Honeywell 301C User Manual
Jumper Use Instructions
The jumpers on the controller PCB allow a variety of operations to be
performed manually:
EOL 1-4: Enables the user to add End-Of-Line jumpers that improve
communication signals. Put the jumper in R position (as
shown on wiring diagram) to activate the End-of-Line
termination. (R provides a resistance termination and RC
provides resistance and condensator termination.)
SHDN: Enables the microcontroller to be reset or temporarily shut
down. This function is used mainly when system wiring
adjustments are needed (power off for safety).
CAUTION
Power may still be present on the relay terminals even after
powering off.
Relays These jumpers allow the relay to be tested by activating it
J29-J32 without having any effect on Events.
