2.1.1 Site diagnosis before installation
Before installing the system and deciding on the best place for each product, a
diagnosis of the site to check its radio
transmission range must first be performed
. It is especially important to carefully check a number of specific points
including those relating to the type of professional premises:
• distances or surfaces to be monitored:
generally bigger on professional premises than residential sites,
• materials used:
metallic materials are often used in walls and partitions,
• modifications to the internal configuration of the home or premises:
these can be frequent (addition of walls or
furniture, storage of materials, etc.).
The range has been especially studied for all of these cases.
Nevertheless, system reliability does depend on the place where products are installed.
This is why we recommend performing a detailed survey of the site, with a focus on the following points:
• All metallic materials represent an obstacle to the propagation of radio transmissions
and are likely to have a
considerable impact on the link between two products.
Thus, the following cases must be avoided:
- installation of products in the immediate vicinity of apparent or hidden metallic materials (reinforced concrete walls for
example), etc.,
- metal walls, shelves, frames or trellises between a product and the control panel or a radio repeater relay.
- installation of the control panel or a relay in a plant room or in the immediate vicinity of other electrical or computer
products.
If the above environments cannot be avoided, it
is highly advisable to install a radio repeater relay
to get around these
obstacles.
• Any modification to the internal configuration or layout of the home or premises is likely to have a considerable
impact on the link between two products:
- reorganisation of the premises (addition of walls or furniture, etc.),
- reorganisation of a workshop or storage area,
- storage areas with variable capacities (notably metallic materials),
- mobile metallic doors or partitions,
- parking of vehicles (handling trucks, vehicles in a garage).
In all cases where such variations are likely, it is highly advisable to use a radio repeater relay to reinforce the link and get
around potential obstacles between various products and the control panel.
We also advise you to draw users’ attention to this fact and to check the radio links again every time the configuration of the
premises is changed.
2.1.2 Checking radio links during installation
To ensure long-lasting reliability of the radio links, it is essential to check each one in Installation mode once all the products
have been installed (see chapter on “Checking the products and radio links” in this manual).
If the layout of the premises is likely to be changed, it is advisable to check products and links for every possible
configuration.
2.1 Precautions to be taken into account before installing the system
2. Preparation
IMPORTANT: if these instructions are not complied with, random and frequent radio link losses between the various products
may be detected.
