6.6 The receiver optical unit exposure to direct sunlight, powerful light sources
or other infrared radiation sources should be excluded.
6.7 Several IPDL-Ex with parallel monitored zones may be installed in a single
premise, opposite operation of neighboring receivers and transmitters is permitted.
Whereupon distances between two neighboring IPDL-Ex must be maximum 9 m
and minimum:
a) 5 m – if the distance between the TM and the RM is 50 to 150 m;
b) 2.5 m – if the distance between the TM and the RM is 8 to 50 m.
6.8 The IPDL-Ex should be installed at 0.3 to 0.6 m distance from ceilings. In case
the premise height is greater than 12 m, the IPDL-Ex should be installed in two tiers.
6.9 IPDL-Ex Installation Procedure:
- mark out the TM and the RM installation points at the same distances from
the ceiling and the nearest wall or beam (the angle between the TM and the RM
base planes must not exceed 6.5 degrees);
- remove covers from modules by pressing the latches with a screwdrivers
through an opening near the LED indicator and simultaneously pulling the cover
away;
- fasten the TM and the RM bases tightly to the wall or timber without changing
positions of optical units;
- connect power supply lines and Al1 and Al2 alarm loops to the TM and the
RM terminal blocks;
- if necessary, connect the OAED to the TM («+K
»
connect to «+OAED
»
,
«-K
»
– to «-OAED
»
).
6.10 Depending on the alarm loop power supply circuit, set the switch «P»
located on the TM PCB in the following positions:
- DIP-switch 2 «P
»
in ON position – normally opened Al2;
- DIP-switch 2 «P
»
in OFF position – normally closed Al2.
6.11 Adjust the operating threshold needed for the premise by means
of 3, 4 DIP-switches «THRESHOLD
»
as per Table 4. In case IPDL-Ex is installed in
premises with gassed air (in garages, hot shops, etc.), the threshold value should
be increased, and vice versa, in the gas free premises where low concentration
of smoke is an attribute of a fire the threshold should be reduced.
7 IPDL-Ex Adjustment
7.1 The IPDL-Ex constancy of performance largely depends on it’s adjustment,
therefore, it should be performed especially thoroughly.
7.2 Firstly, the TM and the RM EI optical units axes should be aligned as close
as possible by means of their adjustment.
7.3 Adjust the RM optical unit in the following way:
- put 1 and 2 DIP-switches on the RM PCB in the positions corresponding to the
distance between the TM and the RM (the positions of DIP-switches depending
on the distance are listed in Table 3);
- look in the mirror located at the top of the TM base and change the sight angle
until the cross (the point on the mirror) is superimposed onto the image of the RM;
- superimpose the sight of the TM optical unit onto the cross without changing
the vertical and the horizontal sight angles with adjustment screws;
- the optical diagram of adjustment is shown in Figure 2.
7.4 Execute the RM adjustment:
- look in the mirror located at the top of the RM base and change the sight angle
until the cross (the point on the mirror) is superimposed onto the image of the TM;
- superimpose the sight of the RM optical unit onto the cross without changing
the vertical and the horizontal sight angles with adjustment screws;
- any foreign objects and IR radiation sources (space heaters, welding units,
etc.) emergence in the IPDL-Ex operation zone during adjustment procedure
IS PROHIBITED;
- energize the IPDL-Ex;
- set «A
»
DIP-switch 1 in he ON position - the RM turns to adjustment mode;
- monitor the signal level by HL1 – HL5 LED indicator:
- red HL1 LED indicator lighting means no signal;
- green HL2 – HL5 LED indicators lighting display signal level (the stronger the
signal, the more indicators are lighting);
- frequent blinking of all HL2 – HL5 indicators means that the signal is above
normal at minimum gain level – it is possible in case the TM transmission power
is incorrectly chosen or the distance between the TM and the RM is too small;
- achieve the maximum signal level (indicated by the number of lit HL2 – HL5
indicators) by means of adjusting screws;
- the signal level may be evaluated more precisely by readings of a voltmeter
connected to the «-K+
»
terminal block, whereupon the readings should be as close
to IPDL-Ex power supply voltage as possible;
- for fine adjustment after performing the two previous steps, the TM adjustment
should be repeated and the maximum signal level obtained with the help of
adjusting screws;
- close the TM cover and return to the RM adjustment;
- put DIP-switch 1 «A» into the OFF position, whereupon the IPDL-Ex is finishing
adjustment and assigns the time for installing the cover and fine adjustment with
regard for signal loss with the light filter;
- the time allowed for the cover installation is displayed by means of the HL1
LED indicator: for 35 s, HL1 blinks at 4 Hz frequency, then for 15 s, at 10 Hz,
during this time, the IPDL-Ex cover should be installed;
- upon expiry of the time allowed, the RM completes adjustment and switches
to a standby mode displayed by HL1 LED blinking at 5 s intervals;
- it is prohibited to de-energize IPDL-Ex and to cover the transmitter and the
receiver lenses during the period of time from the moment of the cover installation
till the IPDL-Ex changes to a standby mode. Presence of foreign objects into the
IPDL-Ex operation zone should be excluded as well;
- after IPDL-Ex changes to a standby mode, it’s adjustment is considered to
be completed.
8 Functional Check
8.1 IPDL-Ex parameters in a «Fire» message generation mode are tested at
the factory or at specialized laboratories with the application of special technical
facilities during fire tests. IPDL-Ex functional check in the «Fire» message generation
mode should be performed after IPDL-Ex adjustment. under the TM cover removed.
Press and hold down the «TEST» key button on the TM PCB or press and hold
down a «TEST» key button on the TM «TEST» terminal block (in this case, the TM
lid may stay in it’s position). The key button should be held down for at least 5 s,
whereupon the TM HL1 LED indicator should light continuously. BRSS-Ex should
receive a «Fire» alarm message.
8.2 Functional check of IPDL-Ex in a «Fault» message generation mode is
performed as follows.
In case the TM «TEST» key button is held down for more than 10 s, the TM
switches to the fault simulation mode. The TM HL1 indicator blinks at 1 s intervals,
whereupon the RM HL1 indicator also should start blinking at 1 s intervals. A
control panel should receive a «Fault» message. After the TM «TEST» key button
is released, the IPDL-Ex returns to standby mode.
