Matelec FPC-12650 Liquid Level Alarm Standard with Audio Buzzer DOWNLOAD OPERATIONS MANUAL NOTE: Float switch not included - optional extra The Matelec FPC-12650 is a robust liquid level alarm system designed to alert users when effluent, greywater, rainwater, or other storage tanks are either full or empty. It provides both visual (LED indicator) and audible (buzzer) warnings, with a user-friendly interface and flexible mounting options. This standard version is housed in a weather-resistant IP54 polycarbonate enclosure and includes a volt-free (dry contact) output for integration with external building management systems or auxiliary alarms. The system is triggered by a float switch (sold separately), with a safe 12 VDC input for easy low-voltage field installation up to 50 m from the monitored tank. An inbuilt mute function allows the buzzer to be silenced manually, or it will auto-silence after 5 minutes by default. For continuous alarms, the jumper can be repositioned on the PCB.
