by Industry Inc or its authorized distributors This is extremely important The placements shown on these drawings were chosen after a careful evalua of all facets of the protected area When drawings are not available refer to Placement section of detector Installation Wiring Instructions and to NFPA National Fire Alarm Code and CAN ULC S524 Model DB2 HR from Siemens Industry Inc is a polarity insensitive detector base is compatible with the detectors listed in Table 1 base should be interconnected as shown in Figure 1 and wired to the device loop of control panel Line 1 and Line 2 can be either line of the loop Note any limitations on the of detectors and restrictions on the use of remote devices permitted for each For maximum number of devices refer to the panel power calculations in the manual P N 315 033060 wire size AWG minimum AWG maximum larger than 14 AWG can damage the connector Industry Inc Infrastructure LIMITED WIRING compliance with NEC Article 760 all power limited fire protective signaling conductors must separated a minimum of 1 4 inch from all of the following items located within an outlet box light 1 or non power limited fire protective signaling conductors meet the above the requirements the following guidelines must be observed when this relay base module BARRIER Module Barrier must be used when the DB2 HR relay contacts are connected to non power lines Break apart the barrier to the correct size and shape shown in Figure 2 for the 4 inch box Install the barrier diagonally into the back box to create two separate compartments the backbox to separate the wires as shown in Figure 2 SQUARE BOX 1 8 INCHES DEEP 6 OFF THIS WHEN A 4 INCH BOX 2 the Control Module Barrier ENTERING OUTLET BOX Limited Wiring power limited wiring must enter the outlet box separately from the electric light power Class or non powered limited fire protection signaling conductors For the DB2 HR wiring to terminal TB3 and TB4 must enter the outlet box separately from wiring to terminal block TB1 IMPORTTTTTANANANANANTTTTT Minimize the length of wire entering the outlet box IMPOR IMPOR IMPOR IMPOR Industry Inc Infrastructure MOUNTING USING THE DB2 HR BASE detector is mounted on the DB2 HR base which attaches to a standard 4 inch square box with the box size and depth required by the NEC for the number and size of used Wire to the terminal blocks as shown in Figure 1 Wire size max 14 AWG 18 AWG After all bases are installed check wiring integrity To insure proper installation of the detector head into the base sure that existing wires are away from connector terminals that screw terminals are tight LED WITH BASE FOR O N O T P A I N T COVERS 3 the Detector into the DB2 HR Base Industry Inc Infrastructure SECURITY DISCLAIMER provides a portfolio of products solutions systems and that includes security functions that support the secure of plants systems machines and networks In the field of Technologies this includes building
