INTRODUCTION

Hand-Off-Auto

Switch (Not
Included with
HPO-670x-1)

LED Output

Indicator

Manual/Hand

Output Adjustment

(Potentiometer

on HPO-6702 and

HPO-6704)

 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.

HPO-6701

(Triac)

HPO-6702

(0–10 VDC)

HPO-6704
(4–20 mA)

HPO-6703
(NO Relay)

HPO-6705
(NC Relay)

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.

 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-6701 triac and HPO-

6704 4–20 mA boards are approved
for smoke control applications. For
smoke control application information,

KMC Controls, 19476 Industrial Drive, New Paris, IN 46553 / 877.444.5622 / Fax: [phone] / www.kmccontrols.com

see Smoke Control Manuals 000­035-08 (BACnet) and/or 000-035-09
(KMDigital).

2. Pull the top edge of the (translucent black)
override board cover away from the case and
flip open the cover.

CAUTION

Connecting 24 VAC or other signals that

exceed the operation specications of
the controller before an override board

is installed will damage the controller.

For HPO-6700 series specications, see the data

sheet at kmccontrols.com.

See the sections below for installation into the

particular type of controller.

 For KMC Conquest BAC-5900 series

controllers and CAN-5901 expansion modules,
see Conquest Controllers/Modules on page

2.

 For older controllers with “top-mounting”

raised plastic cases (BAC-5801/5802 and

newer KMD-5801/5802s), see Older “Plastic”

Case Controllers on page 3.

 For older controllers with metal (e.g., BAC-

5831, BAC-A1616BC) and older “side­mounting” plastic cases (older KMD-

5801/5802s), see Older “Metal” Case

Controllers on page 4.

CONQUEST CONTROLLERS/MODULES

These instructions apply to KMC Conquest BAC­5900 series controllers and CAN-5901 expansion
modules (with a flip-open lid).

1. Disconnect the power by removing the black

power terminal block.

2

3. Remove the jumper from the slot in which the
override board will be installed.

3

NOTE: Each of the eight override slots ships

from KMC with a jumper installed on
the two pins closest to the output
terminal blocks. Only remove a jumper
if an override board will be installed.

4. Orient the override board with the HOA
selection slide switch toward the top of the
controller.

5. Slide the override board into the slot in which
the jumper was removed.
