Abus RWM450 User Manual - Setting Up The “Master”:

– 41 –

Radio group: at least two,  

maximum 15 RISAs

• All networked units of the same 

  radio group will issue an alarm 

  when at least one RISA of this group 

  detects smoke or temperatures 

  typical of fire

• The first alarm to be activated is 

  temporarily assigned the “master” 

  function (of establishing and mana- 

  ging the radio group)

• This first-activated alarm should 

  be fitted in a central position  

  (e.g. landing or corridor)

Common radio group: is also a normal 

radio group

• where one or more radio groups 

  (e.g. a flat) are linked to a specific 

  radio group (e.g. stairway), this 

  becomes a common radio group.

• All interlinked alarms of a radio 

  group trigger an alarm (e.g. in a flat)

• All alarms of the common radio 

  group (e.g. stairway) will also, after 

  a delay period of roughly 60 seconds, 

  issue alarms if they are linked as 

  a common radio group to the radio 

  group of the flat

• Alarms are transferred only from the 

  radio group (e.g. flat) to the com- 

  mon radio group (e.g. stairway)

• There is no transfer in the other di- 

  rection, from the common radio 

  group (e.g. stairway) to the radio 

  group (e.g. flat)

• Up to 14 radio groups can be inter- 

  linked to a common radio group

• A radio group cannot be linked  

  to a common radio group and  

  also with other radio groups

Setting Up the “Master”:

Remove the black activation pin 

(which also acts as activation protec-

tion); but this will still be needed.

Press red activation button
