Regional Regulatory Requirements and Notices

UL

For open area protection the fire alarm threshold (signal) that initiates an evacuation procedure via the Fire Alarm
Panel must not be set less sensitive than 0.625%/ft. The detector can send this signal via the Fire Alarm Panel
Output signal or the Pre-alarm output signal.

Through validation testing, Underwriters Laboratories Inc. has verified that VESDA ECO gas detectors, when
installed within the sample pipe network, present no significant effects on the smoke detection performance of
VESDA. The use of the ASPIRE2 calculation software is required to verify system design performance with all
devices included in the design.
