14.2 Heat Detector Sensitivity Settings
Heat Detectors can be set in two modes:
 Fixed temperature – The alarm point can be set between 50°C – 90°C in steps of
1°C.
 Rate of rise – The detector will alarm when the rate of temperature rise is equal or
higher than the setting in the Sensitivity Field, in the range of 7°C/minute –
13°C/minute in 1°C/minute steps.

Please note:
Configure the heat detector as Rate of Rise in the range of 8-13°C per minute
or as Fixed Temperature in the range of 58-70°C to comply with UL 521.
14.3 Multi-Sensor Detectors Sensitivity Setings
A smart algorithm is used by the TPH-482A’s powerful processor to analyze the ambient
temperature, its rate of rise and the trend of these parameters. It then passes a value to
the control panel.
Set the detector’s sensitivity between 2 (most sensitive) and 10 (least sensitive).
