Verify that the audible alarm signal of the product can always be heard,
even in the case of ambient noise.
If audibility cannot be ensured, you must install an additional alarm unit at a
suitable location in the building (for example, additional alarm unit ZAG 01,
horn KH 1 or combined alarm light and horn from AFRISO).
Generate a vacuum of approx. -400 mbar in the interstitial space. Use an
installation pump with a greater capacity for this purpose.
Check for leaks in the interstitial space. A slight pressure drop in the first
hour is possible. After that, the pressure must not drop any more.
