Ceiling Lead-Through Adapter - Bosch FCS-320-TM Operation Manual

FCS-320-TM Aspirating Smoke Detector
As the clips are more stable under pressure and the elastic rubber insert significantly
improves the cleaning effect, they are used for all plans and designs which require a blow-off
system due to environmental influences (e.g. increased exposure to dust).
NOTICE!
The standard AF-x aspiration reducing film sheets and the marking tapes are not suitable for
use in low-temperature areas.
The aspiration reductions with plastic clips are available separately.

Ceiling Lead-through Adapter

Figure 2.19 Ceiling lead-through adapters
A concealed pipe system for area monitoring can be realized by installing in a false ceiling.
This requires the use of ceiling lead-throughs in the false ceiling. The ceiling lead-through can
be used with a false ceiling thickness of up to approx. 35 mm. In line with the planning and
design guidelines, the ceiling lead-throughs are fitted with aspiration reducing film sheets
with defined air sampling openings and connected to the pipe system by means of aspiration
hoses (see Figure 2.19).
If these hoses do not exceed a maximum of 3 m, the plan according to Section 3 Planning,
page 31 applies. If structural circumstances dictate that lengths in excess of 3 m are used, the
pipe system has to be calculated accordingly.
