Abstract
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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
105 words
A portable alarm device comprising: (a) a housing; (b) means on said housing for supporting said housing on the person of an operator; (c) an alarm on said housing; and (d) a control circuit in said housing for controlling the operation of said alarm, (e) said control circuit including a manually actuable switch on said housing to activate said control circuit for operating said alarm, said control circuit once activated continuously operates said alarm until said control circuit is deactivated, said control circuit including an alarm deactivating switch on said housing manually actuable to deactivate said control circuit for discontinuing the operation of said alarm.
Claim 2
Dependent Claim
105 words
A portable alarm device comprising: (a) a housing; (b) means on said housing for supporting said housing on the person of an operator; (c) an alarm on said housing; and (d) a control circuit in said housing for controlling the operation of said alarm, (e) said control circuit including a manually actuable switch on said housing to activate said control circuit for operating said alarm, said control circuit once activated continuously operates said alarm until said control circuit is deactivated, said control circuit including an alarm deactivating switch on said housing manually actuable to deactivate said control circuit for discontinuing the operation of said alarm.
Claim 3
Dependent Claim
72 words
A portable alarm device as claimed in claim 1 wherein said housing includes a key slot, said portable alarm further comprising a key insertable in said key slot, movement of said key in said key slot actuating said alarm deactivating switch for deactivating said control circuit and movement of said key in said key slot actuating said alarm deactivating switch to enable said control circuit for activation by said manually actuable switch.
Claim 4
Dependent Claim
28 words
A portable alarm device as claimed in claim 2 wherein said manually actuable switch is spring loaded to reset said manually actuable switch upon release by an operator.
