Installation of the Alarm Panel
The ALM-P1 alarm panel is powered by 120 VAC coming from standard wall outlets which is transformed to 9VDC.
A 9 Volt battery provides battery back-up power so that the alarm will function in the event of a power failure.
When the water bridges the two probes, the alarm horn and light will turn "on" and the alarm panel's auxiliary contacts
will be activated. The rocker switch on the side of the alarm panel can be used to silence the horn.
Test product weekly. Make sure the green "power on" light is "on". Press the "Test" switch"; the red alarm light and
horn should turn "on". If the battery back-up system is utilized, unplug the wall mount power supply (the green light
will be off). Now press the " Test" switch; the red alarm light and buzzer will "on". If the buzzer sounds less loudly
than when tested with the normal power supply, then the battery should be replaced.
1. To install/replace the battery for the backup power feature, remove the two side screws and install 9 VDC
battery. After installing battery, press the test button to activate the alarm to make sure the battery works
properly. Reinstall side screws. See figure 4.
2. Determine mounting location for the Alarm Panel. Make sure power outlet is within 6 feet of the alarm. Make
sure the outlet is on a separate circuit breaker from any other device and not on a switched receptacle to
maintain power integrity. Mount the alarm using two #8 x 1-1/4" self tapping screws (not included). Use #8
plastic anchor if mounting to sheet rock. See figure 5.
3. If auxiliary contacts used, continue; otherwise go to step 4. Remove cover from base and remove ½"
electrical knockout from base. Use 16-2 AWG stranded wire – make sure there is at least 6'" of wire inside of
enclosure. Install a ½" strain relief with jam nut. Connect wires for required application using wire nuts.
Caution! – When installing wires, route all wires away from sharp objects & internal components. See figures
6 & 7.
4. There are two terminals on the bottom of the alarm panel. The red wire from the water sensor probe must be
connected to the "left" terminal, labeled R/W. The black wire from the water sensor probe must be connected
to the "right" terminal, labeled B.
5. Plug the power supply into a 120 VAC standard wall outlet. For UL applications, remove center screw on
receptacle and place cord from wall mount transformer inside the plastic cord holder. Secure plastic cord
holder to the receptacle by reinstalling screw to the center hole of receptacle. See figure 5. For Canadian
applications DO NOT INSTALL plastic cord holder! The green "Normal" light should come on.
6. Test the system by pressing the "Test" button. The horn and the red warning light will be "on". The green
"Normal" light will be "off'. While holding the "Test" button, switch the side rocker switch to the "Silence"
position. The horn will silence, but the alarm light will stay "on". Let go of the "Test" button and the alarm light
will turn "off" and the green "Normal" light will turn "on". Switch the rocker switch back into the "normal"
position and the system is now in operating condition.
