We have had customers run wire up to 1000′ using Shielded 18GA Wire with success. We can’t recommend or guarantee that this will work but we have customers do this with success. Click here – http://www.absoluteautomation.com/18-awg-stranded-two-conductor-wire/ – for our recommended wire.
No, none of the Freeze Alarm or Temperature Guard products can monitor more than one temperature sensor. However the Sensaphone 400 can monitor up to four!
No, the Freeze Alarms cannot do this. However the Sensaphone 400 can do this.
It begins to overwrite the oldest samples with current readings.
