Wiring Recommendations -
The FARMsitter will work fine in indoor environments using unshielded cable. When wiring will be subject to lengths (>250') or if run outdoors, it is highly recommended that shielded cable be used and that the shield be connected to an earth ground. Also, be sure to use the appropriate gauge wire based on the distance and sensor type. See chart below:
 
Wire Gauge Thermistor NO/NC Contact & 4-20mA
#24 250' 1000'
#22 500' 2000'
#20 1000' 4000'

Communications -
The FARMsitter is compatible with telephone answering machines/voicemail and rings up to 15 times for an answer. It will mute speaker during alarm call and has an alarm acknowledgement via pulse or touch-tone call. It supports pulse or touch-tone and has 3 3/4 seconds of recordable voice for each sensor zone. The FARMsitter also has six seconds of recordable voice for location ID with voice repetition up to 10 times. Eight dial out telephone numbers up to 48 digits and call delay until the first call is made up to 60 minutes, also time delay between alarm calls of up to 60 minutes.
