Honeywell TC847A1004 Reflective Linear Beam Smoke Detector

Product Overview

TC847A1004 (A) is an intelligent coding single ended reflective beam smoke detector launched by Honeywell. It consists of a transceiver and a reflector plate, and triggers an alarm through smoke blocking light signals. It is designed specifically for tall/sloping ceilings and large open spaces, replacing traditional point detectors.

Core Features

Structure and Installation

Single ended integrated design, paired with transceiver and reflector, easier to install compared to reflector

Built in optical sight+two digital tubes for easy alignment without the need for specialized tools

The optical part can be independently adjusted by * * horizontal/vertical ± 10 ° * *

Sensitivity mode

Standard 4 levels: 25%, 30%, 40%, 50% shading rate

Acclimate ®  Automatic 2nd gear: 30-50%, 40-50%, software automatically adapts to the environment

Fault triggering: shading rate * * ≥ 96% * *, alignment failure, compensation exceeding the limit

Test function

Built in motor driven test filter, can remotely trigger sensitivity testing

Support RTS151/RTS151KEY remote test reset, no need to climb high

Meet the NFPA 72 annual testing requirements

automatic compensation

Built in automatic gain control to compensate for signal attenuation caused by dust accumulation

4. Key questions and answers

What is the maximum detection distance of TC847A1004 and how to achieve ultra long range?

Answer: The standard distance is 16~230ft (5~70m); For distances exceeding 230ft, BEAMLRK long-distance kit is required, which can be expanded up to 328ft (100m), and large-sized reflector plates need to be replaced.

What are the two automatic modes included in the six sensitivity levels of this detector and what are their functions?

Answer: Includes Acclimate ®  5 (30-50%) and Acclimate ®  6 (40~50%) two speed automatic mode; Relying on software algorithms to automatically adapt to the environment, dynamically adjust sensitivity, and avoid false alarms caused by dust, temperature differences, etc.

How can TC847A1004 achieve annual testing without climbing and meet NFPA 72 requirements?

Answer: The detector is internally integrated with a motor driven test filter, and is connected to an RTS151/KEYremote testing station with a 24VDC power supply. Remote triggering can simulate smoke shading testing sensitivity without the need for personnel to reach the detector installation location.
