TPM Alarm Schematic
NOTES:
1. 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 CIRCUITRYmust still be supplied
to provide a resistive path to the return for the
local alarm to properly function.
2. The fuse is polarized to maintain proper orientation with
the switch housing. The line and load terminals are
identified on the switch housing.
