UL and ULC
For open area, open area high velocity and duct protection the fire alarm threshold (setting) that initiates an
evacuation signal must be set such that the sensitivity of each sampling hole is more sensitive than 10%/m
(3.2 %/ft) as determined by the ASPIRE software.
European Installations
The product must use a power supply conforming to EN54: Part 4.
EN 54-20
The product must use a power supply conforming to EN 54-4.
The product is compliant with EN 54-20 sensitivity requirements provided the following conditions are met:
l For a Class A detector, hole sensitivity must be better than 1.5% obscuration/m and transport time less
than 60 seconds
l For a Class B detector, hole sensitivity must be better than 3% obscuration/m and transport time less
than 90 seconds
l For a Class C detector, hole sensitivity must be better than 8% obscuration/m and transport time less
than 110 seconds
These limits should be verified using ASPIRE during the design of the sampling pipe network.
The product is compliant with EN 54-20 flow monitoring requirements provided the following conditions are
met:
l The minor low and minor high flow thresholds should be set at 85% and 115% respectively
l The flow through the detector predicted by ASPIRE must be greater than 20 L/m.
