2. Functional description

An optical method is used for the detection of visible smoke. When the concentration of smoke in the optical

chamber exceeds a given threshold, an alarm is triggered. The smoke sensor operating parameters are

modified depending on the temperature changes recorded by the heat sensor (thermistor).

The heat sensor operates according to the requirements of Class A1R (EN 54-5). The alarm will be triggered

after exceeding a certain threshold temperature (54°C - 65°C) or in the event when the temperature rises too

rapidly (see Table 1).

If the event of an alarm, the detector output is activated and the LED lights up.

3. Installation

The detector is designed for indoor installation. In its typical applications at home or in office, the detector

should be installed on the ceiling, at a distance of at least 0.5 meters from the walls or other objects.

Do not install the detector in places with high concentration of dust and/or formation and

condensation of water steam.

The detector should not be mounted in the vicinity of heaters and cookers.

Disconnect power before making any electrical connections.

1. Remove the plastic dust cap.

2. Turn the cover counter-clockwise (Fig. 5) and remove it (Fig. 6).

3. Using wall plugs (screw anchors) and screws, fasten the enclosure base to the ceiling.

4. Using DIP-switches, configure the detector appropriately (see: C

ONFIGURING THE DETECTOR

5. Screw the wires to the corresponding terminals in the enclosure base (see: C

ONNECTING WIRES

6. Replace the detector cover and turn it clockwise.

7. If any other operations which may cause contamination of the optical chamber are being carried in the

facility where the detector is installed, the detector must be temporarily covered with a plastic dust cap.

Note: It is recommended that the dust cap be kept in case of conducting any repair work in the future.

Table 2. Configuring the detector operating parameters with the DIP-switches shown in Fig. 1.

If the alarm memory is disabled, the detector will keep signaling the alarm until the alarm cause no longer exists.

After the alarm memory is enabled, the detector will keep signaling the alarm until it is reset (power reset).

If both smoke detection and heat detection are disabled, the detector will signal a configuration error by LED

blinking.

Table 3. Setting the DIP-switches shown in Fig. 2 for an appropriate configuration of the output.

In the double EOL configuration, two 1.1 kresistors are used. The double EOL configuration makes it possible

for the control panel to signal detector tamper if the cover is removed or the wires are cut off.

3.2 Connecting wires

The terminals located in the enclosure base are designated with numbers:

1 – common ground;

2 and 3 – alarm output;

4 – power input +12 V DC;

5 – additional terminal.

Shown in Figs 3 and 4 are examples of how the detector can be connected to the control panel (OUTx – power

output; COM – common ground; Zx – zone programmed as fire; Zy – zone programmed as tamper). In the

example shown in Fig. 4, the additional terminal is used to connect the tamper circuit (the interruption of which

will trigger a tamper alarm).

4. Cleaning the optical chamber

The detector monitors the state of the optical chamber. Deposition of dust in it may result in malfunction of the

detector. It is recommended that you clean the optical chamber at least once a year. Cleaning the chamber is

necessary, when the LED indicates contamination of the chamber (one flash every 30 seconds). In order to

clean the chamber:

1. Turn the cover counter-clockwise (Fig. 5) and remove it (Fig. 6).

2. Pull aside the mounting catches (Fig. 7) and remove the electronics board with the optical chamber (Fig. 8).

3. Remove the cover from the thermistor (Fig. 9).

4. Pull aside the thermistor and its leads (Fig. 10).

5. Pull aside the mounting catch of the optical chamber (Fig. 11) and remove it (Fig. 12).

6. Using a soft brush or compressed air, clean the labyrinth in the cover and the base of the optical chamber,

paying attention to the recesses where the LEDs are installed.

7. Replace the cover of the optical chamber.

8. Place the thermistor leads in the respective grooves.

9. Replace the thermistor cover.

10. Secure the electronics board with the optical chamber in the cover mounting catches. The board must be

mounted so that the LED coincides with the light guide.

11. Replace the detector cover and turn it clockwise.
