with external magnets virtually impossible. The
contacts feature tamper circuits that are actuated
by removal of the face plate or by introduction of
an external magnet. The terminals are located
inside the housing providing additional protec-
tion from tampering or accidental shorting.
Optional features include pry tamper loop for
alarm in case of contact removal, current limiting
device for circuit protection, and a housing
approved for Class1 Group B and Class III envi-
ronments.
