Abstract: Some embodiments are directed to a lockdown apparatus for facilitating initiation of lockdown procedures at a facility that includes multiple doors and is configured for occupation by facility occupants. A lockdown actuator is disposed at the facility and configured to initiate transmission of a lockdown initiation signal upon being actuated, the lockdown actuator being configured to be recognizably distinguishable from the fire alarm actuator. A lockdown communicator is configured to produce a lockdown initiation communication for communicating initiation of lockdown procedures to the facility occupants and individuals not disposed proximate the facility upon transmission of the lockdown initiation signal, the lockdown initiation communication being recognizably distinguishable from the fire alarm communication.

Abstract: Some embodiments are directed to a lockdown apparatus for facilitating initiation of lockdown procedures at a facility. The lockdown apparatus can include a combined actuator and image sensor assembly disposed at the facility that is configured to be recognizably distinguishable from a fire alarm actuator. The assembly can include a lockdown actuator configured to transmit a lockdown initiation signal upon being actuated, and an image sensor configured to capture at least one of a still image an a video image of a region proximate the assembly. The lockdown apparatus can also include a lockdown communicator configured to produce a lockdown initiation communication for communication initiation of lockdown procedures to the facility occupants and individuals not disposed proximate the facility upon transmission of the lockdown initiation signal, the lockdown initiation communication being recognizably distinguishable from a fire alarm communication.
