Noise Rating (Maximum):
Driving Open: 75 dBA at 1m.
Holding: 20 dBA at 1m (no audible noise).
Temperature Ratings:
Ambient: 0°F to 130°F (-18°C to 55°C).
Shipping and Storage: -40°F to 140°F (-40°C to 60°C).
IMPORTANT
The actuator is designed to meet UL555S standards
at 350°F (176°C). The actuator must be tested with
the damper to achieve this rating.
Humidity Ratings:
5% to 95% RH noncondensing.
Stroke:
95° ± 3°, mechanically limited.
Torque Rating (at rated voltage):
Spring Return:
MS4104F, MS4604F, MS8104F: 30 lb-in. (3.4 N•m).
MS4109F, MS4609F, MS8109: 80 lb-in. (9 N•m).
Stall Maximum:
MS4104F, MS4604F, MS8104F: 150 lb-in. (17 N•m).
MS4109F, MS4609F, MS8109: 240 lb-in. (27 N•m).
350°F Driving:
MS4104F, MS4604F, MS8104F: 30 lb-in. (3.4 N•m).
MS4109F, MS4609F, MS8109: 80 lb-in. (9 N•m).
Timing (At Rated Torque and Voltage):
Drive Open: 15 seconds typical.
Spring Close: 15 seconds typical.
Auxiliary Switches:
Ratings (maximum load):
• MS4104F, MS4604F, MS4109F, MS4609F:
25 Vac/24 Vdc, 3A resistive
• MS8104F, MS8109F:
24 Vac/24 Vdc, 3A resistive
Settings (fixed): 7° nominal stroke, 85° nominal stroke
Design Life (at Rated Voltage):
30,000 full stroke cycles.
Cycling Requirements:
The actuator and the internal spring are designed to require
no special cycling during long-term holding.
Honeywell recommends following all local, state and national
codes for periodic testing of the entire smoke control sys-
tem. Refer to National Fire Protection Association (NFPA)
National Fire Codes®: NFPA90A, NFPA92A and NFPA92B
for your application.
NFPA recommends periodic examination of each fire/smoke
damper (semi-annually or annually) to ensure proper per-
formance.
Minimum Damper Shaft Length:
2 in. (51 mm).
Mounting:
Round 1/2 inch shaft adapter with 1/4 inch set screws.
Threads: ¼-20 UNC-2A
Material: Alloy Steel hardened to HRC 45-53
Thread Lock: Nylon Patch
IMPORTANT
Honeywell does not recommend using linkages with
these actuators because side-loading of the output
hub reduces actuator life.
Environmental Protection Ratings:
NEMA, IP40.
Accessories:
205649 Mounting Bracket (not supplied with actuator).
