on programming the Listen-in Time, High Sound Alarm Recognition
Time, and Sound Level Sensitivity (calibration).
Wiring Recommendations
The 1400 will work fine in indoor environments using unshielded
cable.Whenwiringwillbesubjecttolong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.
