    Service explanation for JA-150ST

    Wireless combined smoke/heat detector

    This product is part of the JABLOTRON JA-100 alarm system. It provides indoor fire hazard detection. It is not intended for installation in an industrial environment. It contains an optical smoke detector and a temperature sensor. The optical smoke detector is very sensitive to larger particles, which occur in dense smoke, less sensitive to small particles, which are created by burning liquids, such as alcohol. That is why a temperature sensor is also built in, which has a slower response, but is able to detect a fire with a small amount of smoke. The detector responds to the status (it reports activation and also calms down the situation). The product is intended for installation by a trained technician with a valid Jablotron certificate.

    Place detector
    Smoke enters the detector through the flowing air – therefore it must be installed in a location where the air flows well thanks to natural thermal circulation (usually towards the ceiling). The detector can only be used in a closed interior. It is not suitable where the smoke can spread and cool (e.g. high ceilings - more than 5 m) - the smoke will not reach the detector.
    In dwellings, the detector should always be installed in the area leading to the exit (escape route) see Figure 1. If the floor area in the dwelling exceeds 150 m², another detector must be installed there, in another suitable part of the house, see fig. 2.

    It is recommended to install a detector in every room where people sleep.
    Install under horizontal ceilings
    If possible, install the detector in the center of the room. Since a layer of cold air can form near the ceiling, the detectors must not be recessed into the ceiling. The fire detector must never be installed in a corner of the room (observe a distance of at least 0.5 m from the corner of the room, see figure 4). In the corners, the air circulates poorly.

    Install under sloping ceilings
    If the ceiling does not have a suitable flat surface (e.g. an attic room), the detector can be positioned according to Fig. 5.

    Walls, partitions, obstacles, ceilings with bare joists
    The detector must be installed at least 0.5 m from a wall or obstacle. If the room is narrower than 1.2 m, the detector must be installed within the middle third of its width. If the room is divided into sections by means of furniture, scaffolding or half partitions, above which there is not more than 0.3 m from the ceiling, the individual sections should be considered as separate rooms. A free space of at least 0.5 m must be left in all directions under and around the detector. Any irregularity of the ceiling (such as a joist), with dimensions greater than 5% of the ceiling height, are considered to be walls where all the above will remain in effect.

    Ventilation and air movement
    Detectors may not be placed directly at the outlet of ventilation, air conditioning and the like. are installed. If the air is introduced through a perforated ceiling, the ceiling must be unperforated for 0.6 m in all directions around the detector.
    Do not place detector:
    - There, where the air flows poorly (niches, corners, ceiling ridges on A-roofs, etc.)
    - where it is dusty, smoking or steam occurs
    - in places where the air flows intensively (close to fans, heat sources, ventilation mouths, drafts, etc.)
    - in kitchens and damp rooms (steam, smoke and oily vapor can cause false alarms or detection failure)
    - next to fluorescent or energy-saving lamps (electrical fault can cause a false alarm)
    - in places with large numbers of small insects

    Attention: Most often the detector is activated undesirably due to an incorrect installation location.
    More detailed installation instructions can be found in TS 54-14 and 34 2710.

    Follow the advice given in the previous paragraphs during installation.

    Figure 6: 1 – detach detector (pick up); 2 – fix detector (set up); 3 – optical signaling of status; 4 – orientation arrow for setting up; 5 – serial number; 6 – configuration jumpers; 7 – place for inserting the batteries

    1. Open the detector's screen by turning it to the left (1).
    2. Screw the plastic back panel into place at the selected location.
    3. Set the configuration jumpers (6) according to the table below
    4. Follow the installation manual of the control panel. Basic Steps:
    a. Select the desired position in the F-Link program on the Peripherals card and start the learning mode with the Add button.
    b. Inserting the last battery in the detector sends the learning code to the system – the signal light (3) flashes briefly as confirmation of sending.
    5. Place the detector on the plastic back wall. It can only be done in one position, indicated with arrows (4) on both plastic parts. Turning the detector to the right (2) fixes it.

    The detector can also learn into the system by entering the serial number (5) through the F-Link program or through the keypad (or barcode reader). All digits below the barcode must be entered (1400-00-0000-0001).

    Set detector
    The properties of the detector can be set in the F-Link program on the card Peripherals and by means of the connections in the detector.

    1 ON Immediate alarm 3 OFF smoke (EN 54-7) or heat (EN 54-5)
    OFF Fire alarm 4 OFF
    2 ON memory is on 3 ON smoke only (EN 54-7) (no heat)
    OFF memory is off 4 OFF

    3 OFF heat only (EN 54-5) (do not smoke)
    4 ON
    3 ON Simultaneous smoke and heat (both conditions simultaneously)
    4 ON

    Jumper 1 INS selects whether the detector will send the fire alarm or immediate alarm (used when normal conditions include smoke - fireplace, cigarettes, etc.) to the control panel when activated. It applies if the response set to Fire or Immediate is set at the control panel. If a reaction other than Basic has been set by the F Link program, the control panel will react depending on the setting via Reaction in the Card Peripherals.

    Jumper 2 MEM Alarm memory signaling – if enabled, optical signaling on the detector remains active for 30 minutes after alarm status has ended.
    Jumper 3 and 4 SMOKE and TEMP Combination of these jumpers determines whether the detector will respond to smoke, heat, ….

    Fire alarm
    Optical detector: After smoke enters the detector, the alarm is activated, the red signal light will flash quickly (approximately 8x per second). The indication remains on until the room is ventilated (and thus the detector's detection chamber).

    Temperature sensor: As soon as the temperature exceeds the limit set in the detector, an alarm is activated, the red signal light starts flashing quickly (approximately 8x per second). The indication remains on until the temperature drops, e.g. due to ventilation of the room.
    Alarm Memory: When the alarm memory indication is enabled, the signal light will continue to flash the activation of the detector for 30 minutes after the end of alarm status. The indication can be stopped by activation of the tamper sensor by momentarily lifting (turning) the detector.

    Tamper alarm: When the detector is picked up, it sends a tamper signal.

    Detector testing and maintenance
    Operation of the detector can be checked with a test spray. The test should be performed once every 30 days. The detector must be regularly cleaned of dust, cobwebs and the like. be stripped, no other maintenance is required.

    Note: Never test the detector by creating an open fire in the object.

    Replace batteries in the detector
    The system automatically reports when the batteries are running low. A weak battery is also indicated by a flash every 30 sec. Before replacing the batteries in the detector, the system must be switched to Service mode (otherwise tamper alarm will be triggered). It is necessary to always replace all three batteries at the same time and use the same type from the same manufacturer. After the batteries are inserted, an auto-test starts automatically, checking the voltage of the batteries, the condition of the detector and this information is sent to the control panel.

    Indication of malfunction
    The detector checks its own operation. As soon as a malfunction is detected, the indicator light continues to flash rapidly for 1 minute and then three short flashes every 30 seconds. In this case, remove the batteries for 1 minute and then reinsert them. If the light starts flashing again after about 1 minute, take the detector to service.
