2 Master & Network Repeaters
Medium to Large systems can be set up using a Master and Network Repeater (ZP-01(M) and ZP-01(S))
configuration. Each repeater has a range in excess of one mile in open space, and repeaters can be
programmed to “hop” through other repeater units, allowing multiple floors or a campus of buildings to
be covered.
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.

1.3 Site Testing
Conducting a site survey can help you determine how many signal repeaters are needed for your facility,
and ideal locations for them to be installed. Two pieces of equipment are available from Rondish for
measuring effective range on site.
Due to the long-distance signaling between ZP-01(S) to ZP-01(M), and ability to hop between repeater
units, the main limitation on a site survey is the distance from the call points and sensory devices to the
nearest ZP-01(S).
For this we offer NGM-21T handheld testers with a range equivalent to -3dBm, as is recommended by UL
guidance. To perform a survey, use the tester to receive and alarms and reset at the locations you propose
to install the ZP-01(S) repeater units and test at the extremes of that particular zone. If your calling device
can be received by the tester at the proposed install location, you can be confident that it will reliably
work when a more sensitive ZP-01(S) is used for the actual installation.
For smaller facilities the ILB-21 Over-Door Lights can serve as the repeaters –the TTEST-01 can be used
for surveying these sites if necessary.

1.3.2 Pre-Install Survey
Rondish recommends using floor plans to propose locations for ZP-01(S) signal repeaters in corridors at
regular intervals, around 40-50m apart. For a multi-story building operating as a single system, you can
offset the positions of repeaters on different floors (if you don’t care about locating mobile alarms). The
distances achievable will depend vary according to the structure of the building, with steel and concrete
much lower than wood and drywall.
Once you have proposed installation positions for the ZP-01(S) repeater units, you can visit the site with
your map and test out a few of the locations with the Pegasus range tester.
Place a WCP-11 at the furthest distances from the proposed ZP-01(S) location and test the Pegasus can
receive the signal. If the Pegasus tester will receive alarm and reset signals you can be confident about
the signal reliability into a ZP-01(S) repeater. In particular check the locations in the corners and make
sure the nearest ZP-01(S) is well within range. Pay particular attention when going through multiple
walls.
If TXP-11 are being used on this site, repeat using this device at the furthest distance it will be used, and/or
where there are obstacles blocking the path.
Note:

NEXUS CALL SYSTEM by Rondish
P15
If using a Receiver Dongle & ILB-21 Over-Door Lights, use the TTEST-01 instead of an NGM-21T
•Use TTEST-01 where you propose to place the ILB-21
•Use the TXP-11 to test for itself or the NGM-21
•Use the WCP-11 for its range
•Use the head set to listen for any noise on the site
1.3.3 Installation
Based on the site survey you should have a good idea if your original ZP-01(S) positioning will cover the
area and can start the installation.
Place each ZP-01(S) at the proposed locations and then power up the repeaters. When the Nexus is
launched, it will attempt to establish the repeater network, linking to each ZP-01(S) in turn. Make sure
each ZP-01(S) is programmed correctly using the same Network ID, Frequency Channel, and each has a
unique address (See Section 2.2).
When the link is established, a Relative Signal Strength Indication (RSSI) value will be recorded in the
Nexus Event Log, which will be a number between 0-255. An RSSI value of 80 or above is OK, however
Rondish recommends that readings below 100 be programmed to hop through a ZP-01(S) with a higher
RSSI reading for the most reliable performance. You are allowed to hop through 2 x ZP-01(S) units (3
hops).
Once the network is optimized you can start to install call points or other alarm devices throughout the
building. The main thing to ensure is that the units have different ID codes and that the site code is set
correctly, if applicable.
Once the WCP-11 is installed in the position required you can do a range safety check using the magnet
keychain device (or any magnet) to send a signal ~ -3dB to trigger the system. This is done by placing a
magnetic key on the reset button and pressing the call button.
The TXP-11 units should be tested at the extremes of the area to ensure they can be received and detailed
records of the tests kept.
Note:
If using a Receiver Dongle & ILB-21 Over-Door Lights, you can test the network by touching a magnet to
the blue dot on the ILB-21 to reduce the signal transmission by -3dB. This will confirm the signal strength
between ILB-21 & DON-30 is sufficiently strong.
In the event you cannot reach the Nexus main station you will need to add a Range extender or reposition
the position of the ILB-21 units.
Finally check all the call points are working correctly.

NEXUS CALL SYSTEM by Rondish
P16
1.3.4 Full System Test
Test all call points throughout the building. You can check the RSSI reading on the computer to see if any
readings are low to give a guide, especially the pendant TXP-11 units. Keep a record of all test results for
future reference.
Test all units for call and reset.
It is important to be methodical in this testing and keep good records so it is recommended
to make a matrix of test results to ensure all units are tested and in good order. Check all the worst-case
positions to ensure calls can be received.
The test procedures are similar to the ZP-01(S) except the range to an ILB-21 Over-Door light is more
limited, requiring a different range tester must be used. This is achieved but using the TTEST-01 unit
above.

2. INSTALLATION
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 NDP-21/TVB-21 and connect the DON-30 Receiver Dongle or ZP-01(M) Master
Controller –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 your organization (optional) in the Settings menu. If a DON-
30, 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 ZP-01(M) Master
Controller –Refer to section 2.2 for details. 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. Add and mount call points (Section 2.3) and sensors in Device Management 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

2.1 Master Station
Start your installation by powering up the device you will use for the Master Station. There are two
current hardware options:
2.1.1 Station Hardware
Nexus can operate on a Rugged Tablet (NDP-21) for an easily configurable desktop solution, or on a
versatile Control Box (TVB-21) that allows a monitor or any size to be connected. A System Controller
(NCON-11) includes a Control Box, Paging Transmitter, USB hub and failsafe circuitry in one housing, and
will allow the user to interface with Nexus using a touch screen or wireless keyboard & mouse.
Nexus Rugged Tablet (NDP-21)
The Rugged Tablet comes with a docking station that allows convenient placements on a nurse desk. The
back of the docking station includes three USB connections, allowing a DON-30 or ZP-01(M) to connect a
network, and a GP2009TR paging transmitter to signal paging signals. The ethernet port allows for a LAN
and central database of multiple Nexus stations.

Nexus Junction Box (NCON-11)
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). It includes a TVB-21 to run Nexus –which
can be connected to computer monitors of various sizes through an HDMI cable –and a GP2009TR
transmitter for messaging.
The NCON-11 includes power handling (surge suppression, fuses, regulators) with outputs for the various
items, AC lost and battery low detection, and a hardware watchdog to reset the system in the unlikely
event of a system crash. For Master Station we recommend a touchscreen for ease of use, although a
Bluetooth mouse or keyboard can also be used.
