The DB702 is a conventional fire detector base used for all 700 series conventional fire
detectors. It includes a normally closed continuity switch to allow for easy cable testing
during installation. Inserting a detector into the base opens the continuity switch in the
base to allow for standard open circuit monitoring. A locking mechanism implementation in
conjunction with the detector allows for the detector to be safeguarded against unauthorized
removal. Insert detectors without using forceOne way only fitLocking mechanism provided
