Waterbug - 12 or 24 VAC or VDC (WB-200)Product Overview The WaterBug 200 ("WB200") is a water detection device ideal for computer rooms, document storage areas, warehouses, sump pumps and basements. WaterBug sensors activate the alarm when a conductive bridge is formed between 2 contacts. Protect your assets with the WB200.

Main Features:
Monitors for the presence of water. Can be used to detect the absence of water.
Device includes one standard unsupervised surface sensor (W-S-U).
Device accepts up to six total sensors (W-S-U). Additional sensors (W-S-U) sold separately.
1 to 2 sensors can be located up to 200' (60.96m) or 3 to 6 sensors can be located up to 100' (30.48m) away from the device for a wide area of protection. Use 18-22 AWG twisted pair wire for extension of sensors from the device.
Hard wire powered device. Ensure that the power running to the device does NOT have a connection to earth ground. This could result in a failure to detect water or ground fault.
Power requirements of 8 to 28V DC at 35mA or 12 to 28 V AC at 100mA
Unit operating range of 32 to 130 F (0 to 54 C) in non-condensing environment. Indoor use only.
Output is 1 Form C (N.O./N.C.) with 30V DC at 1 Amp resistive/24V AC at 1 Amp resistive
Dimensions of 4.1" x 2.36" x 1.18" (10.4cm x 6.0cm x 3.0cm) .
