C.3. D9051 RS 485 Bus Module
The D9051 module is an RS 485 Network Expander. It provides an isolated Class B, Style 4 or
Class A, Style 6 data interface between the Control Module and Command Centers, Annunciators,
networked panels, serial peripherals, and computer graphics systems.
The D9024 and D10024 Fire Alarm Control Panels can support up to 31 peripheral communications
devices on the RS485 bus. Each device must be assigned an individual binary address.
Port D
supports a peripheral circuit for D9069 remote annunciators, D9070 controllers, 4-way
notification appliances, synchronized notification appliances, and other serial peripherals.
Port C
supports an RS 485 panel-to-master data link, or panel-to-graphics data link.
Port B
supports an RS 485 output to network panels.
Remove AC power from the system at the dedicated 120
V
AC breaker, “lock out” the breaker, and
remove the standby battery power before making or breaking any connections to the FACP.
Caution: Inform the operator and the local authority before installing this module in an existing
system. Disconnect all power to the Fire Alarm Control Panel before installing this
module.
