Security system and devices

A security system configured to operate in association with a facility, wherein the facility includes a plurality of rooms with corresponding doors providing access thereto, the security system comprising:

• one or more sensors linked to a communications network, each sensor configured to detect an object or event associated with a threat event, wherein the threat event is independent of user credential input, and further wherein the one or more sensors generate an output signal representing the detected threat event;
• a plurality of locking devices linked to the communications network, each locking device configured to selectively restrict movement of one of the corresponding doors, each locking device including an actuator and a local controller associated therewith, each local controller configured to:
• receive the output signal from the one or more sensors and process the received output signal to determine an actuator command;
• provide the actuator command to the actuator of the locking device;
• automatically actuate the corresponding lock actuator in response to the detected threat event;
• produce an actuator output based on the actuator command, the actuator output operable to manipulate the locking device between a locked configuration and an unlocked configuration, wherein in the locked configuration the locking device resists movement of the door;
• and
• propagate a control signal across the communications network to cause other local controllers to actuate respective lock actuators in coordination, thereby initiating a lockdown of the facility and the plurality of rooms in real time.
