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 Accessories
LiftMaster fire door release devices offer a choice of
accessories and options that provide added features and flexibility to upgrade
your system.
LiftMaster Fire Door Release Device Accessories include smoke detectors, heat
detectors, speaker/strobes, and notification devices. They are designed to give
individuals in or around the door opening added safety by providing a verbal,
visual, or auditory warning message prior to the door closing.
LiftMaster also offers options that provide added features and
flexibility to upgrade the fire door release device system, including voice
boards, transformers, and an FDR plug-in Option card.
Smoke Detectors
Smoke detectors can be used to provide a local alarm signal that activates the
release device. Three types of detectors are available: Photoelectric,
Photothermal detectors, or Ion detectors.
Heat Detectors
Heat dectectors provide an alarm signal that activates the release device when
the ambient temperature reaches a fixed point. They are available in fixed
temperatures of 135 and 194 degrees Fahrenheit.
Speaker/Strobe
A speaker/strobe is an audible/visual notification device used in conjunction
with our optional Voice Board. The speaker/strobe is available in 12VDC, 24VDC,
or 120VAC. A stand-alone speaker is also available. All speaker/strobes are
ADA-compliant.
Notification Devices
Notification devices provide a visual and/or audible warning notification.
Available types include a stand-alone horn, stand-alone strobes, or a
combination horn/strobe. Each type is available in 12VDC, 24VDC, or 120VAC. All
notification devices are ADA-compliant.
Voice Board
Voice Board A solid-state speech module, the optional voice board (VB) may be
ordered factory-installed within the XPBB or AFCB models, or purchased
separately for retro-fit applications. In an alarm condition, the voice board
will provide a warning tone followed by a voice message/warning prior to door
closure. It can be used with up to two speaker/strobes or stand-alone speakers.
Transformer
The transformer is used in conjunction with an AFCB model when line voltages
other than 120VAC are present at the door installation. Transformers are mounted
within an UL508 approved enclosure and are available in the following two
options: 90-TRNSFRMR-2 (208VAC 1/3 Phase, 230/460VAC 3 Phase), and 90-TRNSFRMR-5
(575VAC 3 Phase).
FDR Plug-in Option Card
The FDR plug-in option card is for use in conjunction with the LiftMaster Logic
3-equipped operator. It facilitates field connections between the LM21AFCB and
the operator by reducing the standard 10-wire interconnection to a basic 4-wire
phone cord. Both the FDRCARD and the AFCB are equipped with an RJ-11 phone jack
as standard to accept the phone cord. The FDRCARD also eliminates the need for
ordering the operator with auxiliary open and close limits, which are required
for all non-Logic 3 operators.
