2GIG FT100-345

The 2GIG FT100-345 is a wireless flood and temperature sensor made for 2GIG systems using the 345 MHz band. It monitors ambient temperature and also detects standing water at its probe. When conditions go outside your set high or low thresholds, or when water is present, it sends an alarm to the control panel.

The 2GIG FT100-345 is a wireless flood and temperature sensor designed to detect unwanted water and temperature changes in your home or business. This combined sensor monitors for the presence of water and reports it to a compatible 345 MHz wireless alarm system, helping alert you quickly to leaks before they turn into costly damage.

In addition to flood detection, the FT100-345 includes a temperature element that can report conditions such as freezing or rapid temperature swings. This dual-function design makes it useful for areas like basements, utility rooms, crawl spaces, attics, or near water heaters, where both moisture and extreme temperature changes may pose a risk.

This sensor typically mounts on or near the floor using the included bracket, placing the water detection probes in the path of potential leaks. When water is detected, the sensor sends a signal to the alarm panel, which can trigger local alerts, notifications through mobile apps, and monitored alarm reporting if you have central station service. The temperature element can also be used in home automation rules or alerts to notify you of potentially damaging freeze or heat conditions.

It uses a probe style design with a 45-inch cord, letting you place the sensing probe near potential flood zones (under appliances, near water pipes, basements) while mounting the main unit in a safe location. The FT100-345 is battery powered (one CR123A lithium) and offers up to five years of battery life in typical use.

This sensor is fully supervised and tamper protected, so your system knows when it’s online and secure. It is non-encrypted by default, but you can switch encryption on via the internal toggle for added security in modern systems. The FT100-345 pairs nicely with panels such as the GC Touch and 2GIG EDGE, making it a good choice for integrating environmental sensing alongside security.

The 2GIG FT100-345 is a practical choice for customers who want early warning of water leaks or temperature problems, helping protect property and reduce repair costs.
