The following steps should be taken for the blow-through
process of the pipe system:
1. Connect the compressed air supply (compressor or mobile blow-through
device), which is necessary for the blow-through of the pipe system, to the
3-way socket ball valve via the quick-acting coupling sleeve of the blown-
through pipe system.
2. Separate the pipe system to be blown-through via the 3-way socket ball
valve from the relevant device by re-setting the ball valve from 0º- operating
position to 180º(see fig. 6.11).
3. Manually blow the pipe system through for 10 seconds.
4. Set the ball valve to 90º. In this position the device is neither connected to
the pipe system nor the pressed or compressed air supply. Wait about 20
seconds so that dust and dirt disturbed in the pipe system can settle and not
be aspirated by the smoke detection system.
5. Re-connect the blown-through pipe system with the device within the next 10
seconds by again positioning the ball valve to 0º.
One single blow-through process must be completed in 50 seconds. If a
blow-through process is carried out within this time and the device re-
connected with the pipe system, the fault alarm “air-flow sensor module
fault” is not activated. If another blow-through process is necessary, the
above mentioned process must be repeated
at the earliest after 120
seconds
.
