3NM FIRE AND SMOKE 250°F SERIES SPRING RETURN DIRECT COUPLED ACTUATORS
TYPICAL SPECIFICATION
Spring return actuators shall be direct coupled type requiring
neither crankarm nor linkage and be capable of direct mounting
to a jackshaft of up to 3/4 in. diameter. The actuator shall
connect to the shaft using a removable output hub with a self-
centering shaft coupling. This coupling shall provide concentric
mounting and include an integral adjustable range-stop
mechanism.
All spring return actuators must be designed for either clock-
wise or counterclockwise
continuously engaged mechanical spring. This spring must
return the valve or actuator to a fail-safe position within
25 seconds of power loss.
All actuators shall be designed for a minimum of 30,000 full-
stroke cycles at rated torque and 30,000 spring return cycles.
Run time shall be constant and independent of: load, tempera-
ture (operating temperature range), and supply voltage (within
specifications). All actuators shall be UL60730 and cUL
(CSA22.2) listed, have a five year warranty, and be manufac-
tured under ISO 9001 International Quality Control Standards.
Actuators shall be as manufactured by Honeywell.
IMPORTANT
The Actuator is designed to meet UL555S stan-
dard at 250°F (121°C) on applicable marked mod-
els. The actuator must be tested with the damper
to achieve this rating.

INSTALLATION

When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazard-
ous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Low voltage can shock individuals or short
equipment circuitry.
Disconnect power supply before installation.
IMPORTANT
All wiring must comply with applicable codes,
ordinances and regulations.
Location
These actuators are designed to mount directly to a
damper external drive shaft. The shaft coupling fastens to
the drive shaft. The actuator housing includes slots which,
along with an anti-rotation bracket, secure the actuator to
the damper frame or duct work (see Fig. 8).

fail-safe operation with
NOTES:
— When mounted correctly, these slots allow the
actuator to float without rotating relative to the
damper shaft.
— Using other brackets or linkages, the actuator
can be foot-mounted or tandem-mounted.
CAUTION
a
Motor Damage Hazard.
Corrosive vapors and acid fumes can damage
metal and plastic parts.
Install motor in areas free of acid fumes and other
deteriorating vapors.
CAUTION
Equipment Damage Hazard.
Tightly securing actuator to damper housing can
damage actuator.
Mount actuator to allow it to float along its vertical
axis.
Preparation
Before mounting the actuator onto the damper shaft,
determine the:
— Damper/valve opening direction for correct spring
return rotation. The actuator can be mounted to provide
clockwise or counterclockwise spring return by flipping
or turning the unit over.
— Damper shaft size (see the Specifications section).
Determine Appropriate Mounting
Orientation
The actuators are designed to open a damper by driving
the damper shaft in either a clockwise
counterclockwise
NOTES:
— Actuators are shipped in the fully closed
(spring return) position.
— The groove on the adapter points to a location
on the label to indicate the hub rotary position.
