| Terminal Label | Typical Function | State (Armed/Normal) | State (Fire/Actuated) | | --- | --- | --- | --- | | SW1 - COM | 24VDC+ from panel | 24V present | 24V present | | SW1 - NO | Shunt trip gas solenoid | Open (0V) | Closed (24V) – Gas off | | SW1 - NC | Exhaust fan run signal | Closed (24V) | Open (0V) – Fan stops | | SW2 - COM | Building FACP common | Reference | Reference | | SW2 - NO | Alarm relay to panel | Open | Closed – Send signal |
Wiring should be installed alongside original equipment manufacturer (OEM) looms and secured at regular intervals to prevent heat and abrasion damage.
To ensure the system remains reliable under heavy vibrations or heat: Standard Compliance : All wiring must adhere to AS5062-2016 standards for mobile and transportable equipment. Protection
Is the QTec control head (typically 24VDC) or non-power-limited (120VAC direct)? Most modern diagrams show a listed power supply. Do not mix voltages. Keep 120VAC wiring separate from low-voltage signal wiring.
This comprehensive guide dives deep into the intricacies of wiring Qtec suppression systems. We will explore the components, decipher standard wiring configurations, highlight safety protocols, and troubleshoot common issues.
