Profile: Concept Smoke Screen Ltd. offers security smoke systems. Smoke screen evolution series is a smoke generator which includes a precision engineered heater block & twin and cartridge heaters. The installation of our generator is simple with options for over wall mounting or covert ceiling mounting. Smoke screen sound barriers are used with security smoke generators. Upon activation, an intolerable wall of sound is created forcing any intruder to leave the area. The design of the S3B allows it to be unobtrusively installed in even the most contemporary of environments.
