1. SENSOR POSITION
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 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 on page 5.
NOTE: The cap will reduce sensitivity. Test the unit as described in Alarm
Unit Function Test on opposite page 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 also
dependent on the depth of immersion. The unit will be more sensitive if
it is placed closer to the water surface.
