Manual call points FDM225 and FDM226
The glass insert is covered by a foil. This foil holds the glass splinters together
when the glass insert is pushed in, making it possible to remove the glass insert
easily.
Replace the glass insert or plastic insert as follows:
The housing cover of the manual call point is removed. See the chapter
1. Completely remove the old glass insert or plastic insert.
2. Place the glass insert or plastic insert (7) onto the guides (3) and slide the
glass insert or plastic insert (7) against the alarm actuator (2), as shown in the
diagram.
This pre-stresses the spring (5).
3. Install the housing cover on the back box.
4. Check the function of the manual call point. See the chapter 'Checking function
49]'.
The glass insert has been replaced.
