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.
