With the exception of test mode, the parameter sets listed here are arranged in order
of sensitivity (APS216 is the most sensitive).
Note: All values are typical!
Smoke sensitivity: To simplify the comparison of smoke sensitivities between the
parameter sets, we are specifying an AlgoRex smoke sensitivity index.
Please note, that this index is a relative figure. "2" means an increased sensitivity by
a factor of 2 (compared to the parameter set with index "1"); therefore the detector
will alarm at half the smoke density if measured in the CEN smoke tunnel acc. to
EN54.
An AlgoRex smoke sensitivity index of "0" means "no alarm with smoke only".
* The smoke sensitivity of the DOTE1152 changes depending on the temperature
and the CO signal. If CO is detected, the sensitivity level of the detector is increased;
in atmospheres without CO the detector reacts with normal sensitivity.
1)
APS204: In addition, a special filtering method is applied for the detection of de-
ceptive phenomena, also when CO is present. (Priority deceptive phenomenon.)
Under certain conditions, this parameter set does not fulfil the normative require-
ments on test fires according to EN54-7.
2)
APS207: In addition, a special filter is used for the detection of deceptive pheno-
mena if no CO is present. (Priority CO.)
Furthermore, it is possible to use the parameter sets of the DOT1151/52 without CO
signal evaluation (see Technical specification, document no. 1027).
