Posted for a friend not (yet) on the network: "I need assistance in shopping for burglar alarms. There seems to be a lot of different opinions on 'glass break' sensors (mercury switches vs. sound detectors, etc.). Any information or opinions would be appreciated." Please mail responses to the address given below and I will forward them. I will summarize to this group if there is sufficient material. Thanks. ...utzoo!dciem!nrcaero!nrccgs!mackay
