Door entry security device with electronic lock

1. An alarm system comprising:

a. a door entry security device suitable for mounting on an entry door, said door entry security device comprising:

i. an electronic lock mechanism adapted to selectively lock and unlock an entry door on which the door entry security device is mounted, the electronic lock mechanism having a locked position or an unlocked position,

ii. a memory for storing the position of the electronic lock mechanism;

iii. a coded user input device reader for detecting a user input for locking or unlocking the entry door and generating an electronic lock command;

iv. processing circuitry adapted to receive the electronic lock command from the coded user input device reader, change the position of the electronic lock mechanism based on the position stored in the memory, and update the memory to the changed position of the electronic lock mechanism, and

v. a transmitter to transmit an electronic lock status message as a function of the updated position of the electronic lock mechanism stored in the memory, and

b. an alarm system control panel remotely located from said door entry security device and adapted to receive said electronic lock status message, to process said electronic lock status message to determine an alarm system function that should be performed, and to perform an alarm system function based on the electronic lock status message.

2. The system of claim 1 wherein said electronic lock status message is an unlock message and said alarm system function performed is disarming of the alarm system.

3. The system of claim 1 wherein said electronic lock status message is a lock message and said alarm system function performed is arming of the alarm system.

4. The system of claim 1 further comprising a door open sensor to sense if the entry door is open, wherein said electronic lock status message indicates if said entry door is open as indicated by the door open sensor and said alarm system function performed is to prevent arming of the alarm system when said entry door is open as indicated by the electronic lock status message.

5. The system of claim 1 wherein said door entry security device further comprises a receiver for receiving messages from the alarm system control panel.

6. The system of claim 1 wherein said electronic lock command is generated from mechanical interaction of a token with said coded user input device reader.

7. The system of claim 1 wherein said electronic lock command is generated from an electrical transmission to said coded user input device reader.

8. The system of claim 1 wherein said door entry security device further comprises a tamper detection device, and wherein said alarm system function performed is alarm notification when said tamper detection device determines the door entry security device has been tampered with.

9. A method of automatically controlling an alarm system, comprising the steps of:

a. storing a locked position or an unlocked position of an electronic lock mechanism in a memory of a door entry security device,

b. detecting a user input signal for locking or unlocking an entry door,

c. generating an electronic lock command from the user input signal,

d. changing the position of the electronic lock mechanism based on the position stored in the memory,

e. updating the memory to the changed position of the electronic lock mechanism,

f. transmitting from said door entry security device to a remotely located alarm system control panel an electronic lock status message as a function of the updated position of the electronic lock mechanism stored in the memory,

g. receiving said electronic lock status message by the remotely located alarm system control panel,

h. processing by the remotely located alarm system control panel said electronic lock status message to determine an alarm system function that should be performed, and

i. the remotely located alarm system control panel performing an alarm system function based on the electronic lock status message.

10. The method of claim 9 wherein said electronic lock status message is an unlock message and said alarm system function performed is disarming of the alarm system.

11. The method of claim 10 further comprising the step of the door entry security device executing an electronic lock function based on the user input signal.

12. The method of claim 9 wherein said electronic lock status message is a lock message and said alarm system function performed is arming of the alarm system.
