We present the first data release (DR1) of the Far-Infrared PolarimetricLarge Area CMZ Exploration (FIREPLACE) survey. The survey was taken using the214-micron band of the HAWC+ instrument with the SOFIA telescope (19.6$'$resolution; 0.7 pc). In this first data release we present dust polarizationobservations covering a ~0.5$\deg$ region of the Galactic Center's CentralMolecular Zone (CMZ), approximately centered on the Sgr B2 complex. We detect~25,000 Nyquist-sampled polarization pseudovectors, after applying the standardSOFIA cuts for minimum signal-to-noise in fractional polarization and totalintensity of 3 and 200, respectively. Analysis of the magnetic fieldorientation suggests a bimodal distribution in the field direction. Thisbimodal distribution shows enhancements in the distribution of field directionsfor orientations parallel and perpendicular to the Galactic plane, which issuggestive of a CMZ magnetic field configuration with polodial and torodialcomponents. Furthermore, a detailed analysis of individual clouds included inour survey (i.e., Sgr B2, Sgr B2-NW, Sgr B2-Halo, Sgr B1, and Clouds-E/F) showsthese clouds have fractional polarization values of 1--10% at 214-micron, withmost of the emission having values $<$5%. A few of these clouds (i.e., Sgr B2,Clouds-E/F) show relatively low fractional polarization values toward the coresof the cloud, with higher fractional polarization values toward the less denseperiphery. We also observe higher fractional polarization towards compact HIIregions which could indicate an enhancement in the grain alignment in the dustsurrounding these sources.
