Cypress SPX-7400 Suprex Multimode Fiber Reader Extender

The Cypress SPX-7400 Suprex is a supervised multi-mode fiber optic reader extender designed to connect access control readers and door or gate hardware to remote access control panels. Featuring central and remote interface units, 8-16 VDC operation, and support for Wiegand credentials up to 248 bits, the system extends access control communication across fiber optic infrastructure. The base pair supports one reader, with expansion to eight readers using optional EXP-2000 module pairs.

Cypress SPX-7400 Suprex Multi-Mode Fiber Optic Access Control Reader Extender

The Cypress SPX-7400 Suprex Fiber Optic Reader Extender provides supervised communication between electronic access control readers, associated door or gate hardware, and remotely located access control panels. Designed for multi-mode fiber optic connections, the system includes a central unit installed near the access control panel and a remote unit positioned near the reader or controlled opening. The SPX-7400 supports Wiegand, magnetic stripe, and compatible clock-and-data reader interfaces, allowing existing access control equipment to communicate across fiber infrastructure. Its supervised connection monitors communication between the paired units, making the system suitable for parking facilities, perimeter gates, industrial properties, and buildings where extended cable distances or electrical interference complicate conventional copper wiring.

The SPX-7400 operates on an 8-16 VDC input with a maximum current requirement of 300 mA per unit and provides a 5 VDC auxiliary output rated at 100 mA. Its reader interface supports Wiegand data formats up to 248 bits, strobed clock-and-data signals, and F/2F communication, with field-configurable settings for compatible equipment. The multi-mode fiber interface uses standard ST connectors, with an 850 nm optical link and published loss budgets of 13 dB for 62.5/125 m fiber and 9 dB for 50/125 m fiber. Each unit features an extruded aluminum enclosure measuring approximately 4.5 x 3.08 x 2.02 inches. The manufacturer specifies an operating temperature range of -22 F to 140 F (-30 C to 60 C) and humidity tolerance up to 95% noncondensing. The enclosure is not rated for direct outdoor exposure.

The Cypress SPX-7400 incorporates supervised fiber optic communication, auxiliary input/output connections, and integrated relay controls for exchanging reader data and door or gate control signals between the remote location and access control panel. The relay interfaces support door strike activation, gate control, and compatible status signaling, with published maximum switching specifications of 1A at 220 VDC for resistive loads within a 30W limit and 1A at 250 VAC within a 37.5VA limit. Multifunction diagnostic LEDs display communication and configuration status, while dedicated operating modes support installation, testing, and troubleshooting. The system uses Cypress Suprex Lynk technology to support additional reader connections through compatible expansion modules. One SPX-7400 base pair supports a single reader and door or gate, while up to seven optional EXP-2000 expansion pairs increase capacity to eight readers over the same fiber optic connection.

The Cypress SPX-7400 Multi-Mode Fiber Optic Reader Extender is designed for access control installations where readers and associated door hardware are separated from controllers by long distances or electrically challenging environments. Manufacturer literature identifies a typical multi-mode fiber transmission distance of approximately 2 miles (3.2 km), subject to fiber type, optical loss, connector quality, and installation conditions. The system's surge-resistant fiber optic communication, removable terminal connectors, configurable reader formats, and supervised link operation support security applications at remote gates, industrial facilities, and distributed building entrances. The package includes both central and remote interface units, while EXP-2000 expansion pairs are available separately. Installers should verify fiber compatibility, optical loss budget, independent power requirements at both locations, relay loading, and reader interface specifications before deployment.
