The UNITED SECURITY PRODUCTS f20 is a temperature switch sensor designed to detect changes in ambient or surface temperature and trigger a corresponding signal in a security or monitoring system. This type of device is commonly used in applications where temperature thresholds must be monitored and an alert or control action is required when those thresholds are crossed. Licensed security installers and systems integrators are the typical trades who work with this device. The f20 is a compact, field-installed component suited for integration into broader alarm or building automation panels.
The f20 temperature switch sensor is used in residential and light commercial security and monitoring installations. It is appropriate for environments where abnormal heat conditions, such as those caused by fire, equipment failure, or HVAC malfunction, must be detected and reported. The device connects into a security panel or monitoring loop to provide automatic temperature-based alerts.
Designed as an OEM-style replacement or add-on temperature sensing device for compatible security panel and monitoring system installations.
Installation is typically performed by a licensed security systems technician or electrician familiar with low-voltage wiring practices. Disconnect power to the security panel or monitoring system before making any wiring connections to the f20. Follow all applicable local codes and manufacturer panel documentation when integrating this sensor into an existing loop. Verify polarity and loop resistance requirements at the panel before placing the system back into service.
