shown on Figure 1 Annex 3. The wiring diagram for the detector to 2-wire DC FACP is shown
on Figure 2 Annex 3. The wiring diagram for the detector to 4-wire intruder fire alarm control
panel with the help of MUSH-DL module is shown on Figure 3 Annex 3. The wiring diagram for
the detector to 4-wire AC fire alarm control panel with the help of MUSH-DL module is shown
on Figure 4 Annex 3.
5 HOW TO PREPARE THE DETECTOR FOR OPERATING
5.1 After receiving your detector it should be unpack and the kit’s content should be
checked. Allow the detector to stay packed in the room for at least 4 hours if the detector was
exposed to negative temperatures before opening. Inspect the exterior. Make sure that seals are
intact and not visibly damaged (cracks, dents). If the detector was damaged while shipped or not
operates properly, report the manufacturer within 5 days.
5.2 Checking the receiver for proper operation
5.2.1 Set The CALIBRATION and RANGE switches on Rx to «1» position.
5.2.2 Connect Rx to a 20-30 V DC power source as shown on Figure 1a Annex 3. When
the transmitter is off, both LEDs on Tx shall flash during 10 s at different intervals between
flashes (0.5 sec and 2 sec).
5.2.3 Set the RANGE switch to «0» position. The state of LEDs shall not change.
5.2.4 Set both switches to «0» position. The left LED of the transmitter shall be lit in 10
sec.
5.2.5 Disconnect the transmitter from the power supply source.
5.3 Checking the transmitter for proper operation
5.3.1 Connect the transmitter to a 20-30 V D.C. power source as drawn on Figure 1b
Annex 23 through the 51 Ohm series resistor in plus wire. Both LEDs shall synchronically flash
10 times once every 1 sec.
5.3.2 Disconnect the transmitter from the power supply.
6 INSTALLATION
6.1 The installation should be made according to a pre-elaborate plan where the
requirements of the manual should be considered.
ATTENTION: Only one detector should be connected to a fire alarm loop. It is
recommended to make connections of a control panel with the transmitter and the receiver
with the transmitter by twisted-wire cable and lay in the special earthed cable channels.
Shielded cable should be used to provide additional protection against electrical obstacles.
It is not recommended to place fire alarm system cables in common cable channels with
other electrical wires.
6.2 It is not recommended to mount the units in places where the gases, vapour and
aerosols can cause corrosion. During repair works additional cover should be used to protect units
against debris.
6.3 The detector’s sensitive zone is the infrared beam between the receiver and transmitter.
The sensitive zone diameter is determined by the optical system window. The sensitive zone
should not be overlapped by any objects.
6.4 The direct light exposure of the optical system window is not allowed.
6.5 Units of detectors should be installed to a rigid base (main wall, column, rafter etc.) in
an accessible place.
Note: It is allowed to install several detectors in one room allocating sensitive zones
parallel to each other. When the distance between parallel optical axes of sensitive zones is less
than 3 meters, different detector units should be mounted on the same wall: transmitter, receiver,
transmitter and so on.
6.6 Mark out the transmitter and receiver mounting places according to Annex 1.
6.7 Unscrew the waterproof covers with a special key and secure the baseplates of the
receiver and transmitter using brackets.
6.8 Connect to a control panel according to Figure 2, Figure 3, Figure 4 Annex 4 depending
on the control panel type. Bring wires through the opening in the stub and connect them with
screw block contacts.
6.9 Seal the openings (with wires) and threaded coupling in the stub with some silicon
sealant.
7 ALIGNMENT AND CHECKING FOR PROPER OPERATION
7.1 Adjustment
7.1.1 Loose Rx and Tx bracket attaching screws, direct the optical system windows to
each other.
7.1.2 Tighten screw joints with force ensuring the fixation of the units’ chosen position
and possibility of the following adjustment.
7.2 Calibration
7.2.1 The RANGE switch on Rx unit sets the distance between Tx and Rx. The RANGE
switch should be set to «0» if the distance between the units is up to 30 m. When the distance is
greater than 30 m - to «1» position.
7.2.2 Set the CALIBRATION switch on Rx to «1» position.
7.2.3 Turn the fire alarm system on. The voltage drop on the EUI-1 contacts «7» and «8»
should not be less than 8 V. In 10 sec after energizing both LEDs will simultaneously flash on Tx
every 1 sec.
Depending on the adjustment precision, the following combinations of optical indication
on Rx are possible:
- bright flashes every 1sec when high level of optical signal has been detected;
- low brightness flashes of the left indicator every 1 sec and right indicator is off when
normal level of optical signal has been detected;
- bright flashes of the right indicator and low brightness flashes of the left indicator
every 1 sec when low level of optical signal has been detected;
- bright flashes of both indicators every 0.5 sec when adjustment of the receiver and
transmitter has been made incorrectly
- flashes at different intervals (0.5 sec and 2 sec), and a control panel will fix open-
circuit in alarm loop when the electric connection between the receiver and transmitter is absent.
