System Overview  
Installation/Configuration Notes  
The D326A Analog Point Contact Module allows compatible  
fire alarm control panels (FACP) to supervise Form A or B  
dry contact devices in a polling circuit. The D326A has an  
eight‑bit microprocessor and communicates with the  
control panel (both power and data) over a two-wire polling  
circuit. The initiating device circuit (NFPA Style B)  
connected to the D326A can have up to 20 normally-open  
(NO) dry contact devices. Each module can monitor one  
normally-closed (NC) device (NC devices must be non-alarm  
applications).
