The GST C-9329 Gas Extinguishing Control Relay Module (Product Number 10102343) is engineered by Gulf Security Technology Co., Ltd. to interface dedicated fire extinguishing releasing circuits with central gas extinguishing control systems. Built in full conformance with EN 54-18:2005 standards, the module functions as the specialized physical and signaling bridge between automated panel releases and mechanical suppression hardware.
Extinguishing Control Panel Interfacing
The C-9329 is verified for direct system-level integration with the following Gulf Security Technology extinguishing control panels:
- GST303 Gas Extinguishing Control Panel: Complete integration for actuation signaling, field status monitoring, and loop event reporting.
- GST306 Gas Extinguishing Control Panel: Multi-zone interface compatibility supporting automated extinguishing commands, feedback relays, and pressure fault monitoring.
Start command activation lines from the host panel wire directly into module terminals DC1+ and DC1-. System verification and confirmation signals are returned to the gas extinguishing control panel via dedicated output terminals YK1 and YK2, ensuring real-time operational feedback across all stages of suppression activation.
Cylinder Actuator & Pressure Switch Compatibility
The C-9329 module features dedicated terminal pairs configured to interface directly with field-mounted suppression hardware:
- Solenoid Valve Actuation (Terminals J11 and J12): Delivers the gas extinguishing start command output directly to the cylinder discharge solenoid. The internal relay provides a robust contact rating of 30VDC at 2A.
- Pressure Switch Monitoring (Terminals K11 and K12): Serves as the primary input for cylinder pressure switches, reporting discharge status and pressure verification back to the primary extinguishing panel.
- Auxiliary Volt-Free Switching (Terminals COM and NO): Provides a secondary dry contact output configured to trip concurrently with the start command, allowing integration with third-party visual indicators, auxiliary interlocks, or facility shutdowns depending on field conditions.
Terminal Interface & Circuit Architecture
| Terminal Designator | Interface Function | Compatible Field Connection |
|---|---|---|
| DC1+, DC1- | Extinguishing Start Input | Gas Extinguishing Control Panel (GST303 / GST306) |
| YK1, YK2 | Feedback Signal Output | Gas Extinguishing Control Panel Status Input |
| J11, J12 | Suppression Release Output | Cylinder Solenoid (Rated up to 30VDC / 2A) |
| K11, K12 | Discharge Confirmation Input | Extinguishing Cylinder Pressure Switch |
| COM, NO | Volt-Free Contact Output | Auxiliary Field Equipment / Plant Interlocks |
Cabling & Field Installation Requirements
To preserve signal integrity and ensure operational safety under fire conditions, field cabling must meet specific conductor cross-sectional areas. Power and start command lines connected to DC+ and DC- require 1.5mm² or above fire-rated cable. All secondary field circuits—including solenoid terminals J11/J12, pressure switch inputs K11/K12, feedback connections YK1/YK2, and auxiliary contacts COM/NO—must be wired using 1.0mm² or above fire-rated cable, conforming to all applicable local fire installation codes.
Enclosure, Base Mounting & Environmental Tolerances
The C-9329 module features a modular plug-in design where the white (RAL9016) ABS body simply plugs onto the base after field cabling is terminated. Physical and environmental compatibility parameters include:
- Mounting Compatibility: Standard 65mm mounting hole pitch distance for seamless surface box or enclosure mounting.
- Physical Footprint: 120mm × 80mm × 43mm overall dimensions with a total assembly weight of 188g (including base).
- Environmental Range: Rated for ambient operating temperatures from -10°C to +50°C and relative humidity levels up to 95% (non-condensing), suitable for indoor control rooms, plant areas, and clean-agent cylinder storage banks.
