MS Sedco S-TRX ClearPath Spectrum Wireless Radio Control Transceiver for Automatic Door Activation

The MS Sedco S-TRX is a commercial-grade transceiver that forms a core component of the ClearPath™ Spectrum Wireless Radio Control System, engineered to deliver the most reliable wireless activation of automatic doors available. Operating at 2.4 GHz, the S-TRX leverages a shorter wavelength more than 5 times shorter than commonly-used frequencies, allowing signals to pass through cracks and barriers with greater ease. When used in conjunction with the S-COR Coordinator, the S-TRX provides digital two-way communication for enhanced security and confirmed signal transmission, and comes prewired and installed with a battery in a mounting box for straightforward deployment in commercial door hardware applications.

Key Features

  • 2.4 GHz Operating Frequency: Operates at 2.4 GHz, producing a wavelength more than 5 times shorter than commonly-used frequencies for superior penetration through walls, cracks, and barriers.
  • Digital Two-Way Communication: Industry-first digital two-way communication ensures greater security and confirms successful signal transmission between the S-TRX transceiver and the S-COR Coordinator.
  • Persistent Signal Transmission: Transceivers continuously attempt to contact the Coordinator until an acknowledgement is received, eliminating missed activations in demanding environments.
  • Real-Time Device Diagnostics: Upon switch activation, the S-TRX communicates device ID, signal strength, and battery monitoring data, all displayed on the S-COR's LCD screen for quick visibility.
  • Multi-Device Pairing: Supports pairing of multiple S-TRX Transceivers with S-COR Coordinators, enabling scalable wireless door activation configurations.
  • Shared PCB Platform: ClearPath™ transmitters share the same printed circuit board (PCB), ensuring consistent performance and simplified parts management across the product family.
  • Ready-to-Install Design: Comes prewired and installed with a battery in a mounting box, reducing installation time and complexity for commercial door hardware professionals.
  • S-COR Coordinator Compatibility: Designed for use with the S-COR Coordinator, which features an LCD screen for quick and easy programming of the Spectrum Wireless System.

MS Sedco S-TRX – Frequently Asked Questions

1) Does the MS Sedco S-TRX transceiver work on its own, or do I need something else to run it?
The S-TRX is one half of a system. It talks to the S-COR Coordinator, and that pairing is what gives you the digital two-way link, the acknowledgement handshake, and the diagnostics readout. Without an S-COR there is nothing to receive the activation and nothing to program the device against. If you are pricing out a wireless push plate or switch activation for an automatic door, budget the coordinator plus one S-TRX per activation point.
2) How many wireless activation points can I run back to one ClearPath Spectrum coordinator?
Multiple S-TRX transceivers pair to S-COR Coordinators, so a vestibule with an exterior push plate, an interior plate, and a staff switch can all report to the same coordinator. Each transceiver sends its own device ID on activation, so the coordinator's LCD tells you which one fired. That is how you scale a multi-door or multi-button entry without running wire between the openings.
3) What switch rating does the S-TRX use, and will it take the push plate or switch I already have?
The S-TRX carries a UL Listed SPDT momentary microswitch rated 15A at 125VAC. Any dry-contact momentary device that closes a normally-open circuit is the kind of input it is built around. It arrives prewired with the battery installed in a square surface mounting box, so the install is mounting the box and making the switch connection rather than building the unit up on site.
4) Do I have to run power or low-voltage wire to the S-TRX transceiver?
No. The transceiver ships with a battery installed and runs about three years on it, so the activation point needs no power run and no conduit back to the operator. For a retrofit where the push plate sits on a glass wall, a stone column, or across a vestibule from the operator, that is the whole reason to go wireless. Plan on a battery swap roughly every three years; the coordinator shows battery monitoring data so you are not guessing when.
5) What happens if a wireless activation signal gets missed or blocked at the door?
The S-TRX keeps trying. It transmits repeatedly until the coordinator acknowledges receipt, rather than firing once and hoping. That acknowledgement handshake is the difference between this and a one-way transmitter, where a dropped signal is simply a door that did not open and a person standing there pressing the plate again. In a hospital corridor or a high-traffic retail entry, that persistence is the specification detail worth paying for.
6) Why does the ClearPath Spectrum system run at 2.4 GHz instead of the usual door radio frequencies?
2.4 GHz is a wavelength more than five times shorter than the frequencies commonly used for door activation, and shorter waves get through cracks, gaps, and barriers more readily. In practice that matters where the signal has to cross a masonry vestibule, a metal door frame, or a wall between the push plate and the operator. The tradeoff a specifier should know: this is the same band as facility Wi-Fi, which is why the digital two-way protocol matters here.
7) Can I tell which wireless door button is weak or losing battery before it fails?
Yes, and that is the maintenance case for the Spectrum system. Every time a switch is pressed, the S-TRX reports device ID, signal strength, and battery status to the coordinator, and the S-COR shows it on its LCD. A facilities tech can walk to the coordinator, press each plate, and read signal strength at every activation point instead of chasing an intermittent door. It also means you can verify range during commissioning rather than after the complaints start.
8) How do you program an MS Sedco Spectrum wireless transmitter to the receiver?
Programming happens at the S-COR Coordinator, which has an LCD screen for setup rather than dip switches or blind learn buttons. You pair each S-TRX to the coordinator through that display, and the same screen is where device IDs and signal readings appear afterward. For an integrator, that means one place to add, verify, and troubleshoot every activation point on the system.
9) Is the S-TRX a commercial-duty door control or is it suitable for residential use?
This is commercial-grade equipment for automatic door operators, not a residential garage or gate remote. It is specified into hospital and clinic hands-free entries, school entrances, retail storefronts, warehouse access points, government buildings, and multi-tenant residential lobbies. If you are looking for something to open a house door, this is the wrong class of product entirely.
10) If I add more S-TRX transmitters later, will they behave the same as the ones already installed?
They will. ClearPath transmitters share a common printed circuit board across the family, so performance is consistent between units and you are stocking one board rather than a different spare for every device on the job. For a property manager standardizing wireless activation across a portfolio of buildings, that keeps the spare parts drawer small.
