How Wireless Fobs Allow Communication Between Different Technology

In a continually advancing wireless world, electronic users require more and more remote features to help with everyday tasks

. Wireless key fobs can add worth and convenience to any security system. Wireless remotes allow management control over their home alarm systems, as well as portable personal protection. Users can arm and disarm the system without difficulty as they approach their house or, through the panic button, call for help from anywhere close by, or inside the home.

Full wireless operation has two requirements: a radio transmitter, with which to send signals, and a wireless receiver to receive those signals, translate them, and internally relay them to the alarm system control panel. Your wireless alarm setup will include either a stand-alone receiver or a receiver integrated into a keypad.

For the most part, a LED found between or on the buttons will light up, indicating a signal has been sent to the control panel receiver. Some even include displays with updated responses from the control panel. A typical function of key fobs is 'Away Arming', by which both the interior and exterior zones will be armed, allowing you to exit the premises. Another feature is 'Disarm', which allows the user to disarm the system without entering an access code. The 'Panic' function usually must be pressed for three seconds for it to notify the central monitoring station of a situation requiring the police. Obviously you will need a monitored account already activated for this function to work.

Newer models enable communication from the key fob to the panel and vice-versa. These newer options, featuring icon displays and built-in buzzers, have both visual and audible indications of the system's status. Most wireless key fobs have more than just one function, and normally consist of 3 functions, a panic remote that can be used to arm and disarm, as well as a variety of other remote functions. Wireless key remotes like the new DSC WT4989 have up to five buttons, a system status button, as well as four additional programmable buttons with six available function choices. Programming for some additional functions can include door openers for the garage, indoor/outdoor light operation, or powered gate access. The only requirement is that the key is within the range of the wireless receiver or else signals will not be received.

Newer key fobs sometimes include backlit icon displays, and built-in buzzers for audible feedback. Three years of battery life and LED flashlights are currently among the most popular common features. To reduce false alarms, there is usually a 3-second delay on panic functions. Check with your alarm dealer to add wireless key fobs to your systems, or to get them included in your new home security package. Key fobs can bring a little more peace of mind around the home and allow the user to arm/disarm the system with the touch of a button.
