1.4.5.6 TR CU/EAC
The 40/40I Flame Detector is in compliance with the standard TR CU
012/2011 per:
1Ex d e IIC T5 Gb X
Ex tb IIIC T96°C Db X
– 55°C ≤ Ta ≤ +75°C
or
1Ex d e IIC T4 Gb X
Ex tb IIIC T106°C Db X
– 55°C ≤ Ta ≤ +85°C.
For more details, see TR CU certificate No. Т R CU C- US.МЮ62.В.04333.
1.5 Performance Considerations
This section describes performance aspects of the 40/40I and includes:
 Detection Sensitivity, page 21
 Cone of Vision, page 22
 False Alarm Prevention, page 24
 Visual Indicators, page 25
 Output Signals, page 26
 Detector Status, page 27
 Auxiliary Relay as End-of-Line, page 28
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).
1.5.1.1 Standard Fire
Defined as a 1ft
2
/0.1m
2
n-heptane pan fire, with maximum wind speed of
6.5ft/sec / 2m/sec.
1.5.1.2 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.
