Supplemental Installation Instructions for your ALM-P1 Alarm
Product Description
The ALM-P1 is an alarm system that utilizes a water sensor connected to an alarm panel to detect a high water
situation in a sump pump application. The sensor clamps on to 1-1/4" or 1-1/2" PVC pipe. When water bridges the
probes, the alarm box will activate an alarm light and horn. The horn can be silenced by switching the rocker switch on
the side. The alarm light will still function even when the horn is silenced.
Installation of the Water Sensor Probe on discharge pipe
1. The water sensor for the ALM-P1 was designed to be installed directly onto a pump discharge pipe. The clamp will
only fit onto 1-1/4" or 1-1/2" pipe. See figures 1 and 2.
2. Determine correct height for the water sensor. The alarm will turn on when the bottom of the probes detect water.
The correct height for these probes should be above the turn on point of the pump and well below the top of the
sump pit.
3. Connect wires from water sensor to the alarm panel. Red wire must be connected to the "left" terminal, labeled
R/W. The black wire must be connected to the "right" terminal, labeled B. Wire up to the panel can be secured to
the pipe with the included zip tie.
4. Test the pump and the turn on level of the alarm. When satisfied with the probe position, mark the level on the
discharge pipe. For added security, slide the probe clamp away from intended position and apply a small amount
of PVC glue to the discharge pipe. Return the alarm probe to desired position. The PVC glue will bond the pipe
and clamp to prevent accidental movement.
5. To test the water sensor, immerse both probes in water or place a wet rag or sponge across the probes. The
alarm panel should activate. Completely wipe and dry the probes before putting the unit back into service.
