The connection circuits of the peripheral detection/activation devices are defined as “loops”. These loops start from the output terminals, run through the entire protected area connecting in parallel all the system devices before re-entering on the input terminals.The loop utilizes the same two wires for the power supply to devices and for two-way communication. Due to electrical incompatibility, different brand devices (i.e. devices using different protocols) cannot co-exist on the same loop. However, the loops can be programmed separately in such a way as to allow the system to manage different brand devices on different loops.Loops are made by means of a two-wire shielded cable with proper wire section (refer to the following cable specifications) and in compliance with local laws in force.The wiring must be completed in a loop in order to guarantee the tolerance of wire-cutting or short-circuit on the cable.Cables:
