D328A Analog Relay Module
www.boschsecurity.com
The D328A is used to connect a fire alarm control
panel (FACP) to other systems, controller inputs, door
closures, fan controls, annunciators, indicators or
other dry contact input devices. Normally-open (NO)
or normally-closed (NC) contacts can indicate alarm,
supervisory or trouble conditions.

Functions
Basic Operation
At a single address point on the FACP's polling circuit,
this module provides a connection point for auxiliary
system controls such as elevator recall systems or
HVAC shutdown.
Installation/configuration notes
Status LED
An LED confirms polling response and activation
status. The LED flashes green to indicate a normal
polling response and flashes red to indicate activation.

Notice
The FACP's EPROM must be version 6.64 or
higher.
Installation Considerations
There are three steps to installing the NAC module:
1.
2.
3.
Set the point address: Use the D5070 Analog Device
Programmer to set the address by programming an
EEPROM microchip.
Connect the wiring: Wiring terminals are clearly
marked and the module leaves ample room in the
back box for wiring.
Mount the module in the back box: The relay module
mounts on a four-inch square back box. A wall plate
(supplied) covers the module concealing the address
pins but leaving the LED visible.
Data Circuit Length
Data (or polling) circuit length is the distance over the
circuit wire from the connection at the D9067 module
to the most distant device and back to the D9067
module. The screw terminals can accept up to 14 AWG
(ISO 2.5 mm2) wire, but this reduces the allowable
length of the circuit. For specific wire instructions and
specifications, see the D9067 Installation Guide.
Data wire must be shielded cable.
