INSTALLATION INSTRUCTIONS

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.

3. Squeeze bulb

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.
