MODEL SD003

9 Volt Battery Operated

Photoelectric Smoke Alarm/Detector

 

Product characteristics

 

Photoelectric effect

This recently developed photoelectric sensor-camber is insensitive to interfering influences. Every device is separately calibrated in order to avoid false alarms due to, e.g., cigarette smoke. The power supply is electronically regulated, thereby maintaining a constant sensitivity of the alarm.

 

Battery operation

The functioning of the detector is maintained even in case of a power failure. On an average the battery’s (standard 9V battery) service life is 1 year.

 

Signal lamp (LED)

A flashing small light (every 43s) signalises a failure-free operation.

 

Fully automatic test function

Advanced electronics ensure the best possible operating readiness by means of an automatic self-test function.

 

Battery warning function

By means of a warning sound repeated every 43 seconds (for up to one month), the smoke detector signalises that the power supply of the battery is insufficient and it needs to be replaced.

 

Control button

Temporarily increases the detector’s sensitivity to test the alarm function.

 

Noisy (85 dBA) piezoelectric warning sound

Vibrant warning sound in case of fire alarm - high efficiency

 

Approved quality

Thoroughly tested to guarantee highest reliability and a long service life. Produced under rigid quality controls. Certified according to the European norm prEN ISO 12239 for single smoke detectors. CE and TÜV certified security.

 

This device does not contain any radioactive substances!

 

Function

 

Smoke caused by fire is very dangerous, especially because of today’s widespread use of synthetic materials in modern homes that might generate poisonous vapours when burning.

The SD001 smoke alarm detects smoke caused by smouldering at an early stage and warns by means of a loud, vibrant sound, thereby waking inhabitants up at a point of time when a safe escape is still possible.

The SD001 operates according to the scattered light principle. A light source and a photocell are arranged so as to ensure that normally no light strikes the photocell. The light source is activated in short intervals.

If the concentration of smoke particles in the enclosure reaches a certain level, the light is reflected and reaches the photocell. This will set off a loud fire alarm.

 

Placement

 

As most fires in flats start in the living areas, it is recommended to install smoke alarms between the living and sleeping areas.As a minimum requirement a smoke alarm should be installed outside every sleeping area in a flat. If there are separate sleeping areas a smoke alarm is to be installed outside each sleeping area.The minimum requirement for multi-storey houses is to install a smoke alarm on every floor of the house and outside each sleeping area, e.g. in the hallway connecting the sleeping rooms or on the stairway leading to this hallway. If there is a room in the attic, it is strongly recommended to install a smoke alarm on the ceiling as well.

 

A smoke alarm shall be installed in the sleeping area of a caravan.

 

For complicated or extensive properties please request qualified advice from a safety engineer or the fire brigade.

 

 

     The following locations shall be avoided:

 

Next to doors, windows, ventilators etc. where draughts can deviate smoke from the sensor.

 

In small or poorly ventilated garages or kitchens where waste gas or vapors may cause false alarms.

 

In areas where dust and dirt can interfere with the smoke alarm operation or cause false alarms.

 

In areas where insects are likely to trigger the alarm.

 

In damp or humid areas (e.g. in the bathrooms).

 

In rooms where the temperature may often fall below –5°C or exceed +38°C. Testing the alarm

 

A flashing LED signals accurate operation. A loud, vibrating sound occurs in case of a smoke alarm. A short whistling tone occurs every 30 to 40 seconds for up to one month signalling that the battery needs to be replaced.

Test the smoke alarm weekly for your security by pressing the respective button (for at least 2 seconds) until you hear the alarm.

 

If the smoke alarm cannot be heard after pressing the button or if the LED does not flash, please do check the following points:

 

1.Is the device damaged?

2.Is the device clean? (For your security please vacuum the outside cover regularly to remove dust and dirt.)

3.Is the battery working properly? Are you using the required battery type? Is the battery connected properly? Replace the battery if necessary.

 

If the smoke alarm is still not working, do not attempt to repair it but contact a professional.

 

False alarms

 

After every alarm, check if there is a fire. In case of a false alarm do not remove the battery, but fan the air around the smoke alarm until the alarm turns off (if necessary vacuum the outside cover).  After the alarm the device is immediately ready for operation.
