Temperature Sensor Olympia FST 200 Freestanding Wired

The Olympia FST 200 Freestanding Wired Temperature Sensor is a compact wireless temperature transmitter designed to work with Olympia Protect 6xxx/9xxx series security systems. It measures temperatures from -50°C to +70°C with an accuracy of ±1°C and performs automatic readings every 30 seconds. The unit includes an external temperature probe on a 1.5 m cable, an integrated 868 MHz radio module for communication with the Protect 6xxx/9xxx series, a display for current and min/max temperature history, and multiple mounting options: desktop, wall-mount or magnetic fixture. The device is battery powered and its housing measures 71.5 × 65 × 21 mm.

Advantages

The sensor provides reliable temperature monitoring with a wide measuring range and stable accuracy of ±1°C. Integrated 868 MHz communication ensures direct compatibility with Olympia Protect 6xxx/9xxx security systems without additional gateways. The external probe and multiple mounting options allow flexible installation for chest freezers, upright freezers, aquariums and other environments, while the min/max history and 30-second measurement cycle give clear traceability of temperature changes.

How to use

Place the temperature probe at the desired measurement point and position the main unit on a flat surface, mount it on a wall, or attach it magnetically. Insert the batteries, power the unit, and ensure the device is within range of the Olympia Protect 6xxx/9xxx security system so the integrated 868 MHz module can pair and transmit readings. Use the display or the connected alarm system to view current temperature and toggle min/max history as needed. Check battery status periodically to maintain continuous operation.

Recommendations

Install the probe inside the monitored compartment (for example, inside a freezer) rather than on the unit housing for the most accurate readings. Maintain the probe cable routing to avoid mechanical damage and verify wireless range to the Protect control panel before permanent installation.
