Featured Home Smoke Alarms

Example for use in a single-family home

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

a)Linear corridor

b)Rectangular corridor

c)Detector arrangement in large corridors

d)Detector arrangement in large corridors withcorners

 

Example of mounting with pedestal-shaped ceiling with a ceiling slope > 20°

Remarks: smoke detectors can be attached on the position left (1) or on the position right (2).

b)Example for ceiling box≤36m2

c)Example of ceiling with joist (height (h) of the joist>0.2m)

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”.

Mounting locations

Mounting locations for smoke detectors:

• Bedrooms, children’s 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.

 

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.
