Features:
- 30 lb-in. (3.4 Nm) minimum driving torque at 350°F (176°C).
- Integral spring return ensures level of return torque.
- Stainless steel internal spring.
- Fifteen-second spring return timing.
- No special cycling required during long-term holding.
- No audible noise during holding.
- Patent pending design eliminates need for limit switches to reduce power consumption.
- Models available for 24 and 120 Vac.
- Ninety-five degree angle of rotation.
- Actuator holds rated torque at reduced power level.
- Die-cast aluminum housing.
- Housing design allows flush mounting to damper.
- Integral junction box with three conduit openings
Specifications:
- Minimum Damper Shaft Length: 1-3/4 in. (45 mm).
- Device Weight: 5 lb (2.3 kg).
- Stroke: 95° ± 3°, mechanically limited.
- Honeywell does not recommend using linkages with these actuators because side-loading of the output hub reduces actuator life.
- 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).
- 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.
- Noise Rating (Maximum):
- Driving Open: 65 dBA at 1m.
- Holding: 20 dBA at 1m (no audible noise).
- Cycling Requirements: Prolonged holding-period (1 year) testing of these actuators has been performed with no spring return failures. 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 system. 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 performance.
- Design Life (at Rated Voltage): 60,000 full stroke cycles.
