Mounting Location and Installation
The power and flexibility of the
H
uman Detector
Flex
alarm system lies in its wireless radio connection. Due to the
transmission frequency and protocol, a high level of security is ensured. The modulation process contributes to an
increased range compared to products from various competitors. To ensure unrestricted wireless radio operation, a
few basic rules should be observed:
·Do not install the alarm control panels and the alarm management systems directly on metal
surfaces.
·If this is not possible, a minimum distance of approx. 40 cm should be kept from the metal surface.
This is important to ensure proper radiation of the high frequency.
·Choose the installation position of the alarm control panels and the alarm management system to
avoid the presence of large metal parts between these and the sensor modules, if possible. The
further away the sensor modules are, the more critical large metal parts become to the path of
transmission.
·Choose the installation location to provide access to the alarm control panels and alarm
management systems.
·Under no circumstances may unauthorised persons have free access to the alarm control
centres and alarm management systems. This also applies to any connected cables.
Choosing the location for installation
When choosing the location for the installation of the
HDF-SPEECH
alarm control panel, you need to ensure that the
alarm can detected. There are several requirements for this.
·The alarm control panel should be installed in such a way, that the sound of the alarm
or voice message can be heard at the desired location.
·The alarm control panel should also be installed in such a way that the sound of the
alarm sound disturbs people in more distant locations as little as possible.
·If several alarm sensors access an HDF-SPEECH alarm control panel, it must be
installed at a central location. It should be detected in all positions of the alarm sensors.
After a suitable position has been found, provide an operational power supply line. Ensure,therefore, that the cables
are installed in such a way that they cannot be tempered with, dismantled or get damaged by others.
The ideal position normally is:
·
Elevated and not accessible without a ladder.
·
Elevated and exposed, so that it can be easily reached by all alarm sensors via radio.
·Hidden in furniture or behind panels so that it can not be tampered with or get
damaged.
Note:
The HDF-SPEECH alarm control panel offers output of voice and sound messages to external loudspeakers as an
option. A maximum audio power of 10 watts is available for this purpose. Due to the impedance of the audio amplifier
in the alarm centre, the connected passive speaker should not be further away than approx. 15m. Suitable line drivers
and additional audio amplifiers can be connected.
Aligning the antenna with the alarm centre
For maximum reception range the 1/4 lambda antenna should be vertically aligned. This means that the antenna
points vertically up or down. Deviating from this is possible, but results in a reduction of reception quality.
