DNP-R-2F/FC-K
Unit specific description
Signal propagation delay and jitter
Many CIE (e.g. Fire panel) only offer tight timing requirements for supporting a class A
redundant ring application. With the introduction of third-party equipment into an OEM
redundant transmission path, additional signal delays and jitter are often introduced
with the original CIEs no longer able to function as required. The DNP R-2F/FC
modules are designed to support extended signal delays and jitter. When used with the
installed CIEs, these modules can provide a functional class A redundant solution that
is tolerant of most delays and jitter.
The LED indicators show the status of the data signals. The optic fibre module
provides a “signal detect”
function that monitors the link connection dynamically,
ensuring that the signal level at the receiver is within the required specification for good
communication. These signals are monitored and recorded to track transmission path
performance drift.
Configuration and Installation
The
DNP R-2F/FC
modules only support passive mode routing.
All communication settings are configured using the rotary switch. Set for the
respective fire alarm panel by setting the Rotary switch 1 in Table 10.
