Integrated System Test (IST)

Integrated System Testing (IST) — a critical validation process that ensures all electrical, safety, and mechanical systems in a facility operate together seamlessly under real-world conditions. Our IST services verify the complete integration and performance of systems such as Fire Alarm Systems (FAS), VESDA, Gas Suppression Systems (GSS), Transformers, Diesel Generators (DG Sets), Automatic Transfer Switches (ATS), UPS, Inverters, CRAC and PAC Units, ensuring they respond and recover as designed during normal and emergency scenarios.

Why Integrated System Testing Is Crucial

1. ✅ Confirms that all systems interact correctly during power failures, fire incidents, or critical events
2. ✅ Detects integration gaps between electrical, safety & HVAC systems
3. ✅ Enhances system uptime, operational continuity & occupant safety
4. ✅ Meets compliance requirements for Green Buildings, LEED, and critical infrastructure commissioning
5. ✅ Builds confidence before handover or Go-Live
