Sayfayı Yazdır6.1 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;
