Commercial sites have needs that are very different from
residential applications, frequency of use being the most common difference.
Whereas the typical garage door opener may only be used a few times daily, a
commercial operator may be used several times an hour. With this heavy
industrial usage in mind, LiftMaster has developed a full line of operators that
provide the highest levels of strength and durability. LiftMaster professionals
can assess precisely what you need and install a reliable system your business
can count on for many years to come.
Fire Door Release Device Systems
LiftMaster Fire Door Systems control the closure of a rolling fire door, counter
fire door, fire shutter, or track door in an emergency situation, and stop the
spread of fire and smoke from one area to another.
Fire doors and shutters are found in virtually all types of commercial buildings,
including manufacturing facilities, warehouses, hospitals, stadiums, sports
arenas, convention centers, and food court areas. They serve as physical
barriers to stop the spread of fire and smoke from one area to another.
LiftMaster fire door release devices enhance the performance of these safety
barriers by controlling the closure of the fire doors upon receipt of a signal
from the smoke detector, heat detector, or building fire alarm system. The
devices are an integral part of the door or shutters fusible link release
assembly, providing fail-safe performance.
Ultimately, LiftMaster fire door release devices are
designed to minimize property damage and provide increased safety for all
building occupants. They provide a time-delayed release of the door for a period
of up to 60 seconds to permit passageway clearance prior to door closure.
Optional battery backup can ensure the door will not be released as a result of
power failure (in non-alarm conditions) for up to 72 hours. For added safety of
the individuals in or around the opening, a voice annunciator, strobe, or horn
notification device can be installed to provide a verbal, visual, or auditory
warning message prior to door closure.
Models are available for use with both non-motorized and
motorized door applications. For motorized door applications, select models can
be used to create a fully automated door closing system when used in conjunction
with a standard commercial operator by providing features typically found on
expensive, special-order fire door operators.
Fire Door Release Devices
LiftMaster offers a choice of three different models for both motorized and
non-motorized applications. Each model can be customized with accessories and
options to provide added features and flexibility to upgrade your system.
Each LiftMaster fire door release device serves as an interface between the
smoke detection system and fire door. As the central control, the fire door
release system receives and interprets all signals to instruct the fire door and
all warning devices to act appropriately.
LiftMaster offers a choice of three different models,
for both motorized and non-motorized applications. For motorized applications,
the appropriate release device works in conjunction with a standard, commercial
electromechanical or solid-state operator to create an enhanced, yet economical,
fire door operating system. All devices ensure the continued protection and code
compliance for the fire door or shutter by enabling routine operation
inspections without activating the primary alarm system and without disturbing
building occupants. All our fire door release devices are C-UL-US, FM, and CSFM
listed and are compliant with the NFPA 80 requirement for a fail-safe door
