Mechanical System Interface Test (SIT)
The HVAC Mechanical System Interface Test (SIT) is a critical, full-scope evaluation that ensures your heating, ventilation, and air conditioning systems properly interact with all connected building controls and life-safety components. Unlike a standard HVAC performance check, SIT verifies the communication, responsiveness, and integration of mechanical systems with fire alarms, building management systems (BMS), smoke control equipment, dampers, pressure sensors, and emergency shutdown protocols. This test confirms that every mechanical component not only functions independently but also aligns with the …
