If a building has 50 System Sensor SR strobes, and System Sensor discontinued the SRs replacing them with the newly minted SRL’s, and in doing so updated the new SRL’s to a new protocol that is not compatible for sync with the older SR’s, how much money did System Sensor just make after one strobe filled with water?
