Johnson Controls SNC Series - User Manual

F4-SNC Installation Guide
Application
The Facility Explorer SNC Series (F4-SNC) are Ethernet-
based, supervisory controllers that connect Building
Automation System (BAS) networks to IP networks.
The SNC features onboard inputs and outputs for
direct control of equipment. This device monitors and
controls networks of field-level building automation
devices, including HVAC equipment, lighting, security,
and fire safety equipment. The SNC has FIPS 140-2 Level
1 Compliance, which is a United States government
cybersecurity standard that approves cyroptographic
modules/algorithms used for encryption.
The F4-SNC2515x-0x/x models have a total of 40 I/O points
- with 25 inputs and 15 outputs. The F4-SNC1612x-0x/x
models have a total of 28 I/O points - with 16 inputs and
12 outputs. The first two numbers of the product code
number represent the number of inputs (SNC2515x-0x/
x) and the next two numbers represent the number
of outputs (SNC2515x-0x/x). The SNC offers various
integration options.
Field Bus integrations supported
• BACnet MS/TP
Ethernet integrations supported
• BACnet/IP
• BACnet/SC
