Alarm Schematic
NOTES:
1. The Electronic Monitoring Circuit (EMC) is a high input
impedance device that will provide alarming for an
open-fuse condition.
2. Typical leakage current through the load when the EMC
is operational ≤2 mA.
3. The resistance, R, must be provided by the end-user to
limit the alarm output current to a maximum of 20 mA.
The value, R, should be calculated using the system
voltage value.
•If remote alarm functionality is not required, the
END-USER CIRCUITRY
must still be supplied to
provide a resistive path to the return for the local
alarm to properly function.
4. The fuse is polarized to maintain proper orientation with
the switch housing. The line and load terminals are
identified on the switch housing.
5. Electrical integrity of the load must be maintained after
fuse has opened in order for the local and remote alarm
to properly function.
