Fire Alarm Systems | D326A Analog Point Contact Module
The D326A Analog Point Contact Module provides a variety
of fire alarm functions, such as monitoring manual pull
stations, waterflow devices, or other dry contact fire alarm
activation applications. The module allows for alarm,
trouble, and supervisory conditions. The D326A module
mounts on a plate that attaches directly to a UL‑Listed four-
inch square back box having a minimum depth of 2-1/8
inches. A cover plate leaves the status LED visible.

System Overview
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).
