General DG168 Battery Powered Photoelectric Smoke Alarm with excellent stability and high-sensitivity . Key Specifications/Special Features Power Source: 9V Battery (included). Audio Alarm: ≥ 85dB/3m Temperature Range: 0 to 40 Humidity Range: 5%-95% relative humidity(RH) Sensor: Photoelectric Size: diameter 106mm in diameter x32mm depth Interconnects: No Easy to install with mounting base included Suitable for any room Low battery signal Test button for simple testing Smoke alarms sound their alarm horn when they detect smoke. Everything preventing the smoke from reaching the alarm obstructs an early alarm. A single smoke detector provides only limited security. Fire in another room will only be detected after smoke reaches the alarm. It is therefore recommended to install a smoke alarm on every level of the home if not in every room. Inform yourself about fire safety rules and proper behaviour in case of a fire at your fire brigade Product characteristics Photoelectric effect This recently developed photoelectric sensorcamber 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 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 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 smoke alarm 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 l As most fires in flats start in the living areas, it is recommended to install smoke alarms between the living and sleeping areas. l 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. l The minimum requirement for multistorey 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. l A smoke alarm shall be installed in the sleeping area of a caravan. l For complicated or extensive properties please request qualified advice from a safety engineer or the fire brigade. Regarding the installation of single smoke alarms it is distinguished between minimum and additional protection:
