INTRODUCTION
The HPO-6704 converts a standard analog
voltage output to a 4–20 mA output while
providing an adjustable potentiometer for
override settings while in the “Hand” position.
NOTE: The HPO-6704 board supplies the
power and will not work with a 4–20
mA device that also supplies its own
power.
Each output board has a red LED indicator that
turns On when the board’s output is turned On
either manually or automatically.
Output boards have an accessible three-position
slide switch for selecting the “Hand-Off-Auto”
functions:
While in the H (“Hand” or manual On) position,
the output is manually energized, and the
controller is provided with a feedback signal to
indicate the output has been overridden.
While in the O (Off) position, the output is
manually de-energized, and the controller is
provided with a feedback signal to indicate the
output has been overridden.
While in the A (Auto) position, the output is
under the command of the controller.
NOTE: An HPO-670x-1 is always in auto mode
and does not have the manual slide
switch.
NOTE: HPO-6701 triac and HPO-6703/6705
relay circuits use the Switched
Common SC terminal—not the Ground
Common GND terminal.
NOTE: HPO-6701 triac outputs are for 24 VAC
only.
NOTE: Only the HPO-6701triac and HPO-
67044–20 mA boards are approved
for smoke control applications. For
smoke control application information,

For enhanced controller output options (such
as manual control, using large relays, or for
devices that cannot be powered directly from a
standard output), install output override boards
(in compatible controllers). The following types of
override boards are available:
The HPO-6702 enhances the analog voltage
output with a “Hand-Off-Auto” control while
providing an adjustable potentiometer for
override settings while in the “Hand” position.
The HPO-6701/6703/6705 boards are
designed to convert a binary/digital output
to a relay contact or triac output and to
provide “Hand-Off-Auto” control and feedback
functions.
