Positioning The System Devices - Urmet 1068 Série Mode D'emploi

2.3.4.4 External communications

The type of communication used externally (telephone landline, mobile, SMS, etc.) may influence the certified grade
of security. When in doubt, always select the solution or device that guarantees the highest level of certification.

Due to technical or economic reasons, it is not always possible to choose the best solution. In this case, even the
most restrictive solution is preferable to a non-solution.

When making a decision, always consider not only what the control panel can communicate externally, but also what
can be communicated externally to the control panel, or in other words, how it can interact remotely with the alarm
system. Succeeding in interacting remotely with the system though the control panel may mean reducing
maintenance costs and having a system that is always efficient.

It is not always necessary to choose. If the budget and the technical characteristics allow it, various types of
communication may coexist, each of which may act as a back-up to the others. Redundancy is a plus, because the
certainty that alarm notifications are received increases.

Positioning the system devices

Unless they are specifically designed and constructed for outdoor installation, like the outdoor sirens, all the devices
must be installed indoors, protected from the elements and vandalism.
2.3.5.1 Positioning the control panel
The control panel must be installed:

On a dry and level wall. A damp wall may lead to potential infiltrations of water that might wet the inside of the
control panel and damage it. A wavy or cracked surface may prevent a solid installation of the control panel.

In an indoor passage, suitably aerated and protected by the intrusion alarm system. It should be noted that the
control panel should not be in plain sight and that, when the system is armed, it should not be accessible to intruders
unless they are obliged to pass through areas protected by detectors.

Far from strong electromagnetic fields.

At breast height, to facilitate installation and maintenance operations.
If one should ever want to use, immediately or in the future, radio devices or connection via GSM mobile phone network,
please read paragraphs 2.3.6 Tips about installing the radio devices and 2.3.7 Tips about the mobile phone network
(GSM).
!
IMPORTANT The installation of the radio expansion results in the loss of EN50131 certification.
2.3.5.2 Positioning the keypads
Keypads must be positioned:

On a dry and level wall. A damp wall may lead to potential infiltrations of water that might wet the inside of the
keypad and damage it. A wavy or cracked surface may prevent a solid installation of the keypad.

Near the access points of the areas to be protected. In this case they are not intended only as outdoor accesses, but
also indoor ones that enable entry to a space normally protected from intrusion, like a warehouse.

In an indoor passage protected by the intrusion alarm system. When the system is armed, the keypad must not be
accessible to intruders, unless they pass through areas protected by detectors.

Installed at a height of 160 cm for standard systems, or 120 cm for systems designed for disabled individuals.

When a vocal keypad is used, position it according to the use one intends to make of it. If one wishes to use
environmental listening, position it in the area to be monitored, if compatible with the other needs; if it is to be used
for messages in loudspeaker, avoid particularly noisy areas.
