Ifvertical mounting is employed, the switch endshould be facing downwards to reduce theaccumulation of grease and dirt on the switchend.
Insure that proper protection for the beacon is provided i. If vertical mounting is employed, the switch end should be facing downwards to reduce the accumulation of grease and dirt on the switch end. Kd120 water switch is part of a low current triggering circuit, which when closed will initiate normal pulsing of the beacon oscillator circuit.
Position mounting kit carefully to avoid interference with other structures. Connect test leads as shown in Figure 22 and check for current leakage between battery and beacon body. The beacon should be mounted horizontallywith the switch end forward, if possible.
