HMI Panel Instruction Manual
1.0 Introduction
1.1 Description
The SmartWireless™ Human Machine Interface (SW HMI) panel is a read only remote display unit
designed to operate with Detcon’s RXT-300 wireless transceivers. It consists of an SW HMI module
which provides an operator interface to an RXT-300 network and displays real time status of all configured
network devices up to a maximum of 32 devices. Devices can be sensors, alarm stations, repeaters and
other remote displays.
The SW HMI panel utilizes a non-intrusive magnetic interface operated by a small programming magnet
and displays the real time status of devices on a backlit LCD. In normal operation, the SW HMI panel
provides real time display of device number, gas concentration, device tag and the status of other field
devices like Detcon’s Smart Battery charge levels, network RF signal quality and various fault diagnostic
conditions affecting either an individual field device or the network in general. The front panel LED
indicators provide the status of a device’s three alarm levels (Alarm 1, Alarm 2 and Alarm 3) and fault.
Command functions such as alarm test and radio silence are included as well as additional features such as
alarm inhibit, alarm reset and alarm silence (acknowledge) functions.
The SW HMI module is available in a choice of two enclosures. The first enclosure type is the Model SWHMI-32-N4X which is housed in a NEMA 4X water proof enclosure and has a built in power supply that
takes in 110/220VAC and outputs 24VDC. External DC power (11.5-30VDC) can also be provided by the
customer to power the remote display if AC power is not available or desired. This unit provides DIN rails
which are used to mount the power supply and terminal blocks. The required RXT-300 wireless
transceiver and custom terminal board (8-Position) will need to be purchased separately for this enclosure
type.

The second enclosure type is the Model SW-HMI-32-N7 which is housed in a NEMA 7 explosion proof
aluminum panel enclosure. Due to this enclosure type, the unit’s internal space is limited and cannot
support a built in power supply or DIN rails. It comes preassembled with an RXT-300 wireless transceiver
and derives its power from a Smart Battery Pack enclosed in an aluminum condulet with a custom terminal
board, all installed on a custom mounting plate. The SW HMI’s advanced design takes advantage of a low

power LCD with back light and ultra low power components that extend operating time for 1-2 months
before a recharge is required. Additionally, an optional solar charging panel can be used to extend
operating time for virtually any application.

1.2 System Operation
The heart of the SW HMI is the non-intrusive magnetic interface with backlit LCD display. The display
receives real time data from RXT-300s using RS-485 Modbus™ RTU protocol. The SW HMI includes a
primary Modbus™ interface (COMM1 Master) used to receive concentration and status directly from the
RXT-300 transceiver (Slave) being monitored. A secondary Modbus™ interface (COMM2 Slave) is also
available which is used for communication with another remote display where the SW HMI is seen as a
slave device. The SW HMI panel only monitors the network and does not perform the actual polling of
sensors and processing of alarms. It only provides the user a visual status of the system including fault
conditions and managing of alarm events such as alarm inhibit/reset/silence. Wiring of an external manual
switch is also available to act as an Acknowledge/Reset button. This switch comes preinstalled for the
N4X enclosure and is optional for the N7 enclosure (See section
3.3 Optional Remote Alarm
Reset/Acknowledge Switch (N7 Enclosure)).
1.3 RXT-300 Wireless Transceiver
The wireless function of the SW HMI panel is made possible by Detcon’s RXT-300 wireless transceiver.
This transceiver transmits signal data such serial Modbus™ and can support up to 32 devices. It operates at
2.4GHz and conforms to non-licensed radio frequency appliance usage around the world. Wireless
network integrity and security is accomplished using direct sequence spread spectrum wireless mesh
technology. Wireless applications can be as simple as a single field device communicating with an SW
HMI panel or any number of field devices forming a network of subscribers. Every device in the network
is capable of functioning as a router and repeater for all other devices in the network. This means that
subscribers can “hop” through neighboring devices to communicate with each other thereby widening
network access points. This unique and innovative technology is designed to create a robust network that
automatically routes around congestion and line-of-sight obstacles while improving throughput as
subscriber device density increases. The RXT-300 also provides a network wide control processing
capability. Refer to its instruction manual for more detailed information.

1.4 Terminal Board and Smart Battery Pack (N7 Enclosure Only)
The Model SW-HMI-32-N7 panel assembly comes with a custom terminal board (5143) and smart battery
pack mounted inside an aluminum condulet. The terminal board includes connector plugs for the
following:

Figure 3 Terminal Board
The available battery pack for the SW HMI panel N7 assembly is Detcon’s plug-in Smart Battery Pack
which provides an output of 12VDC and allows the assembly to be remotely mounted without the need for
any cables because of its wireless operation (See
Figure 4). If installed, the RXT-300 transceiver will
detect the battery and will continuously query the battery pack for remaining battery life. The battery pack
consists of rechargeable Lithium-Ion batteries and is equipped with integrated safety electronics that
include fuel gauge, voltage, current and temperature monitoring circuits. This “smart” circuitry
continuously monitors the battery’s condition and reports critical status information to the wireless
transceiver via the Modbus™ registers. The battery pack is designed to plug onto an 8-pin Beau connector
on the terminal board and should not be exposed to outside elements without being housed and protected.
Only Detcon products specifically designed to utilize these battery packs should be used. Operating
periods before recharge will vary based on devices attached along with the transceiver and the usage of
those devices, but can be as long as 2-3 months and battery life can be up to 5 years before battery pack
replacement is required. Improper use of the battery pack may be hazardous to personnel or the
environment and will void the warranty.

Figure 4 Smart Battery Pack
NOTE: The SW HMI panel can also be powered by a customer provided external DC power
source on connector J5 of the terminal board with a voltage range of 11.5-30VDC.
1.5 Quad Battery Charger (Optional)
Detcon’s Smart Battery Pack can be charged as needed using Detcon’s optional Quad Battery Charger
which can charge up to four battery packs at one time. The Quad Battery Charger comes with a plug-in
AC/DC adapter that plugs into a standard 120VAC outlet for power. The DC end of the adapter plugs into
the DC power jack of the charger providing 24VDC. The Quad Battery Charger has four charging ports,
each with 8-pin Beau connectors for battery pack connection. The ports and connectors are keyed to
prevent incorrect positioning and connection. Each port has its own “FAULT” LED indicator and
“CHARGE” LED indicator and will display either a red light or green light depending on the status of each
battery being charged. Charging times will vary depending on the charge state of each battery pack, but a
full charge of a depleted battery pack can take up to 24 hours.
Figure 5 Quad Battery Charger
When first powered on and with no battery packs connected to the charger, all the LED indicators on the
Quad Charger should be green. When a battery pack is seated into a charging port, the “CHARGE” LED
will change from green to red indicating the battery pack is not sufficiently charged. Once fully charged,
the LED will change from red to green and the battery pack is ready to be used.
The “Fault” LED should remain green indicating that there are no problems with the battery pack or
charging port. If the “Fault” LED turns red with the battery pack connected, then there is a problem or
issue with the battery pack and it should not be used and be removed immediately. If the “Fault” LED
