The RF-S8 is a professional wireless receiver designed to seamlessly integrate the “S8” series of wireless sensors into the FLEXI SP3 control panel. Operating on a secure 868 MHz frequency, it enables your system to support wireless motion detectors, smoke sensors, sirens, and remote controls. With a reliable line-of-sight range of up to 500 meters, the RF-S8 is the perfect solution for creating flexible hybrid security systems in residential and commercial premises.
The central interface for all "S8" wireless devices. Easily add PIR sensors, magnetic door contacts, smoke detectors, and water flood sensors to your wired system without any extra cabling.
Utilizes high-performance 868 MHz radio technology to provide a stable link up to 500m. Ideal for covering large homes, multi-story buildings, and office spaces with a single receiver.
Connects directly to the FLEXI SP3 via the standard RS485 data bus. This ensures high-speed supervised communication and makes wireless sensors behave like integrated wired zones.
Features a dedicated "Learn" button and intuitive LED feedback for rapid sensor enrollment. Register new devices locally or remotely via TrikdisConfig software in seconds.
Exclusively designed for FLEXI SP3 control panels (firmware v1.22 or higher).
Supports a wide range of “S8” devices: PIR-S8, Door-S8, Smoke-S8, Flood-S8, and more.
Bidirectional communication for remote controls and sirens, ensuring command confirmation.
Operates on the 868 MHz frequency with 25 mW signal strength for optimal penetration.
Secure 4-wire RS485 bus connection (+DC, -DC, A, B).
Only one RF-S8 receiver is required per control panel to manage the entire wireless zone list.
Integrated SMA connector for an external RF antenna to optimize reception in shielded locations.
Low power consumption (max 100mA during transmission) for efficient battery backup.
NETWORK LED: Bi-color (Green/Red) indicator for sensor learning mode and enrollment confirmation.
POWER LED: Real-time feedback on supply voltage health and RS485 communication status.
Detailed RSSI (signal strength) monitoring for every enrolled sensor via TrikdisConfig.
Continuous supervision: the system alerts you immediately if any wireless sensor loses connection.
Rapid “Remote Linking” via Protegus cloud—no physical access to the receiver needed once installed.
Local configuration via integrated USB Mini-B port for firmware updates.
Built-in tamper protection detects unauthorized removal or housing opening.
Compact and discreet design (92 x 62 mm) for easy mounting inside panel boxes or on walls.
