It is our most sale smoke detector which used to detect smoldering smoke and warn us to take proper measurement before a fire, it can increase the chance of escape and reduce the casualty rate and reduce losses from a fire.
It is photoelectric independent smoke alarm with 3V lithium battery which composed of sophisticated analog circuit and digital circuit. It is with high sensitivity and in low power consumption. Meanwhile, it has local smoke alarm memory and hush function which can stop the false alarm immediately. This product is our classic model in a small volume design and built-in large-capacity battery can provide service life of 10 years.
• 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.
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.
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.
