Apparatus and method for testing a fire suppression system

An apparatus for testing a fire suppression system, the apparatus comprising:

• a blower configured for coupling to an inlet valve of the fire suppression system, the blower configured to provide a supply of pressurized air through the fire suppression system from the inlet valve to one or more outlets of the fire suppression system;
• a sensor arrangement comprising:
• at least one sensor configured for coupling to or operatively associated with one or more of the outlets of the fire suppression system, the at least one sensor of the sensor arrangement configured to measure the pressure of the air at the one or more outlets of the fire suppression system and output one or more output signals indicative of the pressure of the air at the one or more outlets;
• at least one sensor configured for coupling to or operatively associated with the inlet valve to the fire suppression system, the at least one sensor configured to measure the pressure of the air at the inlet valve and output an output signal indicative of the pressure of the air at the inlet valve;
• and
• a communication arrangement configured to convey the one or more output signals from the sensor arrangement to a processing system configured to determine from said one or more output signals indicative of the pressure of the air at the one or more outlets and said output signal indicative of the pressure of the air at the inlet valve the flow rate of the supply of pressurized air at the one or more outlets.
