Features:<\/strong>
\nConnection:
\nThe SDX-RTX transmitter links to the SDX-15 Alarm system via 2-core data bus cable.
\n4no input signals are wired from each gas (plant or manifold), via an end-of-line termination board, knowns as a TB4 PCB (optional).
\nEach gas requires upto a 5-core cable (4no switched conditions and 1no Common) and up to 4no gases can be in-putted via 1no SDX-RTX<\/p>\n

Maintenance:
\nTransmitter PCB requires a 230vac supply.
\nAll supply, input and data-bus terminations are via simple 45deg PCB mounted terminals.<\/p>\n

Application:
\nThe SDX-RTX is manufactured in a 1, 2, 3 or 4 channel (gas) variation, to suit the customers needs.
\nThese transmitters can also be upgraded to add or delete channels without the need to re-install new\/additional enclosures and supplies.<\/p>\n

The transmitter incorporates a single channel selector switch which determines the transmitted channel for the first gas (marked on the PCB as Service A). Where additional gases are required, the SDX-RTX will transmit as follows:<\/p>\n

Service A \u2013 Transmitted on channel selected by rotary switch (channel always used)
\nService B \u2013 Transmitted on channel selected by rotary switch plus 1, (used on one and two gas variations only)
\nService C \u2013 Transmitted on channel selected by rotary switch plus 2, (used on one, two and three gas variations only)
\nService D \u2013 Transmitted on channel selected by rotary switch plus 3, (used on four gas variation only)<\/p>\n

The SDX-RTX transmitter receives 4no analogue signals from up to 4no gases (plant or manifold) and then transmits these signals via a 2-core data-bus using Shire Controls own Medcon signal protocol. A single 2-core data-bus can transmit up to 60 status conditions (15no gases, each with up to 4no condition) and channels are determined via hexadecimal (16 way) rotary switches for transmitting (via SDX-15 transmitters) and receiving for display purposes (via SDX-15 Plant Alarms) or for interfacing to others (via SDX Computer Interfaces).<\/p>\n

For monitoring of input signal wiring, a termination box is required to be mounted as close as practical to the gas source. The integrity of the cabling between the gas source and the SDX-RTX is monitored, and a fault on this cable will result in visual system fault warning, with all affected alarm conditions going into alarm condition.<\/p>\n

Monitoring of the data-bus connection is always in operation. The transmitter looks to receive a strobe signal from the designated \u2018Central Panel\u2019 (the 24-hour monitored SDX-15 Plant Alarm), which ensures the system data-bus integrity. Any short-circuit, open-circuit or non-presence of a Central Panel will result in the transmitter giving a visual warning of this system fault.<\/p>\n

As the system is addressable, ALL SDX-15 system equipment (Alarms, Transmitters and Interfaces) can be added\/removed or relocated within the system. This simply requires the 2-core data-bus to be extended from the nearest existing SDX-15 Unit, or tee-ing off from a nearby existing cable run. Use 2-core screened cable (minimum 0.5mm).<\/p>\n

PCB LED Indicators:
\nSDX-RTX has 3 5mm round LED indicators \u2013 Green, Yellow and Red:<\/p>\n
