Note the 9V battery installation—paying

attention to polarity, the battery should gently

bottom of the battery chamber.

RISK OF ELECTRIC SHOCK

NEVER install this alarm system outdoors. The system

is rated for indoor use only.

Sensor Installation

Sump Pump Sensor

1) Remove sump pump sensor from packaging.
2) Apply a small amount of glue to the inside of the snap feature of the

sensor.

NOTE: Over-gluing the sensor will make future removal

very difficult.

3) Snap sensor over the discharge pipe of your sump pump as shown

Figure 1

4) Route the sensor cable out of the sump pit and connect it to the

bottom of the alarm enclosure. See

Figure 3

Sewage Pump Sensor

1) Place the float switch cord into the clamp as shown in

Figure 2

2) Locate the clamp at the desired activation level and secure the

clamp to the pump discharge pipe as shown in

Figure 2

Note:

Do not install cord under hose clamp.

3) Tighten the hose clamp using a screwdriver. Over tightening may

result in damage to the plastic clamp. Make sure the float cable is
not allowed to touch the excess hose clamp band during operation.

Note:

All hose clamp components are made of 18-8 stainless

steel. See your Liberty Pumps

supplier for replacements.

4) Route the sensor cable out of the sewage pit and connect it to the

bottom of the alarm enclosure ensuring it does not interfere with the
operation of the primary pump’s float. See

Figure 3

Water Puck Sensor

1) Remove the puck sensor from its packaging.
2) Place sensor in the location susceptible to water intrusion or buildup

(example: under hot water heater, near laundry sink, near
problematic foundation wall, etc.).

3)  Route water puck cable such that it will not pose a tripping hazard.
4)  Plug water puck cable into the ALM sensor connector.
5)  Test water puck for operation by setting it in a small puddle or by

holding a damp towel on its bottom surface.

To install up to 3 sensors, use a Liberty alarm connector splitter
(sold separately, Kit: K001633).

Enclosure Installation

1) Select an indoor mounting location for the alarm unit. Liberty

Pumps recommends a location between 48in (1.2m) and 66in
(1.7m) above floor level.

2) Using the supplied template on the rear cover of this manual, mark

screw locations on the mounting surface.

3) If the screw locations are

NOT

directly over a wall stud, or the

alarm will be mounted to a masonry wall, the use of the supplied
anchors is recommended. A 3/16” (5mm) hole must be drilled
before inserting the anchor into the wall.

4) Mount the alarm enclosure to the wall using the supplied anchors

and screws (where applicable).
