## Abstract

An alert system configured to monitor a status of one or more supplemental door locks comprises a switch assembly and an alarm. The switch assembly is configured to detect whether one supplemental door lock is unlocked or locked and includes a switch, an indicator, and a communication element. The switch is to be coupled to a locking component of the supplemental door lock. The switch is configured to sense a position of the locking component and generate an electronic signal or data. The indicator is configured to provide a first indication of a status of the supplemental door lock. The communication element is configured to receive the electronic signal or data from the switch and generate a wireless signal that corresponds to the electronic signal or data. The alarm is configured to generate an audible or visible alarm when the switch assembly detects that the supplemental door lock is locked.

## Claims
