<p>A security system is for monitoring a door movably disposed within a frame. A lock is adjustable between a locked configuration and an unlocked configuration and a lock sensor is configured to generate a signal when the lock adjusts to the unlocked configuration. A door sensor is configured to generate a signal when the door displaces with respect to the frame and an alarm device is configured to provide an alarm. Further, a control is coupleable with the lock and door sensors and is switchable between armed and disarmed modes. The control is configured to operate in the armed mode such that the control activates the alarm when the control receives the door sensor signal prior to a receipt of the lock sensor signal. Alternatively, the control switches to the disarmed mode when the control receives the lock sensor signal prior to a receipt of the door sensor signal.</p> |
