How to use:
- Please confirm the induced gas is heavier or lighter than air. Heavier gas than air such as LPG etc. Lighter gas than air such as natural gas, marsh gas etc
- Choosing the proper position to install the Detector according to the gas specific gravity. Detecting gas is heavier than air: Installation height from floor: 0.3-1.0m, Semi-diameter to gas source: <1.5m;Detecting gas is lighter than air: Installation height from ceiling: 0.3-1.0m, Semi-diameter to gas source: <1.5m
- Fix the screw into the wall firmly, then hang the detector
- Avoid installing the detector too close to the following sources of interference: direct air flow from vents, fans, doors, windows, sources of steam, oil vapor, etc
- All wires installation must accord with the National and Local effective laws and criteria. The wires must have suitable size and colorful marks to avoid connecting error. And unseemly connection of wires will result in the alarm error while gas leaking happened
- A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and/or visual alarm from the detector itself
- Smoke detectors are typically housed in a disk-shaped plastic enclosure about 150 millimetres (6 in) in diameter and 25 millimetres (1 in) thick, but the shape can vary by manufacturer or product line. Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. Sensitive alarms can be used to detect, and thus deter, smoking in areas where it is banned such as toilets and schools. Smoke detectors in large commercial, industrial, and residential buildings are usually powered by a central fire alarm system, which is powered by the building power with a battery backup. However, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery
Carbon monoxide and carbon dioxide detection:
- Some smoke alarms use a carbon dioxide sensor or carbon monoxide sensor in order to detect extremely dangerous products of combustion. However, not all smoke detectors that are advertised with such gas sensors are actually able to warn of poisonous levels of those gases in the absence of a fire
- Performance differences
- Optical or "toast-proof" smoke detectors are generally quicker in detecting particulate (smoke) generated by smoldering (cool, smokey) fires. Ionization smoke detectors are generally quicker in detecting particulate (smoke) generated by flaming (hot) fires
- According to fire tests conformant to EN 54, normally the CO2 cloud from smoke can be detected before particulate
- Obscuration is a unit of measurement that has become the standard definition of smoke detector sensitivity. Obscuration is the effect that smoke has on reducing visibility. Higher concentrations of smoke result in higher obscuration levels, lowering visibility
