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

6.5 ft./sec (2 m/sec).

1.5.1.2 Sensitivity Ranges

The detector has four user-selectable sensitivity ranges. For each range
there are two response levels.

WARNING (Pre-alarm)

ALARM

The detection distance, for the WARNING level, is approximately 10% higher
than the ALARM distance.
