Door security device for use in security systems
First Claim
1. A method of operating a security system comprising an entry door and a lock for selectively locking and unlocking the entry door, comprising the steps of:
- sensing the position of the lock as being locked or unlocked;
detecting the position of the door as being open or closed;
generating a door status signal that indicates whether the door has been detected as being opened or closed; and
generating a security system disarm signal when(i) the position of the lock is sensed to have transitioned from a locked state to an unlocked state,(ii) the door status signal indicates that the door is closed at the time that a predefined time period has elapsed since the position of the lock is sensed to have transitioned from a locked state to an unlocked state; and
(iii) the door status signal indicates that the door has been opened after the predefined time period has elapsed.

Abstract
A door entry security device used in a security system including a control panel, the door security device in a housing suitable for mounting within a recess of a doorjamb or door of a premises. In the housing is a lock position detecting switch, adapted to detect the position of a lock mounted on a door as being either locked or unlocked, a door position detecting switch adapted to detect the position of the door as being either open or closed, and processing circuitry adapted to generate a security system disarm signal when (1) the position of the lock has transitioned from a locked state to an unlocked state, (2) the door is closed at the time that a predefined time period has elapsed since the position of the lock transitions from a locked state to an unlocked state, and (3) the door has been opened after that predefined time period has elapsed. The door entry device also has a data transmitter for sending the security system disarm signal to the control panel. An alarm signal is generated and transmitted to the control panel when the door is open at the time that the predefined time period has elapsed since the lock has transitioned to an unlocked state. The control panel prevents the security system from being disarmed when an alarm signal is received unless a user code is entered into the security system.

13. A door entry security device comprising:
-
a housing; a lock position detecting switch within the housing, adapted to detect the position of a lock mounted on a door associated with a doorjamb as being either locked or unlocked with respect to the doorjamb; a door position detecting switch within the housing, adapted to detect the position of the door as being either open or closed with respect to the doorjamb and to generate a door status signal that indicates whether the door has been detected as being open or closed; processing circuitry adapted to generate a security system disarm signal when the lock position detecting switch indicates that the position of the lock has transitioned from a locked state to an unlocked state, the door status signal indicates that the door is closed at the time that a predefined time period has elapsed since the position of the lock is sensed to have transitioned from a locked state to an unlocked state; and the door status signal indicates that the door has been opened after the predefined time period has elapsed. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A security system comprising:
-
a control panel, and a door entry security device comprising; a housing; a lock position detecting switch within the housing, adapted to detect the position of a lock mounted on a door associated with a doorjamb as being either locked or unlocked with respect to the doorjamb; a door position detecting switch within the housing, adapted to detect the position of the door as being either open or closed with respect to the doorjamb and to generate a door status signal that indicates whether the door has been detected as being open or closed; processing circuitry adapted to generate a security system disarm signal when the lock position detecting switch indicates that the position of the lock has transitioned from a locked state to an unlocked state, the door status signal indicates that the door is closed at the time that a predefined time period has elapsed since the position of the lock is sensed to have transitioned from a locked state to an unlocked state; and the door status signal indicates that the door has been opened after the predefined time period has elapsed; and a data transmitter for sending the security system disarm signal to the control panel. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A security system for a premises comprising an entry door and a lock for selectively locking and unlocking the entry door, comprising:
-
means for sensing the position of the lock as being locked or unlocked; means for detecting the position of the door as being open or closed; means for generating a door status signal that indicates whether the door has been detected as being opened or closed; and means for generating a security system disarm signal when (iv) the position of the lock is sensed to have transitioned from a locked state to an unlocked state, (v) the door status signal indicates that the door is closed at the time that a predefined time period has elapsed since the position of the lock is sensed to have transitioned from a locked state to an unlocked state; and (vi) the door status signal indicates that the door has been opened after the predefined time period has elapsed. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48)
