1.2 Design
The PolyRex detector DOTE1152 is installed in a modern, attractive, impact–resi-
stant plastic housing that fits unobtrusively into any room architecture. The detector
is secured in the interactive DB1151 base with a vibration–proof bayonet fitting. Ex-
cept for the identification module that defines the installation location at the time the
system is commissioned, the base does not contain any electronic components.
The detector is equipped with a response indicator (red LED), to indicate alarm. Acti-
vated from the control unit, the response indicator can also be programmed to pro-
vide information for servicing purposes. The detector is equipped with an output for
connecting an external response indicator. This indicator is normally assigned to the
connected detector, but it can also be assigned programmatically to any detector wit-
hin the same object.
The detector is fully electronic and has no wearing parts. As protection against envi-
ronmental influences the electronic circuitry is shielded and the circuit board is
coated with a special protective varnish. For periodic factory overhaul the protective
hood and grille can be removed.
The DB1151 detector base can either be flush mounted directly on a recessed box in
the ceiling, or surface mounted with the DBZ1191 base attachment. It is connected to
the control unit via a two–wire line. Spring terminals are provided for wiring the base.
Efficient installation, removal and testing of the detector is possible by means of the
DZ1191 detector extractor, the RE6 detector tester and the DZ1193 opto-electronic
detector exchanger and tester. The response behaviour of the detector to CO gas
can be tested with the DZE1152 CO detector tester. If an extension rod is used, work
up to a ceiling height of 7 m can be performed without any further tools. A compre-
hensive range of base accessories is available for special applications such as in-
stallation in humid environments, protection against unauthorized removal, etc.
The DOTE1152 is provided with a line isolation function.
As a distinctive feature, the DOTE1152 detector is marked with a yellow circle which
is visible when the detector is installed.

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).

3 Design
The core of the PolyRex detectors DOTE1152 is a high–quality, opto-electronic mea-
suring chamber, hat screens off extraneous light but optimally detects light–coloured
and dark smoke particles. The light source, the light stop and the light receiver are
aranged in such a way that the light rays from the source cannot directly reach the
receiver (Fig. 1 und Fig. 2). Only when smoke particles are present in the path of
rays does some of the scattered light reach the receiver and produce an optical si-
gnal.
The temperature sensor (NTC) is located in the detector dome.
The electrochemical CO gas sensor is installed on a sub print. This sub print with the
sensor is mounted and fixed through an opening in the cover on the detector base
side.
Due to their optimized optical system, the temperature sensors installed in a protec-
tive envelope, shielded electronics and special circuit board coating, these detectors
are highly immune to environmental influences such as temperature, humidity,
corrosion and electrical interference fields (keep to the technical data).
