Description
The Loop Interface LIF64-1 allows for the connection of
one ADM loop with bi-directional data exchange and up
to 128 detector zones to fi re detection control panels
Series BC216. The ADM loop supports 198 elements
(99 detectors and 99 modules) with System Sen-
sor/200 protocol or 126 elements (detectors and/or
modules) with Apollo/Discovery protocol.
Each ADM loop can be subdivided into a maximum of
128 detector zones. The function of the detector zone
(automatic fi re detector zone, technical message, fault
detection zone, etc.) as well as the element type (e.g.,
automatic detector, manual call point, monitor module,
control module or conventional zone module) can be
parameterised on the fi re detection control panel.
A two-sided isolator is integrated on the Loop Interface
(at the beginning and the end of the loop). The loop
wiring can be realized as ring, branch or any given com-
bination of sectional rings and branches.
Thanks to the ring-shaped cabling, all elements on the
loop remain functional in the event of a single wire brea-
kage. In addition, the wire breakage is displayed on the
control panel. What is more, the operational reliability of
those parts of the loop that are not affected is secured
in the event of a short circuit. Unshielded wires can be
used for the fi re detector cabling and, therefore, exis-
ting installations can be assumed smoothly and existing
cabling can be reused.
On the control panel, you can perform a maintenance
prognosis for each connected smoke detector. The
continuous monitoring of the detector function allows
for cost-optimized operation and optimum planning of
the maintenance works.
The Loop Interface provides a processor of its own. At
a possible central processing board failure, the diver-
sifi ed redundancy concept thus ensures reliable alarm
recognition.
