The control unit module receives information transmitted by detectors and in response, send signals that
are necessary to control other devices or systems for instance valves, alarm systems (warning LED displays,
sound and light warning beacons) or yet other automation systems deployed within the building.

Equipment layout
4.1.1
Deployment of gas detectors
For installation of the Gas Detection & Safety System in a garage or a car parking facilities the assumption
can be made that one detector is necessary for each 120 to 200 m
2
. However, the detailed layout depends
also on local conditions, i.e. availability and efficiency of a ventilation system, presence of locations for
potential accumulation of gas.
Detailed information with regard to layout of detectors can be found in User Manuals for specific
equipment.
4.1.2
Location for a control unit module
Components of the control unit shall be mounted inside a control cabinet on a DIN 35 rail or in a terminal
cabinet (Atest Gaz offers a kit of the control unit components enclosed into a dedicated housing).
4.1.3
Locations for a shutoff valve and the Control V controller for the valve
The location for the shutoff valve controller is strictly associated with the place where a shutoff valve is to
be mounted pursuant to requirements of the gas supplying system.
Please pay attention to the distance between a valve and a controller. Such a distance depends on the valve
type and the diameter of an interconnecting pipe. For more details please refer to the User Manual for the
Control V device.
4.1.4
Location for warning LED displays
Designers of a Gas Detection System must take account for the following recommendations with regard to
locations of warning LED displays:
warning LED display shall be placed at the sufficient height to enable undisturbed and safe traffic
of persons and vehicles,
depending on a message to be displayed the warning LED display shall be mounted at the
following locations:
• above or next to ingress/egress doors of a garage,
• in communication roads,
• above or next to an ingress/egress gate of a garage,
installation height shall be properly selected so that to enable easy access to a warning LED
display.
4.1.5
Location for sound and light warning beacons
Sound and light warning beacons shall be mounted at such locations that guarantee good visibility of
messages.
