hi tnuflora,
Look at the attached pdf.
The design has been built and checked OK, using loop resistances of 330K thru 1M0 and a short circuit loop.
You will understand, as I will not be the person building and using this unit I will not be held responsible
for any damage or injury that may result from using this design.

i was working with the circuit that u have given.
In that safe operation is working fine.but
fault condition is not at all indicating.
can u give some more details about the working of the circuit ?

Regarding the Fault, this LED will light if the high value resistor has been removed from the strap and a link used to replace the resistor.
In other words its a strap with no series protection resistor, which is UNSAFE.
I have seen instances where the wire with the resistor has broken away from the wrist strap, due daily use, and the user has connected just a piece of wire to the strap, which is a bad idea.
