Wireless Dry Contact Sensor for Sensaphone 2800

Wireless Dry Contact Sensor


The WSR-0101 Wireless Indoor Dry Contact sensor is designed to work with the Sensaphone 2800 Environmental Monitoring System. This sensor includes a built-in radio transmitter and input terminals for connecting to any normally-open or normally closed output. (Use of this device with solid-state outputs is not recommended.) The sensor comes with 3 AAA alkaline batteries which will power the sensor for up to 3 years. An optional plug-in power supply is also available. The batteries then become a backup if main AC power fails.
