NOTES:

1

.

The relay contacts are shown after a reset

pulse, which represents the non-alarm

condition.

2

.

If the relay contacts are being used to control

120 V

AC operated equipment, ensure that

the conduit is properly attached to the

internal metal ground strap, using the proper

conduit locking nuts. 

Failure to provide

proper grounding may result in fatal

electrical shock and violation of national

and local codes.
