Your alarm may sound at this point. Don your insulated rubber gloves and unscrew the faceplate from the control box. Remove the black and red wires feeding into the backup battery pack. If the alarm was sounding, it should stop once the battery pack is removed.
1. Locate the bottom of the sensor (the slotted flat end), and then use a screwdriver to remove the casing's screw. 2. Gently slide a fingernail/fingertip into the slot and push the top casing of the sensor outward, away from the wall.
First, turn off the power. Then locate the sensor and access the terminal block. Verify that the power is off by measuring voltage at the sensor terminal block. Lift the wires, separate and insulate them.

In most cases, your new alarm company will use the current wiring. If not, don't hesitate to reach out to a professional, like an electrician, for assistance. Depending on your circumstances, your current or soon-to-be former security provider might also be willing to give you additional support.
Most security and alarm cables are typically rated to very low voltage (12V, 120V, 300V or some other low voltage) because many of them do not supply power.
Most garment security tags have 1 or more pins inside that secure the cartridge to the body of the tag. You may be able to cut the wire if you can manage to get a wire cutter between the 2 halves of the tag, but these pins are thick and may be difficult to cut.

Door and Window Sensors: Unscrew them and carefully pull them away from the door or window frame. Motion Detectors and Other Sensors: Disconnect the wiring.
The alarm in your home security system is designed to be a deterrent to intruders, as well as alert occupants and draw attention to your home, whether that be from neighbours, passers-by or authorities.
