System and method for monitoring and securing a supervised opening

摘要

A method of securing an access point comprises transitioning to a first alarm state in response to: receiving an indication that the access point is open, sounding a first audible alarm in response to the open access point, silencing the first audible alarm and returning to the armed state in response to a disarming action by a user, transitioning to a first disarmed state in response to receiving an indication of the disarming action by the user, initiating a countdown from a first predetermined time period in response to the disarming action by the user, returning to the armed state upon the expiration of the first predetermined time period, transitioning to a second disarmed state in response to receiving an indication of a closed access point, and initiating a countdown from a second predetermined time period in response to a remaining first predetermined time period being greater than the second predetermined time period.

1. A method of monitoring and securing an access point, comprising:
being in an armed state; transitioning to a first alarm state in response to receiving an indication that the access point is open, wherein the first alarm state includes:
sounding a first audible alarm in response to the open access point;silencing the first audible alarm and returning to the armed state in response to a disarming action by a user; transitioning to a second alarm state in response to receiving an indication of a power outage, wherein the second alarm state includes:
switching to a backup power supply;sounding a second audible alarm in response to the power outage; andsilencing the second audible alarm and returning to the armed state in response to a resumption of power; transitioning to a first disarmed state in response to receiving an indication of the disarming action by the user, wherein the first disarmed state includes:
initiating a countdown from a first predetermined time period in response to the disarming action by the user;returning to the armed state upon the expiration of the first predetermined time period; andrestarting the countdown from the first predetermined time period in response to a repeating disarming action by the user; and transitioning to a second disarmed state in response to receiving an indication that the access point is closed, wherein the second disarmed state includes:
initiating a countdown from a second predetermined time period in response to a remaining first predetermined time period being greater than the second predetermined time period and transitioning back to the armed state upon expiration of the second predetermined time period;continuing to countdown from the first predetermined time period and transitioning back to the armed state upon the expiration of the first predetermined time period in response to the first predetermined time period less than or equal to the second predetermined time period.
