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.
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.
Note: These actuator models require fi eld
calibration for the zero and span setting.
