DG-1 TCM is a microprocessor-based detector of narcotic gases (e.g. trichloromethane vapours). It is recommended that you install it in bedrooms, security offices and other high risk areas likely to be targeted by intruders. Due to the nature of narcotic gases, which are heavier than air, the detector should be installed low, just above the floor of the supervised room.
