Siemens FDB201-AA Conventional Detector Socket (with DBZ1190-AA Micro Terminal)

FDB201-AA is the 100 mm diameter socket on Siemens collective fire detection lines that carries point-type detectors; it has the same body as FDB201, with the difference being that one DBZ1190-AA micro terminal comes pre-installed in the box. This micro terminal enables the termination of thin conductors with 0.28-0.5 mm² cross-section on the line, while the socket's own spring-loaded terminals work with 0.2-1.5 mm² cross-section. The gray color of the terminals indicates that the socket belongs to a collective line; for addressable lines, the sister model FDB221 with orange terminals is used. In mounting, the adjustable hole spacing between 46-79 mm accommodates common box dimensions; the socket height is 22 mm, and with the detector mounted, the total height is 54 mm, and the white (approximately RAL 9010) body is compatible with most ceiling coverings. Values such as operating voltage, IP class, and temperature range depend not on the socket but on the detector mounted on top; order number A5Q00012742, weight 0.029 kg.
