The GST DI-9101E Intelligent Combination Heat Photoelectric Smoke Detector (Product No. 10106285) is engineered for full protocol integration with Gulf Security Technology (GST) intelligent fire alarm systems. To ensure seamless deployment, field commissioning, and standard-compliant reporting, system designers and installation engineers must align panel protocols, base variants, peripheral accessories, and electrical loop parameters.
Intelligent Fire Alarm Control Panel Compatibility
The DI-9101E operates on addressable loops driven by compatible GST intelligent fire alarm control panels. It natively communicates over the proprietary GST intelligent loop protocol, transmitting dual-criteria smoke obscuration and thermal data directly to the head-end automation system. Certified compatible panels include:
- GST100 Intelligent Fire Alarm Control Panel
- GST200N Intelligent Fire Alarm Control Panel
- GST-IFP4E Intelligent Fire Alarm Control Panel
- GST-IFP8 Intelligent Fire Alarm Control Panel
Approved Detector Bases & Peripherals
The detector interfaces mechanically and electrically with compatible GST mounting bases and auxiliary modules. Field engineers must select from the following verified hardware units:
- DB-01 Standard Base (Product No. 30205764): Standard twist-lock base supplied for conventional installations. Features terminals 1 and 3 for non-polarized loop connections, terminal 2 for remote indicator positive (+), and terminal 4 for remote indicator negative (-).
- DC-9504E Diode Base (Product No. 10105103): Specialized diode base engineered for specific loop continuity monitoring architectures.
- C-9314P Remote Indicator (Product No. 10102339): Remote LED annunciator powered directly via the detector’s polarized remote output. The DI-9101E integrates a built-in 10kΩ series resistor providing a regulated 2mA output current that causes the C-9314P to flash during an alarm condition and remain unlit during standby.
- P-9910B Handheld Programmer (Product No. 10104894): Essential field tool required to set electronic address codes within the range of 1 to 242 and configure programmable sensitivity profiles (e.g., parameter codes 1, 129, and 130).
Electrical Loop Parameters & Sizing
The DI-9101E draws operating power directly from the 2-wire signaling line circuit (SLC). To ensure stable performance across all loops, calculate electrical loading within the following engineering boundaries:
- Loop Operating Voltage: Nominal 24V DC, operational range from 16V DC to 28V DC.
- Standby Current Draw: ≤0.8mA per unit during regular polling.
- Alarm Current Draw: ≤1.8mA (without remote indicator connected); ≤3.8mA (when driving a remote indicator such as the C-9314P).
- Field Cabling: Requires 1.0mm² or greater cross-section fire-rated cable laid through metal or flame-retardant conduit. Distinct cable colors must be utilized for the remote indicator connections to eliminate polarity reversal.
Mounting Box & Structural Compatibility
The DB-01 mounting base is designed to mount onto standard European embedded electrical back boxes with screw fixing centers ranging from 45mm to 75mm. The unit connects to the base by aligning alignment mark A on the detector body with mark B on the base, followed by clockwise rotation until mark A locks into alignment with mark C. The assembled detector and base measure 100mm in diameter and 54.5mm in height, operating reliably under flat ceilings up to 25 meters high with an individual smoke detection radius of 7.5 meters.
