Sensitivity Adjust
1. Sensitivity adjust switch
The most effective way to adjust the
sensitivity is to move the sensor
adjust piece located at the bottom of
the sensor tube.
Loosen the two screws on the bottom of
the sensor.
Move the plastic piece with the pointer
pointed to “H” if you want higher
sensitivity or to “L” if you want lower
sensitivity. The unit is preset at factory
to “H”
If you have to place the unit near the return water flow, snap the cap onto
the sensor cage facing the direction of water flow. See Pool Side
alarm Mounting.
NOTE: The cap will reduce sensitivity. Test the unit as decribed in Alarm
Unit Function Test before use.
2. Depth of immersion
The patented design sensor can pick up underwater
wave motion caused by an object falling into
water.The sensitivity of this sensor is dependent
on the depth of immersion. The unit will be more
sensitive if it is placed closer to the water surface.
