Installation of the Water Sensor Probe with SumpJet® Model SJ10
The ALM-P1 was specifically designed for use with the SJ10 water-powered backup sump pump. With the water
sensor probe in the correct position, the alarm will activate before the pump activates, to let you know when the SJ10
backup is in use. During a power outage, the rocker switch can be deployed to the “silence” position to eliminate the
alarm from going off multiple times. The switch should be returned to the “on” position after the power outage has
ended, for normal operation.
1. The correct position for the water sensor clamp is already determined on the SJ10, to trigger just before the
pump activates. The clamp should be placed on the intake pipe of the SJ10 pump, with the bottom of the
clamp touching the top of the pump’s foot valve. If the clamp is not positioned directly against the foot valve,
the alarm may not function properly. The clamp should be rotated so that the probes face away from the SJ10
float. See figure 3.
2. 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.
3. 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.
4. 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.
