Abstract
Mounted on a housing, which is adapted to be carried on the belt of an operator, is a manually activated alarm switch. In the event of an emergency, the operator activates the alarm switch to set off an alarm contained in the housing. The alarm switch is reset upon release. However, the alarm continues to operate until deactivated by a key switch. Formed in the housing is a suitable key slot for receiving a preselected key. The rotation of the preselected key in the key slot serves to deactivate the alarm.
