General

The Notifier FAPT-851(A) Acclimate® Plus™ detector is an

intelligent, addressable, multi-sensing, low-profile detector

designed for use with Notifier Notifier Onyx and CLIP series

Fire Alarm Control Panels (FACPs).
The Acclimate Plus detector uses a combination of photoelec-

tric and thermal sensing technologies to increase immunity to

false alarms. Unlike traditional intelligent detectors, the Accli-

mate Plus detector has a microprocessor in the detector head

that processes alarm data. As a result, the Acclimate Plus

detector adjusts its sensitivity automatically, without operator

intervention or control panel programming.
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. The Acclimate Plus detector

automatically adjusts its sensitivity to the environment.
FlashScan® (U.S. Patent 5,539,389) is a communication pro-

tocol developed to greatly enhance the speed of communica-

tion between analog intelligent devices and compatible

systems. Intelligent devices communicate in a grouped fash-

ion. If one of the devices within the group has new information,

the panel’s CPU stops the group poll and concentrates on sin-

gle 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.

• Compatible with all Notifier Onyx and CLIP series Fire

Alarm Control Panels (FACPs).

• Addressable-analog communication.
• Sleek, low-profile design.
• Two-wire SLC connection.
• Rotary, decimal addressing (1-99 on CLIP systems, 1-159

on FlashScan systems).

• Addresses can be viewed and changed without 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.

• Built-in tamper-resistant feature.
• Constructed of off-white fire-resistant plastic, designed to

commercial standards, and offers an attractive appearance.

• SEMS screws for wiring of the separate base.
• 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 +/– 10°F (7.22°C +/–

5.54°C).

simplify installation, service, and maintenance. A special tool

allows maintenance personnel to plug-in and remove detec-

tors without using a ladder. Suitable mounting base boxes

include:
