Modular multi-sensor fire detector, adapter and method for simplified installation on a wall

A modular multi-sensor fire detector, comprising:

• an evaluation unit having a housing,
• a plurality of sensor heads, and
• at least one adapter,
• wherein each of the plurality of sensor heads has a sensor housing, and each sensor housings of the plurality of sensor heads is spaced apart from one another and from the housing of the evaluation unit and is connected to the evaluation unit in a signal-conducting manner,
• wherein the evaluation unit is connected in a signal-conducting manner to a spaced-apart alarm-signal receiver, such that the evaluation unit, the sensor heads and the alarm-signal receiver are not integrated in a common housing or in a plurality of housings attached to one another,
• wherein at least one of the plurality of sensor heads comprises at least one hazard parameter conductor, and
• wherein the at least one hazard parameter conductor comprises a mounting tube having a proximal end, a distal end and a fastener at the proximal end,
• wherein the at least one adapter is attached to the mounting tube, and
• wherein the at least one adapter comprises a first fastening point, a second fastening point and a third fastening point,
• the first fastening point configured for connection to the fastener on the mounting tube,
• the second fastening point configured for connection to a capping device, and
• the third fastening point configured for connection to a wall.
