An extinguisher’s pull pin may be routed through the holes in both prongs of the clip, the clip is then held in place by the extinguisher’s seal and when the seal is broken to use the extinguisher, the alarm sounds. The steel clip can also be placed under any type of equipment. When the protected equipment is moved, the clip opens and the alarm sounds immediately.

Product Information N/A Mini Theft Stopper® has two versatile methods of activation. This flexibility of design and compact housing allows this multipurpose unit to protect equipment or cabinets of virtually any kind without sacrificing performance.
Reed Switch/Magnet Activation N/A This method of activation is the reed switch and magnet which can be used to protect doors and cabinets, etc. The Mini Theft Stopper is mounted next to the door or in the cabinet, the reed switch mechanism on the door jam as shown below and the magnet is mounted on the door so that when it is closed it is in close proximity to the reed switch. When opened, the alarm will immediately activate.
Versatile Spring Steel Activation N/A A special spring steel clip offers a variety of possibilities. The clip may be used to protect free-standing fire extinguishers by routing the extinguisher's pull pin through the holes in both prongs of the clip, the clip is then held in place by the extinguisher’s breakaway seal. When the seal is broken to use the extinguisher, the alarm immediately sounds. The steel clip may also be placed under almost any type of equipment. When the protected device is lifted, the clip expands and the alarm will sound immediately. NOTE: If the extinguisher pin method is used, the State of California requires installation of pin seal by a licensed fire extinguisher contractor.
Note N/A In moderate to high noise, a sound level check should be done (monthly) to verify audibility in all areas the unit is to alert. End user must verify the alarm and battery function every six months and replace battery annually or as required.
