Yet another LACMÉ exclusive! Genuine guardian angels of the installation,
up to 4 Sentinels can be installed at critical points on the fencing to keep
the SECUR 2006 or 2006 ALT informed of the pulse quality received at these
points. Self-powered by the fence pulses, they do not require any battery or
230 V mains connection. Fitted at “milestones” (fig. 1 - example of a long
perimeter fence) or at the “end of the line” (fig. 2 - example of several
separate enclosures) Provided that the enclosure is suitably configured, they
can detect incidents such as crossing of an open barrier, a broken wire,
deterioration in earth rod connections and even insufficient conductivity in
the conductor or junction points. Finally, a mesh configuration (fig. 3)
provides a continuous diagnostic of the available power in each area.
