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 SW-
HMI-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
