Reality

It is a shame the gentleman in question died. However surely common sense also applies. If a person is at high risk then in the absence of their alarm he should have had 24hr care.

How many panic type alarm systems are not working at anyone time I wonder? This is the reason to encourage the resident to test on a regular basis. Weekly should be a minimum.

As you get no advanced warning of a failure. As for the argument the devices should self test/ more robust, yes all this is achievable but at a cost and how many councils would want the increased cost.
