Fire Alarm Systems | D9051 RS‑485 Bus Module
D9051 RS‑485 Bus Module ▶ Supports an RS‑485 circuit for up to 32 serial peripheral devices such as annunciators, controllers, and notification appliances ▶ Supports up to fifteen D9070/B Fire System Controllers or D9069A/B Fire System Annunciators ▶ Isolated data interface ▶ Supports data links to a master control panel or to a graphics driver ▶ Supports an output to network control panels
The D9051 is an RS‑485 network expander that provides an isolated data interface between a control module of the control panel and peripheral devices. It is powered by a control module of the D8024 or D10024A fire alarm control panels (FACPs). It has two connection points for two-wire RS485 peripheral communication circuits.
When connected to Port D of either FACP, it supports a peripheral circuit for D9069B Fire System Annunciators, D9070B Analog Fire System Controllers, four-way notification appliances such as synchronized notification appliances, and other serial peripherals. Note
Functions
Notification appliances on this circuit are powered by 24 VDC from the control panel or an approved 24 V auxiliary power source.
Port Assignments The output the D9051 can support depends on the port to which it is connected:

Mounting Considerations D8024
Technical Specifications
There are two connection ports on the D8024 FACP. The D9051 ribbon cable connects to the eight‑wire ribbon socket. D10024A There are three connection ports on the D10024A FACP. Depending on the circuit configurations, the D9051 can be mounted over a D9067 Circuit Module using stand‑offs at the four attachment points. The D9051 ribbon cable connects to the eight‑wire ribbon socket, and the D9067 to the ten‑wire ribbon socket. Wiring Considerations To FACP Plug the eight‑wire ribbon connector into the eight‑wire socket to connect the D9051 and the FACP control module. Network Circuit Wiring Serial network data communications occur using D9051 RS‑485 Bus Modules attached to Serial Port C on the FACP. The FACPs are wired in series to an NFPA Class B, Style 3.5 Signaling Line Circuit (SLC) on the appropriate RS‑485 bus. The RS‑485 terminals on the D9051 are polarity sensitive. The channels are marked A and B. Connect the data wires A to A and B to B. Cross-wiring between channels results in corrupted data, but does not damage equipment. To avoid data corruption, route cables so they do not run next to other cables.

Ordering Information D9051 RS‑485 Bus Module Provides an isolated data interface between a control module of the control panel and peripheral devices
Use shielded, 18 AWG (1.2 mm) twisted pair wire. The total length of the data cables between the two end control panels must not exceed 3935 ft (1200 m) per channel. For more information about control panel networking, consult the control panel’s installation guide and the D8024/D9024/D10024 Networking Guide (P/N: 34377). RS‑485 Circuit Wiring The two‑wire RS‑485 peripheral connects to the D9051 through the terminal block at the top of the module. Terminals are provided for two circuit connections. The circuit can be up to 4920 ft (1500 m) in length. Circuit wiring is 1.2 mm (18 AWG) shielded twisted pair cable.
