DETECTOR AND BASE PLACEMENT Detector and base locations shall follow the drawings provided or approved by Siemens Industry, Inc. or its authorized distributors. This is extremely important! The detector placements shown on these drawings were chosen after a careful evaluation of all facets of the protected area. When drawings are not available, refer to Detector Placement section of detector Installation/Wiring Instructions and to NFPA 72, National Fire Alarm Code and CAN/ULC-S524.

DETECTOR MOUNTING USING THE DB2-HR BASE The detector is mounted on the DB2-HR base which attaches to a standard 4 inch square electrical box, with the box size and depth required by the NEC for the number and size of conductors used. Wire to the terminal blocks as shown in Figure 1. Wire size: max – 14 AWG, min – 18 AWG. 1. After all bases are installed, check wiring integrity. 2. To insure proper installation of the detector head into the base: a.
