3 Product Description
Function Description
In order to prevent the spread of smoke in buildings
through the ventilation and air conditioning
systems, it is important to detect the smoke at an
early stage.
The smoke detector RM-O-3-D is used to control
and trigger fire and smoke dampers. It works
according to the scattered-light principle and
detects the smoke independently of temperature,
so that fire dampers close even before the
triggering temperature has been reached.
In addition, can be caused by the
Rauchauslöseein-direction switching off the fan.
The closing of the fire or smoke protection
damper occurs in the case of smoke detection by
interrupting the supply voltage.
The smoke detector can be used for fire or smoke
dampers with the following triggering devices:
• Electric spring return actuator (normally
CLOSED)
• Pneumatic drive (pressureless CLOSED)
• Holding magnet
