4.4.2. The detector operates under a polling loop controller in accordance with operation conditions
defined in the PL controller configuration with the help of UProg. In UProg define the type of the
addressable device for the detector and set its Input Type to the value 3, Heat Fire. Also select the
value 2, Controlled by the S2000-KDL for the parameter Device Indication Control. Please refer to the
PL controller User’s Manual and UProg documentation to read more about selecting the type of
addressable devices and configuration parameters. Setting detector’s addresses is described in
Section 6.1 of this manual.
4.5. Mounting Location Considerations
4.5.1. While considering mounting locations for the detectors please follow the Russian regulations
SP5.13130 (Section 13).
4.5.2. The transmitter/receiver unit and the reflector (reflectors) shall be placed opposite to each other.
It is necessary to select the proper number and the proper type of reflectors. If one reflector of XS
(Extra Small) Type is used then the detector is guaranteed to align in the range of monitored distances
5 to 15 m, for one reflector of S (Small) Type the range is 15 to 60 meters, for one reflector of L
(Large) Type the range is 20 to 80 meters, for two reflectors of L Type the range is 24 to 100 meters,
and for four reflectors of L Type the range is 30 to 120 meters. As many reflectors as required with
necessary types are supplied with the detector (see Section 3). It should be taken into account that if for
a certain distance the detector can normally align with a different number of reflectors (for example,
for a distance of 40 m) then its immunity to interference will be higher when the number of reflectors
are more. This is due to the lower value of the required gain and thus to lower sensitivity to external
electromagnetic and optical interference.
4.5.3. In accordance with actual regulatory documents the maximum possible width of area protected
by a single detector is 4.5 meters on both sides of line of sight.
4.5.4. No minimum distance between lines of sight of two adjacent detectors is regulated, but it
should be borne in mind that when detectors are closely to each other they will partially reflect the
beams of each other. This doesn’t affect smoke detection but while testing the detector’s sensitivity it
is necessary to obscure a part of the reflected surface of not only its own reflector but also of adjacent
ones hitting the zone of detection pattern of the transceiver.
4.5.5. The sensitive elements of the transceiver unit should be protected against direct sunlight or
other powerful light sources (such as spotlights) which have a very powerful infrared component in
their radiation spectrum. To achieve this, the minimum required angle between the line of sight and
sunlight rays falling on the transceiver unit / reflector should be at least 10 degrees.
4.5.6. To minimize effect of lighting devices on the detector operation, it is advised to position the
transceiver as far from such devices as possible taking into account that the more the distance between
the transceiver and the reflector, the greater the influence of interfering optical radiation (due to higher
value of the gain selected during alignment).
4.5.7. The detector should be mounted to stable structures (brick walls, reinforced concrete walls,
support columns, etc.) that are not expected to experience movement, vibration, or deformation. If
unable to place the detector on rigid structures, then while mounting it to light wall panels the detector
should be attached as close to the places of fastening the panels to wall studs as possible in order to
minimize the effect of their movement on the detection pattern of the optical system. If there is a
choice, the transceiver unit should be mounted to the stable surface and the reflector should be
mounted to the less stable surface.
4.5.8. While mounting single-ended detectors which the S2000-IPDL is related to it should be taken
into account that their performance is highly dependent on stray reflections. The typical things
