Do-It-Yourself Wireless Alarms

Hardwired alarm systems may be popular, but installing wireless alarms is much more convenient as this task doesn’t require any professional skill or expertise.

Standard wireless alarms consists of a sensor, which is designed to detect someone entering the home by a window or door and the signal of the sensor is sent via the transmitter to a receiver, which eventually sounds off an alarm. It is possible for individuals to make this particular alarm by themselves with the help of a wireless doorbell that can fulfill this task efficiently. Only a few tools are required for this task, which are usually present around the house and the procedure itself is quite straightforward. The wireless doorbell may have to be disassembled partially in order to make it into wireless alarms.

How to Begin:

The wireless doorbell receiver should be turned until the back is facing you. The battery compartment that’s present on the back of the wireless doorbell receiver should be opened. If the lid is attached by a screw, the screw should be loosened with the help of a screwdriver. The correct number of the required batteries should be inserted into the battery compartment. The lid should then be closed and the lid should be tightened as well. The wireless doorbell receiver should be placed on a table that’s near your bed. It can also be mounted on a wall near the bed with the help of wood screws. Once this is done, the switch that’s present on the side of the receiver should be turned on.

Second Stage:

The two screws on the remote doorbell module should be loosened with your fingers. Use a wire stripper for stripping ½ inch of insulation from the ends of the two wires that are attached to the hobby wireless alarm bell. Each wire should be winded around one of the screws and they should then be tightened with fingers. The remote doorbell module should be turned over until the back is facing you. The lid of the battery compartment on the back should be opened and the screws should be loosened. A utility knife should be used to cut 10-inch lengths of electric wire from the spool. Take a wire stripper for stripping ½ inch of insulation from the end of both wires.

Final Steps:

A soldering iron should be heated for about five minutes. An end of each wire should be soldered to one of the two contacts found within the battery compartment. The solder should be allowed to cool for two minutes. The button on the module should be taped in with some duct tape. The module and the doorbell should be placed against the wall and near the door frame. Use a scissor for cutting 2-by-2 inch squares from the foil. The free ends of the two wires should be soldered to the edge of a foil square. The soldering iron should be unplugged.

Finishing Touches:

One side of the foil squares should be applied with glue. This square should be placed opposite the door frame and against the bottom edge of door. The foil should be pressed to the door and allowed to glue. The other foil square should be placed against the edge of the door frame and bend it slightly. Now, your DIY wireless alarms will sound from the alarm bell and the receiver if the door is opened.
