DWYER USA ABS Plastic Water Leak Detector, Power Source : Battery

Water Leak Detector

The very affordable Series WD2 Detects Leaking Conductive Fluids and alarms to prevent the leak from creating costly damage. The WD2 relies on the electrical conductivity of water to change the resistance across the two contacts located at the base of the enclosure. Model WD2-BP2 is battery powered, provides audible alarm, LED visual alarm,and a SSR output.Also featured is a low battery warning. WD2-LP units are line powered and include a green power indication LED.

Mounting bracket A-154 is perfect for use in leak pans where it is desired to raise the sensing level above the bottom of the pan to eliminate nuisance alarms. The bracket can be mounted to the bottom of the pan and the height of the WD2 adjusted anywhere up to 1.75 ¿¿ (44.5 mm).Or the bracket can be used to mount the WD2 to the side of the drip pan or any side wall at desired height.

Operation:

Model WD2-BP2 is battery powered, provides audible alarm, red LED visual alarm, and a SSR output. When conductive fluid is detected, the audible alarm will turn on for 10 seconds followed by a 30 second visual alarm repeated until the unit no longer detects fluid. The SSR will change state from open to closed. When the battery gets low the WD2 gives a warning by turning on the visual and audio alarms.

WD2-LP units require an 11 to 27 VAC/DC power supply. A green power LED illuminates when the unit has power. WD2-LP units provide audible alarm, red LED visual alarm, and either a SPDT or DPDT output. When conductive fluid is detected, the audible alarm and visual alarm will turn on and stay on. The relay will change state with open contacts going to closed and closed contacts going to open.

Mounting:

The unit is made to place on a horizontal surface where leaking fluid can build up.

Mounting bracket A-154 is perfect for use in leak pans where it is desired to raise the sensing level above the bottom of the pan to eliminate nuisance alarms. The bracket can be mounted to the bottom of the pan and the height of the WD2 adjusted anywhere up to 1.75 ¿¿ (44.5 mm). Or thebracket can be used to mount the WD2 to the side of the drip pan or any side wall at a desired height.

The A-154 includes one “U” bracket and two “L” brackets. For bottom mounting unscrew the body screws in the top of the WD2. Install the “L” brackets to the “U” bracket sides using the screws and nuts provided. Keep the screws loose for later adjustment of WD2 height. Place the “U” bracket on the top of the WD2 and line up the holes in the bracket with those in the body. The A-154 includes longer body screws that are used to now screw down both the bracket and the body top. The “U” bracket can be mounted in the up or down orientation but it must be mounted “down” to reach the full 1.75 ¿¿ height potential
