MP909E
UL Listed Damper Actuator
BEFORE INSTALLATION
The MP909E UL Listed Pneumatic Damper Actuator is used
for control of Leakage Rated (Smoke) Dampers, classified
under Underwriters Laboratories Standard 555S, for use in
smoke control systems.The MP909 is a piston-type, rolling-
diaphragm operated actuator and can be mounted in any
position and installed either externally or internally.
The UL listing of the actuator and the damper classification
apply only when Listed Honeywell Actuators are installed on
Honeywell D640SD, D641SD, D644SD, or D645SD Series
Dampers as specified in the installation instructions shipped
with the devices.
All installations must also comply with the requirements of
NFPA 90A, National Fire Protection Standard for the
Installation of Air Conditioning Systems.
Table 1 lists the only MP909 Actuators approved for use with
UL Classified Leakage Rated (Smoke) Dampers.

INSTALLATION
External Mounting
1For external mounting dimensions, see Figure 1.
2Check faceplate position (Fig. 2).Adjust faceplate
position if necessary.
3Determine the damper drive axle direction of rotation to
the normal position (position with 0 psi applied to
actuator).
4Rotate damper drive axle to normal position.
5Locate proper shaft hole (Fig. 3) over damper shaft.
Arrow on bracket surrounding hole should match
rotation determined in Step 3.
6Position mounting bracket.
7Secure mounting bracket. Use four of the 10 holes
available in bracket and drill screws provided.
8To provide close-off force, use a squeeze bulb and
stroke the actuator:
a. For normally open dampers, fully extend actuator
shaft then retract 1/2-inch (13 mm).
b. For normally closed dampers, extend actuator
shaft 1/2-inch (13 mm).
CAUTION
See Figure 4 for proper tightening of crankarm bolts.
9Go to PIPING section.
Internal Mounting
Normally Closed
1For normally closed internal mounting dimensions, see
Figure 5.
2Check faceplate position (Fig. 6).Adjust faceplate
position if necessary.
3Use a 1/8-inch Allen wrench to loosen mounting set
screws on damper mounting clamp (Fig. 6) one turn.
Remove and discard shipping stop.
4Locate factory-installed drive ear on damper. (Mounted
per Damper Ordering Instructions.) Actuators must be
mounted only in this (these) position(s)

3Use 1/8-inch Allen wrench to loosen set screws on
mounting clamp (Fig. 6) one turn. Remove and discard
shipping stop.
4Determine height of damper drive blade. Dampers
with 10, 12, 18, 26, 34, and 42-inch B dimensions
have 8-inch drive blades. All others have 6-inch drive
blades.
5For installation with 6-inch drive blades, go to Step 6.
For installation with 8-inch drive blades, remove clevis
pin A (Fig. 8) and reinstall in pushrod hole marked 8.
(Hole in crankarm marked 90.)
6Locate factory installed drive ear on damper. (Mounted
per Damper Ordering Instructions.) Actuators must be
mounted only in this (these) position(s).
7Loosen truss link to actuator base mounting screw.
Remove clevis pin C from damper pushrod.
8Set actuator in place by hooking mounting clamp over
bottom edge of damper frame.
9Connect damper pushrod to damper drive ear with
clevis pin.

Piping
Special piping is required for Leakage Rated (Smoke)
Damper actuators.The piping from the actuator to the device
which interfaces to the smoke control system must be 1/4-inch
copper tubing or as required by local code. 1/4-inch polyester
tubing pigtails are provided with the actuator to interface with
the copper tubing.
Figure 9 shows how to adapt 1/4-inch copper tubing to
polyester tubing. CCT1635B compression adapters connect
the 1/4-inch copper tubing to the 1/4-inch polyester.These
adapters must be ordered separately.
Copper tubing can be connected directly to the actuator as
shown in Figures 10 and 11.
