Emergency readiness verification system and method of calibration

An emergency readiness verification system for a fire extinguisher, the system comprising

• a housing,
• a secure weight-sensing mechanism,
• a vertically-actuated switch assembly,
• a vertically-adjustable calibration mechanism, and
• an alert device in communication with the vertically-actuated switch assembly, wherein:
• the housing comprises a removable faceplate;
• the secure weight-sensing mechanism is supported by the housing, is at least partially positioned behind the removable faceplate of the housing, and comprises a vertically-oriented weight-bearing spring, an extinguisher attachment, and an attachment extension;
• the removable faceplate of the housing comprises a vertically-oriented measurement aperture;
• the attachment extension of the secure weight-sensing mechanism extends from the extinguisher attachment along a vertical axis of the vertically-oriented weight-bearing spring, and comprises an engagement tab oriented to extend through the vertically-oriented measurement aperture;
• the vertically-adjustable calibration mechanism is secured to the removable faceplate and extends parallel to the vertically-oriented measurement aperture;
• the vertically-actuated switch assembly is secured to the vertically-adjustable calibration mechanism and comprises an actuator that is positioned to be engaged by the engagement tab of the attachment extension;
• the vertically-adjustable calibration mechanism is operable to fix a vertical position of the vertically-actuated switch assembly such that the engagement tab of the attachment extension engages the actuator of the vertically-actuated switch assembly when a weight of the fire extinguisher supported by the extinguisher attachment falls is within an alert threshold, and disengages the actuator of the vertically-actuated switch assembly when the weight of the fire extinguisher supported by the extinguisher attachment falls below the alert threshold or when the fire extinguisher is not supported by the extinguisher attachment;
• and
• the alert device generates an alert when the actuator of the vertically-actuated switch assembly is disengaged.
