Detection and Control Components
FAPT-851 Acclimate Plus™
Multi-Sensor Low-Profile Intelligent Detector
(IQ-318/IQ-636X-2)
Features
• Automatically adjusts sensitivity levels without the need for
operator intervention or programming. Sensitivity increases
with heat.
• Microprocessor-based, combination photo and thermal
technology.
• Compatible with FlashScan
®
systems
• Sleek, low-profile design.
• Rotary, decimal addressing 1 – 159 on FlashScan
systems.
• Addresses can be viewed and changed without the need
for electronic programmers.
• 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.
• Several base options, including relay, isolator, and
sounder.
• Built-in functional test switch activated by external magnet.
• Listed to UL 268.
• Capable of heat-only alarm mode, enabled by a special
command from the panel. Smoke alarms are ignored.
• Low-temperature signal at 45 °F (7 °C) +/– 10 °F (–12 °C).
Applications
The FAPT-851 Acclimate Plus™ detector is an intelligent,
addressable, multi-sensing, low-profile detector designed for
use on the AUTOPULSE IQ-318 or IQ-636X-2 control panel.
The Acclimate Plus detector uses a combination of photo-
electric and thermal sensing technologies that are designed
to increase immunity to false alarms. Unlike traditional intelli-
gent detectors, the Acclimate Plus detector has a micro-
processor in the detector head that processes alarm data. As
a result, the Acclimate Plus detector adjusts its sensitivity
automatically, without needing operator intervention.
Areas where the Acclimate Plus detector is especially useful
include office complexes, schools, college campuses, manu-
facturing and industrial facilities, and anywhere else the use
of a particular area may change. One day a conference
room, tomorrow a kitchen, the next day a copy machine
room – the Acclimate Plus detector automatically adjusts its
sensitivity to the environment.
