MMTC 535T 318MHz 3-Button Wall Mount Transmitter

The MMTC 535T is a commercial-grade, wall-mounted wireless transmitter designed to remotely operate up to 27 commercial overhead doors or compatible motorized gates through Pulsar 318 MHz radio control systems. Featuring three dedicated Open, Close, and Stop pushbuttons and two rotary selector dials labeled A-C and 1-9, the 535T allows operators to select and control individual doors from a single stationary control location. The transmitter uses 318 MHz radio-frequency communication and an eight-position trinary DIP-switch coding system for integration with compatible Pulsar and Allstar three-channel receivers. Powered by a replaceable 9V battery, the unit eliminates the need for direct control wiring between the wall-mounted transmitter and remote door operators. Its compact housing measures approximately 5-3/4 inches high by 3 inches wide by 2-1/4 inches deep, according to MMTC's current product listing. Designed for warehouses, loading docks, distribution centers, industrial facilities, and commercial garages, the MMTC 535T provides centralized wireless Open/Close/Stop control for multiple powered door systems equipped with compatible receivers and required entrapment protection devices.

MMTC 535T Pulsar 318 MHz 27-Door Wall-Mount Wireless Open/Close/Stop Transmitter

The MMTC 535T Pulsar Commercial Door Transmitter provides centralized wireless control of multiple powered overhead doors and compatible automated gate systems from a single wall-mounted operating station. Designed for commercial and industrial facilities, the 535T incorporates three independently labeled Open, Close, and Stop pushbuttons that allow authorized personnel to send distinct operating commands to compatible three-channel radio receivers. Unlike single-door remote transmitters, the 535T can address up to 27 individual doors using two rotary selector dials, with one dial offering positions A, B, and C and the second offering positions 1 through 9. This configuration provides 27 selectable door combinations, such as A1, B5, or C9, allowing personnel to identify the intended door before transmitting an operating command. The stationary transmitter is particularly useful in warehouses, distribution centers, loading docks, industrial production facilities, maintenance buildings, and commercial parking structures where several motorized openings require operation from a common control location. Its wireless architecture reduces the need for separate hardwired three-button stations at a centralized operating point, provided that each controlled door has a properly installed compatible receiver.

The MMTC 535T operates on the 318 MHz radio-frequency band and uses an eight-position trinary DIP-switch coding system to establish communication with compatible Pulsar and Allstar receivers. Each coding switch supports three possible positions, allowing up to 6,561 theoretical code combinations across all eight switches. In multi-door installations, the first five DIP-switch positions establish the common transmitter-to-receiver code, while receiver switch positions six through eight correspond to the selected door number and letter combination. The transmitter includes a replaceable 9-volt battery, eliminating the need for external electrical power at its mounting location. MMTC's current product specifications list housing dimensions of approximately 5-3/4 inches by 3 inches by 2-1/4 inches, providing a compact stationary control enclosure for commercial applications. The transmitter's three-button layout separates opening, closing, and stopping functions to provide familiar operation for personnel accustomed to conventional commercial door control stations. The internal coding switches and battery compartment are accessible for maintenance and receiver configuration, while the wall-mounted design provides a consistent operating location for multiple door systems.

For multi-door commercial access applications, the MMTC 535T communicates with compatible Pulsar 318 MHz three-channel receivers connected to the Open, Close, and Stop control inputs of supported commercial door operators. Compatible receiver families include the Pulsar/Allstar 831 Series, with specific receiver compatibility and wiring determined by the installed equipment. The operator selects the desired door using the A-C and 1-9 rotary dials, then presses the corresponding command button to transmit an Open, Close, or Stop signal. The receiver interprets the incoming radio command and activates the appropriate output connected to the commercial operator. The 27-door selection architecture makes the 535T useful for facilities with multiple loading dock doors, warehouse bay openings, or other powered entrances requiring independent operation. Because it uses conventional fixed-code DIP-switch technology rather than encrypted access credentials, the transmitter is intended for operational door control rather than high-security user authentication. Its functionality also depends on the connected receiver and operator supporting separate three-button commands. All controlled openings must incorporate the appropriate safety and entrapment protection equipment required by the door or gate operator manufacturer and applicable installation standards.

Installation of the MMTC 535T wall-mounted wireless transmitter involves securing the control enclosure at a suitable indoor operating location, installing the required 9V battery, and configuring its DIP switches to communicate with the associated receivers. For a 27-door installation, the first five transmitter and receiver coding switches are matched, while receiver switches six, seven, and eight are assigned according to the manufacturer's door-selection table. Each receiver is connected to the corresponding commercial operator through its designated Open, Close, and Stop control terminals, with wiring performed according to the receiver and operator installation instructions. Once configured, the installer tests every A-C and 1-9 selector combination to verify that each command operates only the intended door. The 535T is part of a family of Pulsar commercial transmitters that includes the 831T for one door, 733T for three doors, and 639T for nine doors. Compared with these lower-capacity alternatives, the 535T provides the broadest door-selection capability within this wall-mounted three-button transmitter group. Routine maintenance includes checking battery condition, inspecting the control buttons, verifying selector operation, and testing receiver communication. Combining 318 MHz wireless operation, 27-door selection, independent Open/Close/Stop control, and battery-powered wall-mount installation, the MMTC 535T offers a centralized control solution for commercial and industrial facilities operating multiple motorized doors.
