Instructions for
Model SS-4 Water Alert ®
(Model XSS-4 when using Sensor Cable)
PRINCIPLE OF OPERATION
Refer to Figure 1. The SS-4 is activated by liquid bridging the adjustable sensors (A & A). The unit can detect
water lm from zero height, (sensors turned out to make contact with the oor), to 1/8" height, (sensors turned
all the way in). The units are factory adjusted to activate with 1/32" water lm height which is satisfactory for
most applications. The pads B1, B2, B3 provide a gap between the case and the surface to admit water under
the unit for detection. CAUTION: If the pads are removed, the unit may form a seal with the surface and prohibit
the sensors from detecting water. If desired, the self-adhesive pad feature may be used by peeling o the thin
protective layer from each pad. The unit will remain in place when located on the mounting surface. Replace-
ment pads are available from Dorlen at no charge.

NOTE:
Although the two sensors (A & A) may be adjusted to make contact with the surface, it is recommended
that a small gap be set between the sensors and the surface so undesired activation, caused by damp-
ness or dirt lm, does not occur.

Instructions for
Model SS-4 Water Alert ®
To adjust sensor height, hold straight edge across
pads (B1 & B2). Turn sensors (A & A) out or until
distance to straight edge equals the desired water
detection level. See Figure 2.
Connect battery leads (E-E) to terminals of batteries
(C-C). Then insert the batteries into retainer clips.
Wait ten seconds, then test unit by touching wet
ngers to both sensors(A-A). The Relay should
transfer.
Position Water Alert in desired location and retest it
by placing wet ngers across the heads of the two
screws on which sensors are mounted The Relay
should transfer.
To reset the unit, simply remove it from water. If
necessary, dry o the sensor area if it is excessively
wet (if the unit was submerged).

CAUTION
BATTERIES
Two 9-volt alkaline batteries (NEDA size 1604A) are
required.
The Alkaline batteries should be replaced once a year.
If the unit is activated often, the batteries might need
to be replaced sooner.
Whenever the batteries are replaced, it is a good
practice to wipe clean the top surface of the Water
Alert and its sensors.
A Dorlen Power Supply, such as the PSW-3, may be
used in place of batteries. If so, follow the furnished
instructions for wiring.
