Clopay Corporation has introduced a compact solution for its counter fire doors: the AlarmGard Conceal Motor Operator. Offered under the Clopay, Cornell, and Cookson brands, the new space-saving motor operator delivers alarm-triggered closure during a fire event while streamlining aesthetics. By enclosing the motor and controller within the door hood, AlarmGard Conceal reduces headroom requirements for the coil and operator by 279.4 mm (11 in.).
In addition to minimizing hood size, the AlarmGard Conceal Motor Operator can be installed flush with the ceiling, concealing the motor and operator and delivering a clean, soffit-like appearance. For counter fire doors 3.05 m (10 ft) and wider, AlarmGard Conceal also increases the bracket height and aligns the brackets with the stoppers for a seamless look.
The AlarmGard Conceal Motor Operator is UL (Underwriters Laboratories) 325 listed and features a standard onboard battery backup that prevents unintended drops during temporary power failures for up to one hour. Providing 24VDC failsafe performance without fusible links, the operator ensures deployment in alarm mode. Using electrical fire alarm signal connection points, the motor operator is directly notified by the fire alarm control panel or the local detector during a fire event or upon extended loss of power. The motor then closes the door at a controlled speed, and the brake engages once the door is in the closed position. When the alarm clears or power is restored, the door automatically opens and resets to its programmed position, eliminating the time-consuming task of manually resetting the door after an event.
AlarmGard Conceal’s compact size and chain-driven sprocket allow for out-of-shaft, front-of-pipe mounting, simplifying installation and maintenance. Located under the hood and outside the barrel, the motor operator is easily accessible through a convenient maintenance panel without removing the barrel, and all connections are plug-and-play.
