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.

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.
