Install the relay module using the following steps: 
 
1.  Mount a 1-1/2 inch (3.81 cm) extension ring (not supplied) to an octagonal or square 
electrical box (not supplied).  The extension ring is required to meet the minimum box 
volume requirement (32.3 cu. inch/529.4 cu. cm) for relay module installation. 
 
2.  Mount relay module inside extension ring directly behind base and sensor.  Do not mount 
remotely.  See Figure 4-1 or 4-2 for relay module connections. 
 
Note:  Use the exact configuration of electrical box (square or octagonal) with extension to 
mount sensor base when installing the relay module.
