The 4098-9788 base is designed to be used with 4098 Series smoke and heat detectors, as well as 
the QuickConnect2 photo sensor.  To use a 4-wire configuration, you must use the 4098-9682 
relay base.  Heat detectors require the 4098-9684 base when used with a remote LED.  This 
section only covers the information necessary to mount and wire these base configurations.  
Before installing these bases, make a survey of the area to be covered in accordance with 
information provided in NFPA 72.  For additional information, refer to the NEMA Guide for 
Proper Use of System Smoke Detectors. 
 
CAUTION:  Install the bases in this section in accordance with applicable NFPA 
standards, local codes, and Authorities Having Jurisdiction (AHJs).  
Failure to follow these instructions may result in failure of the detector 
to initiate an alarm condition.  The manufacturer is not responsible for 
detectors that have been improperly installed, tested, or maintained.
