Fire Suppression Wiring Diagram [portable]: Qtec

Qtec systems, such as those using the AFSCP MK2 or Muirhead Fire System Status Panel, generally follow a standardized color-coded wiring scheme to ensure reliability and ease of troubleshooting. Wire Color Description Earth / Ground 0V connection to the vehicle chassis. Orange Battery +VE Constant power input (typically 8 to 35V DC). Red Ignition Input Monitors the vehicle's ignition state. Grey Cylinder Pressure OK Normally closed input; opens if pressure is low. White System Discharge Normally closed; opens when the cylinder discharges. Yellow/Blue Run Solenoid Output 5A continuous output for the engine run solenoid. Green Fault Alarm 1A continuous output for external fault alerts. Purple Aux Output Operates opposite to the ignition output. Core System Components

Wiring should be installed alongside original equipment manufacturer (OEM) looms and secured at regular intervals to prevent heat and abrasion damage. qtec fire suppression wiring diagram

The diagram solves all three by showing you exactly what voltage (typically 24VDC or 120VAC), what contact type, and what sequence is required. Qtec systems, such as those using the AFSCP
