ARTON-DL smoke detector

Manual

1 dB attenuator

2 dB attenuator

4.1 The detector is an automatic optical electronic device providing electronic and visual

alarm when smoke appears in the space between Rx and Tx.

4.2 Each unit, transmitter and receiver, is a construction consisting of the housing and a

mounting bracket. To see how the detector is designed please refer to Figure 1 and Figure 2.

Indicators and optical system window are located on front panels of Rx and Tx. The RANGE and

CALIBRATION switches are located on the rear panel of Rx. The slot for access to the sensitivity

adjustment screw is located on the side surface of Rx.

4.3 Rx and Tx units, external interface units EIU-1 are located on the brackets. Rx and Tx

mounting dimensions are shown on Figure 4. The appearance of Tx is shown on Figure 4.

4.4 The wiring diagram for the detector's units operations checking without alignment is

shown on Figure 5. The wiring diagram for the detector to 2-wire DC loop FACP is shown on

Figure 6.

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 5a. 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 5b

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.

6.1 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.
