Description
General
The Notifier FAPT-851AUS-IV/ FAPT-851AUS-W Acclimate™ detector is an intelligent,
addressable, multi-criteria, low-profile detector designed for use with Notifier Fire
Alarm Control Panels.
The Acclimate™ detector uses a combination of photoelectric and thermal sensing
technologies to increase immunity to false alarms. Unlike traditional intelligent
detectors, the Acclimate™ detector has a microprocessor in the detector head that
processes alarm data. As a result, the Acclimate™ detector adjusts its sensitivity
automatically, without operator intervention or control panel programming.
Areas where the Acclimate™ detector is especially useful include office complexes,
schools, college campuses, manufacturing and industrial facilities, and anywhere else
where the use of a particular area may change over time. The Acclimate™ detector
automatically adjusts its sensitivity to the environment.
FlashScan® is a communication protocol developed to greatly enhance the speed
of communication between analogue intelligent devices and compatible systems.
Intelligent devices communicate in a grouped fashion. If one of the devices within the
group has new information, the panel’s CPU stops the group poll and concentrates
on single points. The net effect is response speed greater than five times that of
earlier designs.
Features
• Automatically adjusts sensitivity
levels without operator intervention
or programming. Sensitivity increases
with heat.
• Microprocessor-based, combination
photo and thermal technology.
• FlashScan and CLIP compatible.
• Sleek, low-profile design.
• Addressing by switch.
• Dual bi-color LED design provides
360° viewing angle.
• LEDs lock red when in alarm. In
FlashScan, LEDs flash green in standby for normal condition.
• Built-in tamper-resistant feature.
• Sealed against back pressure.
• Several base options, including relay,
isolator, and sounder.
• Built-in functional test switch
activated by external magnet.
• Capable of heat-only alarm mode,
enabled by a special command from
the panel.
