VESDA Interface
The VESDA Air Sampling interface connects to the
MOM-4/2, TB3 or TB4, terminals 12-16, depending on
where the NIM-1W is installed (Refer to Figure 8). Up
to 31 Air Sampling detectors can be connected to a
single NIM-1W.
The VESDA/MXL-IQ Intelligent Interface requires a
model CPY-HLI which consists of an MXL-IQ/VESDA
High Level Interface and a VESDAnet Socket. The
CPY-HLI can support up to 31 VESDA detectors
utilizing a VESDA network. Refer to the
CPY-HLI
Installation Instructions,
P/N 315-099200, for mount-
ing and installation of the CPY-HLI to the VESDA
detectors.
Complete wiring of the Intelligent Interface as shown
in Figure 8.
• Place the end-of-line resistors in the locations
specified in Figure 8.
• Install the 5 leads of the Model CPY-HLICABLE
interface cable (P/N 500-699911) to the MOM-4/2
according to the
CPY-HLI Installation Instructions,
P/N 315-099200. (Refer to Figure 8.)
• To connect the CPY-HLI to the VESDA network,
refer to the
CPY-HLI Installation Instructions,
P/N
315-099200.
NOTE: VESDA is supported in NIM-1W firmware
version 2.0 and higher, SMB ROM version 6.10 and
higher and CSG-M version 11.01 and higher.
