INSTALLATION INSTRUCTIONS 

NOTIFICATION APPLIANCE CIRCUIT INTERFACE MODULE 

(NACIM) 

 

Use this product according to this instruction manual.  Please keep this instruction manual for future reference. 

 
 

GENERAL: 

The Notification Appliance Circuit Interface Module (NACIM) is used to convert the Notification Appliance Circuit (NAC) of the 
Fire Alarm Control Panel (FACP) to an open collector circuit to operate the inputs of the Single Circuit SAFEPATH, the Digital 
Voice (DV) Digital Voice Expansion Module (DV-EM) and multi circuit SAFEPATH units.  Figure 1 shows a NACIM wired in a 
Single Circuit SAFEPATH application.  Figure 2 shows a NACIM wired in a DV or multi circuit SAFEPATH application with a 
single NAC.   Figure 3 shows multiple NACIM’s in a DV or multi circuit SAFEPATH application with multiple NAC’s.  (The 
NACIM can be connected to either a 12 Volt or a 24 Volt NAC.  An End of Line Resistor (EOLR) that is listed for use with the 
FACP, must be installed across the two terminals of the TB2 on the NACIM.)
