2GIG FTD100-345 Wireless Dual Flood Sensing Water and Temperature Sensor
The 2GIG FTD100-345 Wireless Dual Flood Sensing Water and Temperature Sensor is designed to help protect homes and businesses from water damage and temperature-related issues. This wireless sensor can detect the presence of water and monitor temperature conditions, giving compatible alarm systems an added layer of environmental protection beyond standard intrusion sensors.
Operating on the 345 MHz wireless frequency, the FTD100-345 communicates with compatible 2GIG alarm systems to report flood, leak, temperature, supervisory, low battery, and tamper conditions based on the system setup. It is a practical option for areas where leaks, standing water, or freezing temperatures could cause expensive damage.
Compatible Alarm Systems
The 2GIG FTD100-345 is designed for compatible 2GIG alarm panels that support 345 MHz wireless flood and temperature sensors. It can be used with supported 2GIG systems to add water and temperature monitoring to vulnerable areas throughout the property.
Dual Flood Sensing Design
This sensor uses built-in metal contacts on both the top and bottom of the device to help detect water without requiring an external probe. This dual-sensing design allows the sensor to detect leaks, pooling water, or standing water in the immediate sensor location.
Temperature Monitoring
In addition to water detection, the FTD100-345 can monitor ambient temperature conditions. This helps provide awareness for high or low temperature conditions that may indicate a problem, such as freezing risk, HVAC failure, or unsafe environmental changes.
Wireless Water Damage Protection
The wireless design makes this sensor easy to place in areas where water problems are most likely to occur. It is commonly used near water heaters, under sinks, near washing machines, by sump pumps, inside utility rooms, near HVAC equipment, and in basements or storage areas.
Switchable Encryption
The FTD100-345 supports on/off switchable encryption using an onboard switch. This allows the sensor to be configured based on the features supported by the compatible 2GIG alarm panel and the system programming requirements.

Important Compatibility Notice
Before purchasing, please confirm that your alarm panel supports 345 MHz wireless flood and temperature sensors and is compatible with the 2GIG FTD100-345.
This sensor is not a universal flood detector. It is intended for compatible 2GIG alarm systems and may not work with Honeywell/Resideo 5800 Series, Qolsys 319.5 MHz, DSC 433 MHz, PowerG, ProSeries SiX, or other alarm systems unless the specific panel configuration supports this device.
Encryption support may depend on the alarm panel model and system programming. Programming may require installer access to your alarm panel, and compatibility should be verified before ordering.
Flood detection performance depends on proper placement. The sensor should be placed where water is likely to collect or contact the sensing points. This device can help provide early warning, but it does not stop leaks, shut off water, or prevent damage by itself.
