Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
85 words
An alarm device comprising: a protective loop, said loop including a coded module and a pair of conductors joined to said coded module, said conductors connected to normally opened and normally closed sensing means, a multi-functional alarm control means connected to said conductors, said multi-functional alarm control means containing an analyzer circuit for discriminating between normally open or normally closed violations and having high voltage and radio frequency input protection, said coded module and said analyzer circuit cooperating to prevent defeat of said sensing means.
Claim 2
Dependent Claim
85 words
An alarm device comprising: a protective loop, said loop including a coded module and a pair of conductors joined to said coded module, said conductors connected to normally opened and normally closed sensing means, a multi-functional alarm control means connected to said conductors, said multi-functional alarm control means containing an analyzer circuit for discriminating between normally open or normally closed violations and having high voltage and radio frequency input protection, said coded module and said analyzer circuit cooperating to prevent defeat of said sensing means.
Claim 3
Dependent Claim
26 words
An alarm device as claimed in claim 1 and including a trigger timer circuit for measuring the duration of the normally opened or normally closed violation.
Claim 4
Dependent Claim
14 words
An alarm device as claimed in claim 1 and including a telephone dialing means.
Claim 5
Dependent Claim
18 words
An alarm device as claimed in claim 1 wherein said multi-functional alarm control means includes multi-alarm actuating circuits.
Claim 6
Dependent Claim
