The SND monitored output (sounders) is dedicated to the connection of conventional sounders. The maximum number of
sounders connected to the output must not exceed a current of 1A.
Note: The SND output is enabled if there is a “Loop sirens active” event.
Note: If the sounders are set to “Flash only” it is not considered a Loop sirens active event. The SND output is not
enabled.
N.B.: Press the “Silence Sounder” button to disable the SND output.
Connection example for an indication device, connected to the SND output.
3.6 Loop Controller
Panel 41CPE118 communicates with Loop Controllers (41ECL120) using Comelit communication protocol.
Connection of Loop boards takes place via a “comb” terminal, where the first board (supplied by default inside the panel) is
connected to the output module.
The Loop expansion has 2 main functions:
1. It collects data from the devices connected to the communication line and transmits this data to the output module.
2. It receives commands from the output module and transmits them to the devices connected to the communication line.
Up to 250 devices can be connected to each Loop controller 41ECL120.
The maximum absorption of the devices on each Loop board should not exceed Imax = 700 mA.
If consumption exceeds this value, an overload protection will be triggered.
