Description

The GST I-9101 is an advanced analog addressable multi-sensor fire detector manufactured by Gulf Security Technology (GST / Carrier) for commercial, industrial, and institutional safety networks. Integrating an optical light-scattering photoelectric smoke chamber with a precision thermistor temperature sensor within a sleek low-profile white enclosure, the detector evaluates smoke particle density and rate of temperature rise simultaneously. Driven by an onboard 8-bit MCU executing dynamic signal processing algorithms, the unit rapidly identifies diverse fire signatures—from slow-smoldering fires to fast-flaming blazes—while delivering high immunity to deceptive false alarm sources. Operating across a 16V to 28V DC 2-wire addressable loop using the GST protocol, it supports electronic digital soft addressing via the P-9910B handheld programmer, automatic optical chamber drift compensation, twin 360-degree status LEDs, remote indicator outputs, and full LPCB and CE certifications under EN 54-5 and EN 54-7.

Features

  • Dual Opto-Thermal Sensing: Combines a photoelectric optical chamber with thermistor temperature monitoring for early detection of both smoldering smoke and fast-burning fires.
  • Multi-Level Sensitivity Control: Offers three programmable sensitivity modes configurable at the panel or via programmer to adapt to specific room environments.
  • Automatic Drift Compensation: Built-in algorithms adjust baseline detection thresholds over time to compensate for dust accumulation and reduce false alarms.
  • Soft-Addressing Capability: Simplifies setup and maintenance by assigning digital address codes electronically via a handheld device without physical DIP switches.
  • 360-Degree Visual LED Status: Outfitted with twin status LEDs to ensure omnidirectional visibility for normal polling flashes and continuous red alarm indications.
