Abstract
Examples provide a siren device having a plurality of lockable functions, such as amplifier strength and siren tone functions. At production, one or more of the available functions are placed in a locked state in which the locked function is inoperable. One or more of the functions may be initially unlocked at manufacture or purchase. The user can obtain an unlock code to unlock one or more of the functions, if desired, after purchase. Thus, if a user wants to increase the amplifier strength from one-hundred watts to two-hundred watts, the user can obtain one or more unlock codes to unlock that selected function for a licensed time-period. When unlocked, the selected function operates normally. A data storage device on the multifunction siren device stores an assigned UID, a set of available lockable functions, and a lock status of each function in the set of available functions.
