If your wall outlet has a screw in the middle of the wall plate, Note that there is a hole located at the top of the power supply housing. Note: The star connector is required to scratch the paint off of the cabinet. Using one of the existing holes in the cabinet (alarm panel box), bolt both wires to the cabinet as indicated above:īolt, cabinet hole, star washer, long ground wire to building ground with ring connector, lock washer, nut, short ground wire with ring connector, lock washer, nut.įor this specific alarm system, all of these parts were included in the kit. Then, cut another short length of wire and connect a ring connector to one end of that wire. To ground the cabinet, connect a ring connector to the end of the ground wire. Grounded, that lose wire will be grounded in case it comes in contact with the cabinet. This is done in case a power wire comes lose and contacts the cabinet. The alarm system also recommends that you also ground the metal alarm panel box.
Your home should already have a VERY thick wire that is clamped to this ground connection and run to the electrical box.Īlso, any coaxial cables for cable TV or satellite will also be grounded right as they enter the home and you can either leverage that ground or trace it back to the grounding clamp.įinding a good ground is another good reason to locate the alarm panel with other wires in a basement or utility closet. There is no need to figure this out for yourself. Tapping the building's main ground normally means clamping a wire to the copper water pipe as a ground or connecting it to a driven ground rod. This is easy for me because my wiring panel (which is only a couple of feet from the electrical box) already has a direct ground connection for other wiring. I prefer to tap directly into the building's main ground. You could run the ground from the ground connector on the power supplyĪnd it will work since this ground will run back to the electrical box and then to the building's main ground. To differentiate the positive and negative wires.įor this alarm, the ground is located at the opposite end of the circuit board. Usually your power wire will be colored, labeled with + or -, or will have a stripe (for power) Connect the + terminals together and the - terminals together. Typically, both the power supply and alarm panel will have power connections The power supply will either have 2 screw terminals (+, -) or 3 terminals (+, -, ground). Using 18 AWG or better wire, measure the length of wire needed to connect the power supply at the power outlet to the power terminals on the circuit board.įirst connect the wires to the power supply, then the wires to the alarm panel, and then finally plug in the power supply to the electrical outlet. Connect the ground first (black), and then the power (red). The wire colors will be red & black which match perfectly the red and black terminals on the battery itself. Buying the recommended BD7-12 battery or purchasing the battery, power supply, and main board in a kit is easier. In this case, they should both be 12 volt 7 amp-hours. First, verify that the power requirements of the circuit board match those of the battery. For this alarm system, the wires for the battery come directly out of the side of circuit board.
