In a single box we will be able to connect 2 loop controllers and their 4 corresponding loop drivers.
Therefore for configurations in excess of 8 loops we will need two boxes.

1.5. – Loop Elements Capacity
The number of devices that it is possible to connect to the loop is calculated by the software of loop
elements capacity calculation.
In this software must be entered the information of the control panel model, wire length (m), cable section
(mm2), arrangement of elements in the wire and number of devices of each type connected in that loop.
The arrangement of elements in the wire option has
two possibilities
;
"
Distributed
" refers to the fact that the elements are distributed along the cable that is in a closed loop. It
offers a fast and transparent way to calculate general closed-loop operating situations;
"
Point
" refers to the calculation in open line with all the elements located at the end of the cable length
defined in the program. It allows calculation of complex element distribution situations or open-line
operation.
The software returns the electrical load of the sysrem in % , number of equivalent elements and relays in
the loop. It must not be exceed the limits establieshed in the Maximum devices per control panel table
(loop limits and control panel limits).
INSTALLATION EXAMPLE
An installation requires 136 A30XHAS sensors, 10 PUCAY manual call points and 18 addressable
sounders SIRAY with standard sound level. These elements are distributed over a 500 m long copper cable
with a 2x1.5 mm2 section in a closed loop over the central unit.
This information is entered into the loop element capacity calculation software as indicated in the attached
figure.
The software returns the following information about the calculated loop:
- Loop load in %. Do not exceed 100% capacity. An adequate design should contemplate a certain
margin to the maximum capacity (for example 10%).
- Number of elements: allows checking that the maximum capacity of elements in the loop is not
exceeded (226 in Lyon and Zafir control panels, 99 in C-Lyon).
- Number of relays: allows to check that the maximum capacity of relays per loop is not exceeded
(32 in Lyon and Zafir control panels, 16 in C-Lyon)
NOTA*: For the LYON control panel, do not exceed the limit of 199 relays per control panel.
