a plurality of dedicated alert buttons installed to an interior of the building; a door lock installed to at least one of a plurality of rooms of the building; a control panel installed to at least one of a plurality of rooms of the building; wherein the control panel is electronically linked to a computer programmed to prompt displays on a display screen of the control panel, and further wherein the plurality of dedicated alert buttons and the door lock are electronically linked to the computer; wherein the control panel further includes a switch module including a plurality of control panel buttons each corresponding to a designated event, and further wherein the computer is programmed to initiate a performance of one of a plurality of predetermined response routines in response actuation of a corresponding one of the control panel buttons or one of the plurality of dedicated alert buttons, and further wherein the computer is programmed to selectively establish a live communications link with a first responder organization, wherein the predetermine response routines include: activate the dye spray system to allow a user to prompt dispensing of a dye at a location of the vestibule where the active shooter is likely located, automatically activate the door lock to effectuate a lock down of each of the at least one of the plurality of rooms in response to the actuation, a camera installed to the interior of the building sending a live feed to the display screen; and a threshold protection device that includes a protection arrangement with ballistic panels installed to at least one interior room of the building to form a safe zone which protects occupants of the at least one interior room. ### Claim 2 (depends on 1) The security system of claim 1, wherein the dye spray device include a nozzle, and further wherein the dye spray device is installed such that the nozzle is aimed at an interior of the vestibule. ### Claim 3 (depends on 2) The security system of claim 2, wherein the dye spray device includes a supply of dye fluidly connected to the nozzle and a control mechanism configured to release dye from the supply to the nozzle, and further wherein the dye spray system further includes an actuator electronically linked to the control mechanism for prompting operation of the control mechanism. ### Claim 4 (depends on 3) The security system of claim 3, wherein the actuator is located outside of the vestibule. ### Claim 5 (depends on 4) The security system of claim 4, wherein the actuator is electronically linked to the computer, and further wherein the computer is programmed to operate the actuator in one of: an active state in which the actuator is permitted to signal the control mechanism to release dye from the supply when actuated by a user; and an inactive state in which the actuator is prevented from signaling the control mechanism to release dye from the supply when actuated by a user. ### Claim 6 (depends on 5) The security system of claim 5, wherein the computer is programmed to normally operate in the inactive state. ### Claim 7 (depends on 6) The security system of claim 6, wherein the computer is programmed to transition to the active state only upon the occurrence of a pre-determined event. ### Claim 8 (depends on 1) The security system of claim 1, wherein the control panel is electronically linked to the dye spray system. ### Claim 9 (depends on 1) The security system of claim 1, wherein the predetermined response routines include active shooter event, soft lockdown medical, soft lockdown disorderly, evacuation, and weather alert. ### Claim 10 (depends on 1) The security system of claim 1, wherein the door lock is a first door lock installed to a first room, the system further comprising a second door lock installed to a second room of the building and electronically linked to the computer, and further wherein the computer is programmed control operation of the first door lock independent of the second door lock. ### Claim 11 (depends on 1) The security system of claim 1, wherein the computer is programmed to record a date, time and location of the dedicated alert button in response to actuation of the dedicated alert button.
