Description

The GST DC-9101E is an intelligent conventional multi-criteria fire detector manufactured by Gulf Security Technology (GST / Carrier) for commercial, industrial, and residential fire alarm installations. By combining an optical light-scattering photoelectric smoke chamber with a precision thermistor thermal element within a sleek white enclosure, the detector monitors smoke particle concentration and rate of temperature rise simultaneously. Driven by an onboard 8-bit MCU executing dynamic signal cross-referencing algorithms, the unit responds swiftly to both slow-smoldering fires and fast-flaming blazes while offering high immunity to false alarms caused by transient dust or environmental fluctuations. Operating across a 16V to 28V DC conventional zone loop, it features automatic optical chamber drift compensation, programmable sensitivity settings via the P-9910B handheld programmer, 360-degree omnidirectional LED indication, remote indicator driver output, and full LPCB and CE certifications under EN 54-5 and EN 54-7.

Features

  • Dual Opto-Thermal Sensing: Integrates an optical smoke chamber with rate-of-rise thermal detection to reliably detect smoldering, fast-flaming, and small-particle fires.
  • Intelligent Drift Compensation: Automatically adjusts sensor algorithms to compensate for environmental changes and internal dust accumulation over time.
  • Programmable Sensitivity Levels: Allows field adjustment of smoke sensitivity and polling status using an optional handheld programmer.
  • 360-Degree Fire LED Status: Features an all-around visible red LED that flashes during normal polling and stays solid in alarm conditions.
  • Easy Maintenance & Diagnostics: Built with a removable optical sensing chamber, dirty chamber self-checking, and reed switch test functionality.
