PRODUCT DESCRIPTION
The USCG 46 CFR 28.250 & 182.530 compliant BG-HW is an electronic high water sensor that uses patented technology to detect the presence of
rising water. When water is detected the BG-HW will set the alarm wire to a high voltage state if the sensor on the bottom of the device is detecting
water. The alarm line can be used to drive an audible alarm or other device (up to 1 amp) to notify the operator and it is easily interfaced with the BG-CP
(Control Panel). The BG-HW is CE and ISO 8846 Marine Ignition Protection Certified, tested to ABYC-1500 standards.
The BG-HW can be tested and its status can be viewed using the BGI Config App, which can be downloaded from the App Store or Google Play. The App is
used on a mobile device with Bluetooth to wirelessly connect to the BG-HW device. The App will report the input voltage level, system temperature, and
alarm state. It also allows changing the name of the device for easy identification and testing the device.
INSTALLATION
The BG-HW is designed for mounting in any vessel compartment where
detection of the presence of water is required. A mounting bracket and
three #8x0.75” 316 stainless steel screws are provided to allow mounting
to a vertical or horizontal bulkhead structure.
The Blue Guard Installation Guide shows the wiring for all supported con-
figurations. All wiring connections are made using 14 gauge marine grade
wire. All wiring should be done by a licensed electrician following NEC
code.
INSTALL STEPS:
1) Locate proper mounting location for the BG-HW.
2) Install mounting bracket to bulkhead using two #8x0.75” stainless steel
screws provided.
3) Attach BG-HW to the mounting bracket in one of these three positions
with the wires facing up:
a. Horizontally with product label facing the bulkhead and the
mounting bracket below the sensor (See Figure 1).
b. Horizontally with product label facing up (See Figure 2).
c. Vertically with product label facing the bulkhead (See Figure 3 or 4).
4) Run wiring to the BG-CP (Control Panel) on the user supply panel and
battery depending on the installation chosen from the Blue Guard
Installation Guide. Secure the wiring using the optional BG-JBox. It is
recommended that connections to the BG-JBox be made using 14 AWG
crimp spade lugs at the ends of the wires.
5) Apply power to the system.
6) Connect to the BG-HW using the BGI Config App to view the status of
the unit and test, and set the unit name. The App can be used to view
the system parameters at any time.
*The BG-HW can also be mounted on the hull using three #8x0.75” 316 stainless steel screws.
Mount the strainer first, then attach the BG-HW into place.
