The user interface

Lew Stouffer - Tuesday, March 18, 2014

The keypad is the standard user interface for your security system. It allows you to turn the system on and off as well as giving you access to system controls, such as assigning new user codes. Every system needs one. They come in many different variations.

LED or Icon displays are the lower end of the keypads available. Typically they display system information by lighting a led light or an icon that the user then needs to interpret. For instance, the “number 1” will illuminate to show that zone 1 is open.


Fixed displays are the most common these days. They display the system information from a fixed selection of words and numbers on an LCD screen. Zone violations are typically displayed as a number. These keypads do require a little interpretation on the part of the user.


The next step up in usability and price would be Custom displays. These keypads display the system information using a customizable list of words and numbers. For example, instead of the keypad displaying a “1” to mean that zone 1 is open, it would display “front door”. Many of the security systems higher functions require this type of keypad for them to be displayed. These keypads are typically a little more user friendly because of the way they display the information.

Touchscreen keypads have been available for several years now. They offer the flexibility of the custom keypad with a much cleaner look. Many of these kind of keypads offer the ability to act as an electronic picture frame as well. There is a pretty steep price climb to this keypad though. Touchscreens also allow some aspects of home automation to be utilized through one device.

How many keypads are needed? Generally speaking, it is best to have a system control on each floor of the premises. This allows for the most flexibility when using your security system. A typical installation would have one within reach of the entry door(s) and one in the master bedroom. Which leads us to the other forms of system controls available.

Key fobs are an inexpensive convenience item that can expand the usability of your security system considerably. They key fob is a small remote control for your security system that is limited to about a 50 feet range. It can be put on your keychain and used much like your cars remote fob. They typically have several buttons (we only install 4 button key fobs) Armed Away, Armed Stay, Disarm and a police Panic button. An interesting use that a customer of ours uses their key fob for is to allow the cleaning crew access to their home without giving them a code. They have a prearranged location to leave the key fob on cleaning day. On days the cleaning crew is not to have access to the home the key fob is moved from that location. Simple but effective.

Another control that is gaining in popularity is the smartphone app. It gives the convenience of the key fob, minus the Panic button. It also allows the user to see the systems event history. For instance, if you are at work you can see what time you kids get home from school. Smart phone apps also allow the user access through a standard web browser.
