A device that controls the functions of an ALARM SYSTEM and can act as both an INPUT DEVICE and an OUTPUT DEVICE. The entry of a numeric code sequence will determine the response of the ALARM SYSTEM. It usually consists of a numeric keypad modelled after the standard telephone touchpad.
A panel usually made of metal or plastic with numbered push-button switches (like a touch-tone telephone) designed to provide access to certain types of control functions. Security, CD changers, and cellular systems represent typical examples.
a device which uses a numeric pad, similar to that of a telephone. The user simply presses his code into the keypad and the system reads the numbers. This system does not require the user to carry any special card or token but can be less secure since unless the user is very careful someone may see which numbers are being pressed. Certain keypads overcome this drawback by scrambling the number layout each time the keypad is used. Keypads can be used either by themselves or for high security in conjunction with some card reader technology. In this manner the user must both present a card and enter a code before access is granted.
The portion of the arming station containing numbered pushbuttons similar to those on telephones or calculators. These control the arming or disarming of the system. They may also perform other functions.
A device used alone, or in conjunction with a reader. Alone, it may be used in two ways: (a) to enter a PIN code to gain access through an access point (b) to enter a key code. A combined reader/keypad unit can be configured to only read an access card when a PIN code is entered. Close Glossary Window

A keypad is a set of buttons arranged in a block which usually bear digits and other symbols but not a complete set of alphabetical letters. If it mostly contains numbers then it can also be called a numeric keypad. Keypads are found on many alphanumeric keyboards and on other devices such as calculators, combination locks and telephones which require largely numeric input.
A type of controller used with X10 and other types of home automation systems. Keypads can be connected to your home wiring or use RF signalling. Some keypads can be programmed, whereas others provide simple on/off/dim commands. Lamp module: A type of home automation module that supports incandescent lighting, including dimming.
