FCI LT81A-A1BE3B1B2CB Addressable Smoke Heat Detector

Overview

The FCI LT81A-A1BE3B1B2CB is an intelligent addressable multi-sensor detector under Gamewell-FCI fire alarm system. The FCI LT81A-A1BE3B1B2CB combines photoelectric smoke sensing and thermal sensing elements to monitor fire conditions simultaneously. It transmits analog environmental data to the fire alarm control panel for analysis and alarm judgment. The FCI LT81A-A1BE3B1B2CB can distinguish normal dust and real fire signals to reduce false alarms, and is widely deployed in commercial buildings and industrial facilities.

Features

The FCI LT81A-A1BE3B1B2CB integrates smoke and heat dual sensing for multi-criteria fire identification. It supports analog addressable loop communication to upload real-time sensor values to the FACP. The FCI LT81A-A1BE3B1B2CB has built-in self-test and contamination monitoring functions to remind maintenance. It adopts standard base mounting structure and is compatible with FCI addressable fire alarm loops. The FCI LT81A-A1BE3B1B2CB meets UL fire safety standards and runs stably in indoor public environments.

Specs

Device Type: Addressable smoke heat multi-sensor detector Model: FCI LT81A-A1BE3B1B2CBBrand: Gamewell-FCI (Honeywell) Sensing Type: Photoelectric smoke + heat sensor Communication: Analog addressable fire loop Installation: Detector base mounting Certification: UL listed Application: Indoor fire early warning

Principle

The FCI LT81A-A1BE3B1B2CB detects smoke concentration through the photoelectric chamber and collects ambient temperature via the thermal element. The internal circuit converts physical signals into digital data and sends them to the fire control panel. The control panel compares the received data with preset thresholds. When the fire characteristic condition is satisfied, the FCI LT81A-A1BE3B1B2CB participates in fire alarm triggering and status indication.

Applications

The FCI LT81A-A1BE3B1B2CB is used for fire detection in office buildings, shopping malls and hotels. It undertakes early fire warning for factory workshops and storage areas. The FCI LT81A-A1BE3B1B2CB applies to spare replacement and maintenance of existing FCI addressable fire alarm systems. It also serves fire safety renovation projects for public buildings.
