Speech intelligibility measurements using STIPA, fault analysis and commissioning support for type A evacuation alarm systems. EvacSafe records the results in an analysis or measurement report tailored to your question.
Discuss your needsIs the fire alarm difficult to hear in an enclosed office, phone booth or quiet workspace? EvacSafe helps define the measurement task and investigate evacuation alarm sound levels at agreed locations. We first agree on the system type, design requirements, measurement conditions and operation of the alarm. A sound level measurement examines loudness; a STIPA measurement examines the intelligibility of spoken messages. The required assessment depends on the room and the applicable design criteria.
An audible message is not always intelligible. STI or STIPA measurements assess speech transmission. Before measuring, we agree the assignment, relevant spaces, ambient noise and assessment framework. Results remain linked to the conditions in which they were measured.
For a complex system fault, we first organise messages, previous work and available installation data. During commissioning or functional testing, we agree which functions and signal paths will be examined. You receive traceable findings and recommendations for repairs or further investigation.
We agree the spaces, measurement positions, signal path, system settings and representative operating conditions in advance. Share the programme of requirements, loudspeaker plans and previous measurement reports where available. The report links STI results to positions and conditions and identifies limitations and any next steps, making the measurements and basis of assessment clear.
The price depends on the measurement task, number of rooms and measurement positions, available documents, access times and required report. Send a floor plan, the number of phone booths or rooms and the design requirements if available. Please also state who can activate and reset the system. You will receive a proposal specifying the agreed work and deliverable.
