Configuring a SeaHawk Device as an Analog
Input
Users with legacy systems may find this information useful. The FMS averages/filters the
analog inputs.Therefore, the alarm delay for RLE’s SeaHawk LD5100 input must be set to a
value equal to or greater than the averaging time set in the FMS. The LD5100 will output 4mA
when there is no leak. The LD5100 will output a value between 4mA and 20mA when there is
a water leak. The low range (4mA) will always correspond to zero feet. The high range
(20mA) will always correspond to the LD5100’s set 4-20mA Max Range (1000, 2500, or 5000
feet).
