The intermediate inspection of the intrusion detection installation is used to address any defects in its initial phase and to prevent them from happening again.
It is also during these intermediate acceptance tests that specific measures must be taken (e.g. on wireless systems), so that approval is not blocked at the end of the project.
These intermediate inspections will also prevent any reservations in the acceptance reports as well as any critical comments during acceptance. They enable the installation to go through a smoother acceptance procedure, as it no longer has major problems likely to put installers in financial and contractual difficulties.
Its acceptance simply becomes a formality, will take less time and will no longer be a major concern for the project manager and other installers.
It is therefore advisable to conduct these intermediate inspections before the installation approval procedure.
