Tips On Installing Home Smoke Alarms
  • • In areas where ventilation and/or air conditioning systems are used is must be ensured that air movement does not affect the function of the smoke detector.

    • Smoke detectors must be permanently fixed on the ceiling. Mounting instructions must be observed.

    • Choose a mounting method that ensures a holding force of at least 20N in vertical direction.

    • The smoke detector is designed for monitoring residential buildings or residential premises (not for industrial or commercial usage).

    • A function test must be performed on each smoke detector after installation.

    • The functionality of each installed smoke detector must be regularly checked and maintenance measures must be ensured. Perform function test 1 per week, clean every 3months.

    • Smoke detectors must be taken out of service at the latest after 10 years and replaced with a new device.

  • For apartments and single familyhomes1

    Arrangement in special room geometries
    Following distance ratios and arrangements are recommended for detector positioning:
    a)Linear corridor

  • •If a room is divided in height by a podium or a gallery, as smoke detector is required beneath these
    •installations if the area exceeds 16m2 and the length and width exceeds each 2m.
    •In rooms with ceiling slopes > 20°to the horizontal, a heat pocket can form at the top of the ceiling which prevents smoke entry into the smoke detector.
    •Therefore, smoke detectors in these rooms must be mounted at least 0,5m but no more than 1m from the ceiling top, see the following 2illustrations.
    •In rooms with a slope ≤20°smoke detectors must be mounted centrally on the ceiling.
     
    Example of mounting with pedestal-shaped ceiling with a ceiling slope > 20°
    Example
    Remarks: smoke detectors can be attached on the position left (1) or on the position right (2).
  • For ceiling with joists (height (h) of the joist ≤0.20m and an area of the ceiling box >36m2 or ≤36m2).

    a)Example for ceiling>36m2
    Notes for ceiling installation
    b)Example for ceiling box≤36m2
    Notes for ceiling installation1
    c)Example of ceiling with joist (height (h) of the joist>0.2m)
    Notes for ceiling installation2
    In corridors with a maximum width of 3m, the distance between two smoke detectors may not exceed 15m. The detector distance to the front face of the corridor must not exceed 7.5m. A detector must be arranged in crossings, junctions and corners (mitre line) of corridors. An example of an arrangement is shown in chapter “Arrangement in special room geometries”.
     
  • Loosen the mounting plate on the rear side of the device by turning it clockwise.
    Fix the mounting plate with the help of the enclosed mounting material to the ceiling or wall. Check first whether the supplied mounting materials is suitable for the structural quality of the wall/ceiling.
    Insert the smoke detector in the mounting bracket and rotate the smoke detector anti-clockwise direction until it audibly engages.

    Mounting locations

    Mounting locations for smoke detectors:

    • Bedrooms, childrens rooms and corridors must be equipped (basic requirement) with smoke detectors.

    • Always on the ceiling.

    • 50 cm from the wall (or beam).

    • If the room is subdivided by ceiling-high furniture etc., a smoke detector must be installed in each room partition.

    • In rooms with a floor area 60m2, divided into ceiling boxes by beams or joists, the following applies:

    - In ceiling boxes bigger > 36m2 a smoke detector must be installed per ceiling box (see Fig- ure1a).

    - In ceiling boxes 36m2 and with ceiling slopes 20°as well as beams or joists with a height 0.2m, the individual ceiling boxes are not taken into account (see Fig 1.b). Install smoke detectors as centrally as possible in the room, in a ceiling box or on the joist.

    - In these rooms have beams or ceiling joists with a height >0,2m, the smoke detector must be installed on a beam or girder, as centrally as possible in the room (see Fig c).

    • In rooms with a floor area of >60m2, an additional smoke detector must be installed per60m2.

  • Press the test/hush button, if the red indicator light flashes quickly and continue alarms at the same time, it means the detector is working properly. At the same time, the detector enters low sensitivity detecting state, the red LED light flashes every 10 seconds approx. About 9 minutes later, it enters normal detecting state from low sensitivity detecting state automatically. Or press the test/mute button again and cancel low sensitivity detecting state.
    Erratic or low sound coming from your alarm may indicate a defective alarm, you can refer to “Trouble shooting”section for solution.
     
    LED indicators
    •Red LED-flashing once every 344 seconds: indicates that the smoke alarm device is operating properly.
    •Red LED-flashing: when the test button is pressed, or when the smoke alarm device sense particles of combustion and goes into alarm (constant pulsating sound), the red LED will flash once per second. The flashing LED and pulsating alarm will continue until the air is cleared or release test button.
    •Red LED alarm silencer (Hush mode) indication: The red LED will flash once every 10 seconds, indicating the smoke alarm device is in the alarm silence (hush)mode.
    •Low battery indication: An intermittent “chirp”with red LED flashes once every 43 seconds: indicates that the smoke alarm device is low battery, you may press the test button longer time for pause alarm for 8 hours, but it will reset automatically after 8 hours.
    •Fault indication: the alarm occurs every 43seconds.
    •Alarm memory: After alarm is made, the detector will have alarm memory. The green LED will flash quickly for 3 times every for 43 seconds. So the user can tell if the detector has entered alarm state from a distance without touching the detector. LED display will quit after 24 hours. The first time you press the test/mute button after alarm is made, the detector will hint by special alarm mode. After releasing the test/mute key, alarm memory will be reset. Then you press the test/mute button and it will be normal key test.

    Alarm silence (hush mode)
    During the unit is alarming, you push the test button, it will be paused the unit alarming for approx. 9 minutes. The red LED will flash once every 10 seconds, it indicates the smoke alarm device is running into the silence mode.
    Smoke alarms devices are conceived to minimize nuisance alarms.
    The smoke alarm will automatically reset after approximately 9 minutes, if after this period, particles of combustion are still present, the alarm will sound again.
    The alarm silencer (silence mode) can be repeatedly used until the air has been cleared of the conditioning causing the alarm.
    Caution: Before using the alarm silence (hush), identify the source of the smoke and be certain a safe condition exists.
    Danger: If the alarm sounds, and it is not being tested, it means the unit is detecting smoke, THE SOUND OF THE ALARM REQUIRES YOUR IMMEDIATE ATTENTION AND ACTION.

    Fraud alarm/ false alarms
    False alarms can be triggered by the following, for example:
    Welding and cutting work, Soldering and other hot work, Sawing and sanding work,
    Dust due to construction or cleaning, Water vapour, cooking vapours or odours, Extreme electromagnetic influences,
    Temperature fluctuations, which lead to the condensation of the humidity in the smoke detector.

    In the event of works in the environment of the installed smoke detector which trigger false alarms (e.g. renovation), the detector should be temporarily covered or removed. After completion of the work, the original functionality of the installed smoke detector must be restored as described in previous sections.
    Should the system report an alarm, please check whether the fire really exists. If so, call the fire brigade.
    If not, please check whether the mentioned reasons could have raised the alarm. We would like to point out that we are not liable for the consequences of false alarms. We do not cover any costs incurred by false alarms, such as for deployment of police, fire or key services.
The Maintenance Of Home Smoke Alarm Is Important

Maintenance

 

This includes at least a check of whether the smoke penetration openings are free (e.g. covers, pollution caused by fluff and dust), whether there is function-related damage to the smoke detector and whether the area of 0.5m around the smoke detector is free of obstacles (such as furniture), which inhibit the penetra- tion of fire smoke into the smoke detector. If contamination is detected in the smoke penetration openings, there should be cleaned according to manufacturer instructions. If there is function-related damage to the smoke detector, it must be replaced. If the installed smoke detector does not have the required clearance around it, the mounting location must be inspected and a new location determined if necessary.