7.2.4 If the optical signal level is high it is necessary to attain the normal signal level by
slowly turning the calibration regulator counter-clockwise. It is allowed to change the RANGE
switch from «1» to «0» if necessary.
7.2.5 If the optical signal level is normal it is necessary to set the high level of signal
slowly turning the calibration regulator clockwise and then to set again the normal level of signal
slowly turning the calibration regulator counter-clockwise.
7.2.6 If the optical signal level is low it is necessary:
- set the normal level of signal turning the sensitivity adjustment screw clockwise;
- set the high level of signal turning the sensitivity adjustment screw clockwise;
- set the normal level of signal turning the sensitivity adjustment screw counter-
clockwise.
When the normal or high signal level can not be set with the sensitivity adjustment screw,
it is necessary to check the RANGE switch position and mechanically adjust the receiver and
transmitter again.
7.2.7 Attain the optimal coaxiality of the optical system windows’ axes of the receiver
and transmitter, when any their deviation in horizontal and vertical planes only leads to optical
signal level decrease. Return the unit to the position corresponding to normal signal level.
7.2.8 If any deviation of the receiver or transmitter leads to optical signal level increase,
it is necessary to fix the unit’s position, to set the normal signal level with the calibration
regulator. Then repeat the previous action.
7.2.9 Tighten attachment screws of the receiver and transmitter to brackets. The status of
the receiver’s indicators should not change.
7.2.10 Calibrate the detector attaining the normal signal level, turning the calibration
regulator counter-clockwise and set it to the position near the indicators’ switch from the normal
signal level mode to the low one.
7.2.11 Set the CALIBRATION switch on the receiver unit to «0» position. The left
indicator on the receiver should flash with low brightness every 1 sec. The right indicator of the
receiver should be off.
7.3 Verification of fire alarm system
7.3.1 De-energize the loop for not less than 5 s. After power supply was restored in not
more than 10 s the detector shall go to the standby mode of operation.
7.3.2 Obscure infrared beam between the receiver and transmitter with a partition, opaque
for infrared light. In 5 sec after the fixation of the partition the left indicator of the receiver will
turn on for about 5 sec. During this time the current consumption will increase by 25±5 mA which
the control panel will interpret as a SHORT-CIRCUIT message. If the power of the loop will be
off then in 5 sec the detector will automatically go to the standby mode. If within the next 5 sec
the partition will not be removed out of the sensitive zone, the detector will go to the fire mode.
7.3.3 Remove the partition from the sensitive zone and de-energize the loop for at least 5
sec.
7.3.4 Energize the loop. The standby mode will be set in 10 s.
7.3.5 Place the 1 dB optical attenuator for at least 15 sec in the in immediate proximity
(not greater than 2 cm) to the optical system window of the receiver. The detector shall remain in
the standby mode.
7.3.6 Remove the 1 dB optical attenuator and in the same way set the 2 dB optical
attenuator. The detector will go to the pre-alarm mode, with both indicators flashing on the
receiver once every 1 sec 5 times. The brightness of the left indicators flashes will be lower than
those of the right one. After that the detector will go to the fire mode.
7.3.7 Deenergize the loop for at least 5 sec.
7.3.8 Energize the loop. The standby mode shall be set in 10 s.
7.3.9 When the infrared beam is totally obscured between the receiver and transmitter for
at least 5 sec, the detector will remain in the standby mode. If the obscuration of infrared beam
remains for more than 5 sec but less than 15 sec, the detector in 5 sec will go to the fault mode for
(51) sec and issue the SHORT-CIRCUIT message to the loop and again go to the standby mode.
If the obscuration of infrared beam remains for more than 15 sec, the detector issues the FIRE
message in the loop.
7.3.10 Screw tightly the waterproof covers of Rx and Tx.
8 MAINTENANCE
Detector should be checked for proper operation periodically at least once every 6 months
in accordance with p.7.3. When the CALIBRATION switch on Rx is in position “1”, the detector
should stay in standby mode. If the mode of indicators changes calibration should be made
according to p.7.2.
9 WARRANTY
9.1 The detector is warranted by the manufacturer for 18 months upon the date of the
detector’s commissioning but not more than for 30 months from the date of approval by the
quality control department of the manufacturer.
9.2 The manufacturer repairs or replaces detectors within the guarantee term provided that
the rules of installation, timely maintenance, transportation and storage of detectors have been
kept.
9.3 In the case that faults according to the reclamation have been removed the guarantee
term is prolonged for the while detectors were not in use because of faults.
