4. Commissioning the system
4.1 Responsibility for commissioning the system
Commissioning and voltage setting should only be carried out by
authorised technical personnel.
4.2 Pre-commissioning check-list
The following check-list should be implemented prior to
commissioning the system:
1. Check that all equipment, electrical wiring and pipe loops are as
per specification and that the installation is in accordance with the
drawings.
2. Check that all the cables have being connected to the correct
terminals and with correct polarity.
3. Check that the cables are free from external voltage.
4. If the AutroSense 75 detector unit is connected to a analogue
addressable fire alarm system:
-
check that the interface board and detector is coded to the
correct address
5. Check that the sampling holes are drilled at specified locations in
the exhaust pipes. De-burr each sampling hole to ensure that the
pipe is free from any obstruction that may affect the airflow.
6. Check that all markings, instructions and layout diagrams are in
accordance with the specifications.
7. Check that the pipes are properly fixed, that all joints are sealed,
and that the system is cleaned out.
8. Check that the ends of the pipes are open, that there are no strong
air currents around the pipes, and that ends of concealed pipes (e.g.
pipes installed above the ceiling) are led down into the room and
have the same pressure as the detector.
9. Check that the return pipe ends in either the same room as the
detector, or the same room in which the pipe system is installed,
or in a low pressure zone relative to the exhaust pipe.
