Description
The OpenAir direct-coupled, 2-position,
spring return electronic damper actuators are
UL listed for smoke control dampers or for
combination fire/smoke rated dampers.
Actuators are designed to operate reliably in
smoke control systems requiring
Underwriter’s Laboratories, Inc. UL555/555S
rating when tested as an assembly with the
damper and will meet requirements of UBC
for 15 second opening and closing at 350°F
(177°C).
Features
• Optional built-in auxiliary switches: Fixed
switch points at 5° and 85° rotation.
• Optional built-in Electronic Fusible Link
(EFL) capability with three temperature
ratings; 165°F, 250°F, 350°F
• Reversible fail-safe spring return
• All metal housing
• Precabled Teflon
