Performance Considerations
This section describes performance aspects of the 40/40UFI.
2.5.1
Detection Sensitivity
Detection sensitivity is the maximum distance at which the detector reliably
detects a specific size of fire and typical type of fuel (standard fire).
2.5.1.1
Standard Fire
Defined as a 1ft
2
/0.1m
2
n-heptane pan fire, with maximum wind speed of
6.5ft/sec / 2m/sec.
2.5.1.2
Sensitivity Ranges
The detector has 4 user-selectable sensitivity ranges. For each range there are 2
response levels:
•
Warning (Pre-alarm)
•
Alarm
The detection distance for the warning level is approximately 10% higher than for
the alarm distance.
Alarm response times for a standard fire at a specified range are shown Table 2.

For some typical ambient conditions the Zeta parameter as defined in NFPA 72
for the detector is 0.005 (1/m).
Note:
Zeta parameters may vary significantly with changes in temperature,
air pressure, humidity, visibility conditions, etc.
2.5.1.3
Other Fuels
The detector reacts to other types of fire as follows:
