Fire-extinguisher monitoring system

A fire-extinguisher monitoring device including:

• a housing;
• and
• a monitoring device that is externally locatable relative to a fire extinguisher, the monitoring device being arranged or configured to non-intrusively monitor a status of the fire extinguisher such that a user can readily remove the fire extinguisher from a mount without having to unplug the fire extinguisher from the monitoring device, the status including at least one of a presence of the fire extinguisher and level of fire-suppression fluid contained by the fire extinguisher;
• wherein the monitoring device includes:
• an L-shaped arm slidably mounted to the housing and having a first portion and a second portion substantially perpendicular to the first portion, wherein the fire extinguisher is mounted on the second portion;
• and
• a sensor arrangement disposed within the housing such that, when the fire extinguisher is mounted on the arm, the arm slides downwardly due to the weight of the fire extinguisher, which causes the arm to contact the sensor arrangement to sense the presence.
