The GST DI-9103E Intelligent Rate of Rise and Fixed Temperature Heat Detector is engineered to interface directly with Gulf Security Technology (GST) intelligent fire alarm networks. Built for commercial and industrial fire detection installations, the DI-9103E integrates into GST addressable loops via standardized communication protocols, providing real-time analog data transmission, remote diagnostic telemetry, and selectable EN 54-5 thermal operating classes (Class A1R, Class A2S, and Class BS).
GST Intelligent Fire Alarm Control Panels
The DI-9103E detector head communicates over dedicated addressable signaling loops managed by GST intelligent fire alarm control panels (FACPs). The unit is validated for native integration across the following GST control equipment:
- GST-IFP8 Series: Modular intelligent fire alarm control panel supporting up to 8 loops, engineered for large-scale enterprise and industrial facilities.
- GST200-2 & GST200N Series: Intelligent addressable fire alarm panels designed for medium-sized commercial projects requiring networked loop topologies.
- GST100 Series: Compact single-loop addressable control panels suitable for smaller installations and remote utility structures.
Mounting Base and Base Mount Isolator Compatibility
Supplied standard with the DB-01 common mounting base (GST product code 30205764), the DI-9103E uses a 100 mm diameter white ABS flame-retardant (UL94 V-0) mechanical interface. The DB-01 contains no active electronic circuitry and features universal mounting slots spaced 45 mm to 75 mm apart to mate with standard back boxes. For projects requiring distributed short-circuit protection at every sensor location, the detector head is interchangeable with the GST DC-9504E base mount isolator (GST product code 10105103). The DB-01 mounting footprint also shares physical compatibility across several GST detector series:
- GST DI-9000E Digital Intelligent Series: DI-9101E, DI-9102E, DI-9103E.
- GST DC-9000E Conventional/Intelligent Series: DC-9101E, DC-9102E, DC-9103E.
- Specialty Detectors: DI-9405, DI-9406.
Field Programming and Peripheral Integration
System integrators configure the DI-9103E within an electronic address range of 1 to 242 prior to base insertion, avoiding physical DIP switches. Addressing and device mode configuration are executed using the dedicated GST P-9910B handheld electronic programmer. For ceiling voids, electrical closets, or locked plant rooms requiring secondary visual annunciation, terminals 2 and 4 on the DB-01 base interface directly with the GST C-9314P passive remote indicator lamp.
Loop Electrical Parameters and Field Cabling
The detector operates over a wide loop supply range of 16VDC to 28VDC with a nominal 24VDC supply voltage. Current load calculations should allocate a quiescent standby current of ≤0.6 mA per detector, rising to ≤1.5 mA during an active fire condition without a remote indicator, or ≤3.5 mA when driving an illuminated external C-9314P remote indicator. Loop field wiring connects to non-polarized terminals 1 and 3 on the DB-01 base using 2-core fire-rated cabling (minimum cross-sectional area of 1.0 mm², with 1.5 mm² recommended for extended loops up to 1,500 meters).
