Classifying detector temperature
Detectors will conform to one or more of the following
classes: A1, A2, B, C, D, E, F or G. Optionally,
manufacturers may give additional information concerning
the response type exhibited by the detector, by adding the
suffix S or R to the above classes. Detectors, with a suffix
S to their class, do not respond below the minimum static
response temperature, even at high rates of rise of air
temperature. Detectors, with a suffix R to their class,
incorporate a rate of rise characteristic, which meets the
response time requirements for high rates of rise of air
temperature, even when the air temperature starts
substantially below the typical application temperature
(EN54-5:2000).
Processing for Warning/Delay to alarm section
This section determines the actions the control panel
performs when the device threshold exceeds.
 Use zone settings: The detector uses the
parameters of the assigned zone; if this option is
disabled, you can manually select the Warning or
Delay to alarm time.
 Delay to alarm: The control panel will activate the
Alarm delay.
 Warning: The control panel will activate a
Warning signal.
Depending on the detector in question, smoke, heat,
smoke and heat, heat and carbon monoxide (CO), smoke
