Installation Guide

Product description and intended use
This is smoke alarm with an optical sensor for installation in residential buildings, apartments and rooms with residential-like use. Smoke alarms are designed to provide an early warning of fire smoke and fires to persons present, so that these persons can react appropriately to the hazardous event. Always consult local regulations for smoke alarms.

Where to install a smoke alarm
Smoke alarms must be installed in such a way that they can be reached unhindered by the fire smoke so that fires can be reliably detected during the development phase.

• Install at least in sleeping areas (especially children’s rooms).
• Install at least in escape rooms.
• In the middle of the ceiling of a room.
• At least 50cm away from the wall and other objects.
• Maximum installation height of 6 meters.
• If ceiling installation is not possible, the smoke alarm can be installed on the wall. The distance to the ceiling should be between 30 and 50 centimeters.

Where to install a smoke alarm in rooms with special geometries

• Corridors with a maximum width of 3m: Max. 15m between 2 smoke alarms. Max. 7.5m to the front side of the gallery and smoke alarms at edges/crossings of corridors.

• Rooms with sloping ceilings:
  – Ceiling inclination is > 20° to the horizontal: Smoke alarms must be installed at least 0.5m and at most Im from the ceiling top.
  – Partial roof slopes: If the flat ceiling is < Im wide, consider as ceiling inclination is of > 20°. If the flat ceiling is >Im wide, consider as flat ceiling.

• Rooms with subdivided ceilings:
  – Height of the subdivisions is < 0.2m: Beams without consideration: smoke alarm may be installed on the beams or the ceiling.
  – Height of subdivisions is > 0.2m and area of ceiling panels > 36m?: Smoke alarm should be installed in each ceiling panel.
  – Height of subdivisions > 0.2m and area of ceiling panels < 36m: Individual ceiling without consideration.

Where not to install a smoke alarm

• In an environment with a high risk of draught (e.g. close to air conditioning, fans and ventilation outlets). The movement of air can impair the penetration of fire smoke into the smoke alarm.
