Typical Specification
On/Off spring return damper actuators shall be direct coupled type which require
o crank arm and linkage and be capable of direct mounting to a jackshaft up to a
1.05” diameter. The actuators must be designed so that they may be used for either
clockwise or counterclockwise fail-safe operation. Actuators shall be protected
from overload at all angles of rotation. If required, two SPDT auxiliary switch shall
e provided having the capability of one being adjustable. Actuators with auxiliary
witches must be constructed to meet the requirements for Double Insulation so
an electrical ground is not required to meet agency listings. Actuators shall be
cULus Approved and have a 5 year warranty, and be manufactured under ISO 9001
International Quality Control Standards. Actuators shall be as manufactured by
Belimo.
