POOL PATROL PA-25 & PA-30
To connect to a home security system there is a connector at the bottom
of the receiver with three inputs: (See Figure 11)
The home security system will connect to two of the three terminals.
Check the security system documentation to determine if the system is
an “open loop” or a “closed loop” system. These inputs are connected to
a relay and only provide an open or closed contact.
Closed Loop
If the security system is closed loop, the connections are made to the
“C” and “NC” terminals. When the receiver alarms the relay will open
and trigger the home security system.
Open Loop
For an open loop system, connections are made to the “C” and “NO”
terminals. When the receiver alarms the relay will close and trigger the
home security system.

INSTALLING OR CHANGING THE BATTERY
The pool alarm requires a 9V alkaline battery. One 9V alkaline battery
will last for one year under normal use. The battery is in a compartment
under the floatation base. You will need a Philips screw driver to remove
the battery cover.
1) Turn the alarm
upside down. Note the black
floatation base and the words
“BOTTOM” and the word
“SENSITIVITY” with an arrow
to “INCREASE” or
“DECREASE” the sensitivity.
To remove the float, turn the
black flotation base in a
counter-clockwise direction
or in the “DECREASE”
direction, until the base is
loose from the upper blue
housing. Figure 1 is a picture
of the battery cover with the float removed.
2) Once the floatation base is
off locate the battery cover
(Figure 1). Remove the
two screws and lift off the
battery cover and gasket
exposing the 9V battery
clip.
3) Snap a 9-volt alkaline
battery on to the battery
clip (Figure 2) and
carefully insert the 9V
battery and clip into the
battery compartment.

IMPORTANT
Use only a 9V alkaline battery. Be careful when installing or
removing the battery as the battery clip can break.
