ALM-2R (Wireless) Alarm Installation Instructions
The ALM-2R alarm system features a battery operated wireless transmitter that is placed in a tank (up to 150 feet away from the
indoor alarm). When the high water alarm fl oat switch activates, the transmitter sends a signal and sounds the indoor alarm warning
of a potentially threatening liquid level condition. The horn can be silenced, but the alarm light remains on until the condition is
remedied. Once the condition is cleared, the alarm will automatically reset.
The ALM-2R alarm system monitors liquid levels in lift pump chambers, sump pump basins, holding tanks, sewage, agricultural,
effl uent fi lters, and other water applications.

ELECTRICAL SHOCK HAZARD
Disconnect power before installing or servicing this
product. A qualifi ed service person must install and
service this product according to applicable electrical
and plumbing codes.
Failure to follow these precautions could result in serious injury or death. Replace product immediately if switch cable becomes damaged
or severed. Keep these instructions with warranty after installation. This product must be installed in accordance with National Electric Code, ANSI/
NFPA 70 so as to prevent moisture from entering or accumulating within boxes, conduit bodies, fi ttings, fl oat housing, or cable.
EXPLOSION OR FIRE HAZARD
Do not use this product with fl ammable liquids.
Do not install in hazardous locations as defi ned by
National Electrical Code, ANSI/NFPA 70.
INSTALLATION REQUIREMENTS
1. Please note the following requirements when determining
a location for installation:
Do not mount the transmitter more than 2" below
ground. The further below ground the unit is
installed, the shorter the range becomes.
Do not use a metal riser cover. It will severely
limit the range of the unit.
Note what is between the receiver and transmitter.
An RV, pole shed, or any large metal object may
cause transmission problems. Individual vehicles
such as cars and SUV's will not be a concern.
The transmitter and receiver operate on a line-of sight basis; where the signal goes straight to the
receiver. Steep inclines may cause there to be no
clear line of site between the receiver and the
transmitter. (See Figure E on back page.)
Metal buildings and buildings with aluminum siding
may cause the unit to have a shorter range. In
some cases, it may be better to mount the receiver
unit on a wall perpendicular to the transmitter.
AC equipment used continuously in excess of 3
hours may cause loss of transmission alarm.

INSTALLING THE RECEIVER (ALARM)
1. Determine the location of the receiver (alarm) unit. Please
note the following requirements when determining a
location for mounting the receiver:
Do not install receiver (alarm) in a basement.
Do not install receiver (alarm) near a computer or
radio. These items may limit receiver's ability to
pick up a signal.
Mount receiver (alarm) as close to transmitter
(fl oat) as possible. (Do not exceed 150 feet.)
Mount receiver and plug it into a 120 VAC wall
outlet.
2. Insert screw (supplied) at desired wall location.
Note: Screw is to be located over wall stud or used with
a wall anchor sized for a #8 x 1.25" self tapping screw.
3. Hang alarm using keyhole on back of enclosure. Install
second screw in mounting fl ange located on bottom of
alarm.
4. Make sure power to alarm is disconnected.
5. Bring optional alarm fl oat cable leads back to receiver unit
and wire according to Figure A. Note: When used with
a pump application, install optional 9 VDC battery This
allows the receiver to operate if the pump circuit fails.
6. To install backup alarm battery (optional), open battery
door and install 9 VDC alkaline battery (not included).
Do not use heavy duty/non-alkaline batteries. Battery
must be installed for backup alarm to function. Note:
The green power on light does not illuminate when unit
is on battery power.
7. Plug the alarm in to apply primary power . Verify the green
"power on" light illuminates.
8. Install 3.6 VDC lithium battery pack into the transmitter.
9. Check operation by manually tipping fl oat up. After a 10
second delay, the horn will sound and the "alarm" light
will come on.
10. Press "silence" button to silence the horn. The horn will
silence while the red "alarm" light stays on.
11. Tip fl oat back down. After a 10 second delay the alarm
light will turn off. Press "test" button. The "alarm" light
and horn will activate.
12. Reset the alarm by removing all 120V and 9 VDC power.
Remove the 3.6 VDC battery from transmitter. Reapply
power to the receiver unit. Do not insert transmitter
battery at this time.
12. Replace 9 VDC battery every 12 months and after each
alarm condition to ensure proper operation. If battery is
low, the low battery chirp feature will cause the horn to
chirp approximately once per minute. Replace battery if
this occurs. Note: Non-alkaline batteries may cause a
low battery chirp even when they are new.
13. Using the provided cable clasp, secure cord to outlet
as shown in Figure B. Use existing receptacle faceplate
screw and supplied washer.
14. Test unit once per week to insure proper operation.
INSTALLING THE TRANSMITTER (FLOAT)
NOTE: DO NOT CUT FLOAT CABLE.
1. To monitor high level conditions determine the correct
activation level for the fl oat.
2. Suspend switch at desired activation level as shown
in Figure C. Note: Switch remains partially submerged
during "on" tipping action.
3. Set fl oat height and coil any excess cord. Secure with
zip tie provided.
4. To mount the unit in a 4 or 6 inch PVC pipe, drill a 1 3/8
inch hole in the top of the PVC cap and mount transmitter
through the cap as shown in Figure D.
5. Reinstall battery and place back inside unit.
6. Apply thread compound that is suitable for PVC to threads
of holder. Do not use tefl on tape.
7. Replace grey cap. Wait at least three minutes. Once
battery is installed, the transmitter will wait three minutes
to transmit a signal. During the 3 minute wait, drop the
fl oat into place and replace all tank covers.
8. After three minutes have elapsed, press and hold "test"
and "silence" buttons on receiver. A fl ashing green light
signifi es a good installation. A fl ashing red light signifi es
either the unit did not receive any signal or the signal was
not strong enough for reliable operation. Move receiver to
a different location. Note: A change in location as minor
as moving it up vertical one foot could allow it to operate
reliably.
9. Replace battery every 2 years.
