1.5 Performance Considerations
This section describes performance aspects of the 40/40M and includes:
 Detection Sensitivity, page 20
 Cone of Vision, page 22
 False Alarm Prevention, page 26
 Visual Indicators, page 27
 Output Signals, page 28
 Detector Status, page 29
 Auxiliary Relay as End-of-Line, page 30
1.5.1 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).
Standard Fire
1.5.1.1
Defined as a 1ft
2
/0.1m
2
n-heptane pan fire, with maximum wind speed of
6.5ft/sec / 2m/sec.
Sensitivity Ranges
1.5.1.2
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.
