INSTALLATION INSTRUCTIONS
Honeywell Modutrol IV Series Actuators

Models M4182, M9185D, & M8182
UL Listed Electric Actuators with Two Position Control
These instructions apply to the external field installation of
Honeywell actuators on Greenheck model VCD Control Dampers,
FSD Fire/Smoke Dampers, and SMD Smoke Dampers when they
are duct mounted or sleeved.

Tools Required:
Wrenches:
(1) 3/8, (2) 1/2, (1) 9/16, (1) 7/16, and (1) 5/16
(1) Hammer

Honeywell actuators rotate to their energized position when power
is applied and spring return to their fail position when power is
interrupted, except for the M9185D which is a modulating actuator
that spring returns to the fail position when power is interrupted.
The M9185 model actuator, when installed on model FSD fire/
smoke and SMD smoke dampers in accordance with these
instructions, complies with the requirements of NFPA 90A and
UL Standards 555 and 555S. Smoke or Fire/Smoke dampers are
normally arranged to operate automatically in response to heat,
signals from a heat or smoke detector, or a building alarm system.
Installation must be acceptable to the authority having jurisdiction.

Instructions:
These installation instructions assume the damper is already
mounted in a duct or sleeve with the damper shaft extending
beyond the sleeve or duct 6 inches.
1. Install the stand off bracket (item 16).

Dampers with a jackshaft
1a. Mount the stand off bracket onto the jackshaft bracket with
(4) 1/4 -20 X 1/2 in. thread cutting screws (item 17). Use the
orientation shown on this page.
Note: The bracket must be perpendicular to the damper on
the duct or sleeve and the bracket's shaft hole must be
centered on the jackshaft.

Dampers without a jackshaft (Shaft Extension)
1b. Mount the stand off bracket (item 16) spanning across the
damper frame flanges. Use the orientation shown to the right.
Fasten to the damper frame with (4) #14 Tek screws, supplied
in the field. Be sure not to run the screws into the damper
linkage, which is between the flanges.

Damper

Note: The bracket must be perpendicular to the damper on
the duct or sleeve and the bracket's shaft hole must be
centered on the shaft extension.

2. Fasten the mounting plate (item 3) to the mounting bracket
(item 2) using (4) 1/4 - 20 x 1/2 in. thread studs (item 4), and (4)
1/4 -20 spinlock nuts (item 6), through the matching four hole
pattern on the mounting bracket labeled “A” on the
illustration. Note that the mounting bracket has only one
pattern that will match the mounting plate pattern.

3. Mount the mounting bracket (item 2) to the stand off bracket
using (4) 1/4 -20 x 1/2 in. bolts (item 21) and (4) 1/4 - 20 Spinlock
nuts (item 6) included with this kit. Use the outer four holes of
the mounting bracket for jackshafted models and the inner
four holes for directly driven models.
4. If the damper has a 1/2 in. dia. damper shaft, mount the ball
bearing (item 18), into the mounting bracket with two #10 Tek
screws (item 20). The Tek screws are required to keep the
thrust forces from pushing the bearing out of the mounting
bracket. If the damper shaft is 1 in. in diameter then no ball
bearing is required.

5. Mount the actuator to the mounting plate in the corresponding
holes using (3) 1/4 - 20 x 3/4 in. thread cutting screws (item 5).
Note that the actuator must be mounted with the shaft in the
horizontal position.

For dampers with 1/2 in. shafts:
The damper shaft crankarms must be placed as mirror
images of each other, meaning the like sides face each
other. The bolts and nuts are to be positioned as in the
exploded view.
For dampers with 1 in. shafts:
The 1 in. crankarm, item 10, must be in the position
shown in the encircled exploded view shown above left.
Position the bolt and nut as shown in the same diagram.
6b. For dampers with 1/2 in. shafts:
Insert a linkage adjustment pin through both of the
crankarm slots. Position it 3 in. from the center of the
damper shaft. Secure it there with a 1/4-20 spinlock nut
(item 6).

For dampers with 1 in. shafts:
Insert a linkage adjustment pin through the 1 in. crankarm
(item 10) slot. Position it 3 in. from the center of the
damper shaft. Secure it there with a 1/4-20 spinlock nut
(item 6).
6c. Attach the drive link to the damper shaft crankarms by
inserting the linkage adjustment pin through one of the
drive link’s holes and fastening it with an E-ring (item 14).

6d. Attach the drive link to the actuator crankarm with the
linkage adjustment pin, a spinlock nut and an E- ring
(item 14). Set the linkage adjustment pin 21/8 in. from the
actuator shaft center and secure it there with the spinlock
nut. Fasten the other end through the empty drive link hole
with the E-ring (item 14).
7. Note the damper shaft rotation for fail direction and orient
the linkage appropriately as shown in the linkage
illustration. The damper linkage is now in its fail position
Position the damper blades to their proper position (open
or closed). Tighten the bolts

8. Wire the actuator according to the
appropriate wiring illustration that
identifies the actuator’s electrical
connections. Wiring should be per an

The damper blades should fully open or
close and return to the fail position when
power is disconnected, if they do not,
adjustments can be made by resetting
the crankarm position on the damper or
actuator shaft, or by adjusting the 3 in.
dimension on the damper shaft crankarms.
