Data entry keypad assembly
First Claim
1. A data entry keypad assembly for a system controlling a plurality of components, for entering numeric data and for displaying information about a state of said components, the keypad assembly comprising:
- a keypad panel having a plurality of key zones arranged in a ordered matrix and each having a numeric component label identifier associated with one of said components;
a key switch mounted to said panel in each of said zones;
a light source means provided in each one of said key zones;
input controller means connected to said key switches for collecting, in a first state, numeric data in the form of a sequence by key presses of said switches provided in said key zones, and for changing, in a second state, a state of one of said components associated with said key zone in which said one key switch is located by pressing said one key switch, andstate information displaying means connected to said light source means for indicating a state of each individual one of said components each associated with said label identifiers by controlling an illumination state of each individual one of said light source means.

Abstract
A data entry keypad assembly is provided for a system controlling a plurality of components. The keypad assembly includes a plurality of key zones arranged in an ordered matrix and each having a label identifier, and a plurality of key switches, provided in corresponding key zones. The keypad assembly also includes a plurality of light source means, each one of the light source means also provided in the corresponding key zones. Input controller connected to the key switches is provided for receiving data in the form of a sequence of key presses of the switches, and information displaying controller connected to the light indicator is provided for indicating a state of some of the components each associated with some of the label identifiers. When the data entry keypad assembly is used for a security system, it controls a plurality of detectors and warning devices, and displays a detection state of the detectors, while allowing activating/deactivating commands to be entered.

17. A keypad assembly for a security system, said system having a plurality of numbered security zones or detectors, comprising:
-
a keypad panel having an array of numbered keys; a key switch associated with each of said numbered keys; means for selectively and separately illuminating each key; and control circuitry connected to said key switches for obtaining, in a first mode of operation, numeric data from key presses of said keys, and, in a second mode of operation, for accepting a key press of one of said keys as a command to change the state of the detector or security zone corresponding to the key pressed, and for activating said illumination means to selectively illuminate each key having a number corresponding to a detector or security zone whose state is to be indicated by said illumination, whereby said keypad assembly is capable of accepting commands and simultaneously displaying the states of plural security zones or detectors.
