2. Description

Smoke detection

An optical method is used for detecting visible smoke. When the concentration of smoke in the optical chamber exceeds a given threshold, an alarm is triggered. The smoke sensor's operating parameters are modified based on temperature changes recorded by the heat sensor (thermistor). The detector automatically compensates for gradual changes in the optical chamber caused by dust deposition.

Heat detection

The heat sensor operates according to the requirements of Class A1R (EN 54-5). An alarm is triggered when the temperature exceeds 54°C or if there is a too fast temperature rise, as detailed in Table 1.

Alarm signaling

In the event of an alarm, the detector's output is activated, and the LED lights up.

Alarm memory

If alarm memory is disabled, the detector signals the alarm until the cause no longer exists. If alarm memory is enabled, the detector signals the alarm until it is reset (e.g., by power reset).

Alarm output

The detector features a relay output activated during an alarm. The relay contacts can be selected as normally open (NO) or normally closed (NC) in the normal state. When connecting to a SATEL control panel, the detector's built-in EOL resistors (2 x 1.1 kΩ) can be used. The control panel input should be programmed as 2EOL. Removing the detector's cover or cutting wires in this configuration will trigger a tamper alarm.

Detection of optical chamber soiling

The detector monitors the optical chamber's condition. Dust deposition can lead to malfunctioning. When the optical chamber requires cleaning, this state is indicated by the LED.

LED indicator

The red LED indicates:

• Alarm: ON
• Optical chamber soiling: one flash every 30 seconds
• Incorrectly configured settings: flashing

3. Selecting a Mounting Location

The detector is designed for indoor installation.

• Install the detector close to the building/apartment exit (e.g., in the hall or lobby). Refer to Figures 1 and 2 for typical placement.
• For typical home or office applications, install the detector on the ceiling, as close as possible to the center of the room, at least 0.5 meters from walls or other objects. Refer to Figure 3 for correct placement.
• Do not install the detector in areas with high concentrations of dust, or where water steam may form or condense.
• Do not install the detector near heaters, cookers, fans, or air-conditioner outlets.
• Do not install the detector in locations with obstructed airflow (e.g., in recesses or niches).

Diagram Description (Figures 1 & 2): These figures illustrate typical detector placements in residential layouts. Detector placement is indicated by numbered circles: 1 - living room, 2 - room, 3 - hall/lobby, 4 - kitchen, 5 - basement. Different locations are marked as basic or additional for detector installation.

Diagram Description (Figure 3): This figure shows correct and incorrect detector placement relative to walls. A green checkmark indicates correct placement at least 0.5 meters from a wall, while a red cross indicates incorrect placement too close to a wall.

4. Installation

Disconnect power before making any electrical connections.

1. Remove the plastic dust cap.
2. Turn the cover counter-clockwise and remove it. (Refer to Figures 8 and 9 for removal steps).
3. Secure the enclosure base to the wall using appropriate wall plugs (anchors) and screws, selected for the specific mounting surface (e.g., concrete, brick, plaster).
4. Configure the detector using the DIP-switches. Refer to the "Configuring the detector" section.
5. Connect the wires to the corresponding terminals in the enclosure base. Refer to the "Connecting wires" section.
6. Replace the detector cover and turn it clockwise.
7. If work is being carried out in the premises that may cause soiling of the optical chamber, cover the detector with a plastic dust cover and leave it until the work is finished.

? It is recommended to keep the dust cap for future repair work.

Diagram Description (Figures 8-15): These figures illustrate the physical steps for installation and maintenance, including removing the detector cover, releasing and removing the electronics module, removing the optical chamber cover, and removing the thermistor element.

4.1 Configuring the detector

Detector settings are configured using the DIP-switches shown in Figures 4 and 5.

? If smoke detection and heat detection are disabled, the detector's LED will flash to indicate an error.

4.2 Connecting wires

The terminals in the enclosure base are numbered:

• 1: common ground
• 2 and 3: alarm output
• 4: power input +12 V DC
• 5: additional terminal

Figures 6 and 7 show examples of connecting the detector to a control panel. (OUTx – power output; COM – common ground; Zx – zone programmed as fire; Zy – zone programmed as tamper). In Figure 7, the additional terminal (5) is used to connect the tamper circuit; interrupting this circuit triggers a tamper alarm.

Diagram Description (Figures 6 & 7): These diagrams illustrate wiring configurations. Figure 6 shows connections without EOL resistors, while Figure 7 shows connections with EOL resistors (2EOL) and a tamper circuit connection to a control panel.

5. Maintenance

The detector should undergo regular checks for correct functioning. Periodic checks should be performed at least every 6 months.

6. Cleaning the optical chamber

It is recommended to clean the optical chamber at least once a year. Cleaning is necessary when the LED indicates chamber fouling (one flash every 30 seconds).

1. Turn the cover counter-clockwise and remove it. (Refer to Figures 8 and 9).
2. Pull the release lever to unlock the electronics module and turn it counter-clockwise. (Refer to Figures 10 and 11).
3. Remove the electronics module with the optical chamber. (Refer to Figure 12).
4. Remove the plastic element with the thermistor from the optical chamber cover. (Refer to Figure 13).
5. Release the mounting catch and remove the optical chamber cover. (Refer to Figure 14 and 15).
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 optical chamber cover.
8. Replace the plastic element with the thermistor on the optical chamber.
9. Secure the electronics module with the optical chamber in the cover and turn it clockwise.
10. Replace the detector cover and turn it clockwise.
