- Start by determining the types of sensors you will need for your wireless security system. Certain types of sensors can detect a door or window opening. Glass breakage sensors are good for both windows and glass doors. Motion detectors can be added to your system easily, but must be calibrated for pets. Pressure sensors can be placed under carpets, near windows and doors; these are activated when someone steps on them. More exotic sensors include infrared detectors and laser sensors. In addition to sensors that detect intrusion, many wireless alarm systems include fire detectors.
- In most simple home alarm systems, the keypad functions also as the controller. If your system uses more than one keypad, one usually is set as the master controller, with the others used only to transmit unlock codes or arm the overall system. The master controller stores sensor location and information. Keypads should be placed near any frequently-used door. In homes where bedrooms are located on a different floor than the main entrances, consider installing a keypad near the bedrooms.
-
Alarms should be loud, and located where they can be heard throughout the home. In some homes, multiple alarms may provide better audio coverage than a single alarm siren.
If you spend a lot of time away from home, there are a number of companies that provide monitoring for self-installed alarms. A monitoring service generally will try to contact you before contacting police or fire officials. - In most cases each sensor will require a battery. Once the sensors are installed, they should be programmed into the appropriate section of the main keypad. Sub-keypad controllers and alarm sirens also must be programmed into the main system. Remember to check sensor batteries frequently to ensure the sensors are functioning properly.
