System architectures

6.1

Data bus architecture

In this system gas detectors are connected to the bus via T-connectors S2.

Life cycle

7.1

Transportation

The device can be shipped in the same way as new equipment of that type. If the original package or
another protecting means (e.g. corks) is unavailable the conveyed equipment must be secured against

shocks, vibrations or moisture by means of adequate methods and material at the own responsibility of the
sender. 
The device can be conveyed under environmental conditions as described in Table 5.

Installation

7.2.1

Deployment of gas detectors

Deployment  of  gas  detectors  must  be  determined  by  the  system designed  with  consideration to  the

following rules:

installation of detectors is recommended somewhere 30 cm below the topmost point of the
ceiling – methane is lighter than air and tends to migrate upwards, 
detectors should me mounted at locations where gathering (accumulation) of gas is expected due

to architectural properties of the facility (e.g. in the facility part that is separated from the entire
space by means of walls or other structural components),
