DEVICE POSITIONING FOR RADIO COMMUNICATION PERFORMANCE AND STABILITY

• The conventional expander module must have a good radio communication with its wireless system’s child devices. In order to achieve this,
• before positioning it and installing it, apply scrupulously the following points:
• Avoid installing the module close to: · equipment using large amounts of electrical current
• large metal objects, structures or metal ceiling structures
• fluorescent lighting fixings
• computers, their cabling and network cabling.
• If there are other wireless translators or wireless modules, keep a distance between them of at least 2 meters. In general every installed radio device (child devices included) must have a minimum distance of at least 2 meters from each other.
• It is recommended to install the conventional expander at a height from the floor of at least 2 – 2.5 meters.
• Install the conventional expander perfectly flat on the wall.
• The conventional expander must be installed perfectly straight on the wall; this means that the antenna under the device must be perpendicular to the floor and the antenna on the right of the device must be parallel to the floor.
• Environmental parameters (temperature, humidity and so on) must be in the ranges specified in the conventional expander’s technical specifications, which can be found at the beginning of this manual; this point applies, obviously, to all other wireless devices.
• After having installed the conventional expander, make sure that its child devices (sensors, call points, etc.) are reached by a good, strong signal (refer to the single device’s manuals) in their position of installation.
• Radio transmission ranges for the conventional expander can found in the technical specifications at the beginning of this manual.
• Use the personal computer’s “Wirelex-fire” software for configuring and administering the system.

PLACEMENT AND FIXING

• The conventional system expander module’s lodgement box is designed with four 20 mm breakable, “knock-out” entry holes (two at the top and two on the upper side of the rear of the box), allowing sealed, cable gland fitted, cables to be connected to the device.
• To place and fix the module perform in sequence the following steps:
• Find a suitable location for the device’s box.
• Prepare the cable openings on the box.
• Securely and adequately fix the device’s box to the wall with adequate screws.
• Fit the cable’s gland (or glands) into the “knocked out” device box’s cable entry; check the gland’s IP rating: it must be equal or greater than the IP rating of the expander module: see the TECHNICAL SPECIFICATIONS table.
• Feed the cables into the box, giving them sufficient length for a secure connection

WIRING CONNECTIONS

• The conventional system expander module’s wiring phase of the installation has the following objectives:
• Connect the power supply cables (either from the control panel of from an independent source).
• Connect main and backup power supply monitoring inputs (optional).
• Connect the conventional zone line.
• Connect the control panel’s sounder output (optional).
• Install the end of line (EOL) resistors required as specified in this manual; their values must be chosen according to the control panel’s specification and literature.

WIRING WARNINGS

• Three warnings about wiring:
• Perform any wiring operation with the power supply source and the control panel inactive.
• Electrostatic sensitive device: observe precautions when handling and making connections.
• Connections to the terminals are polarity sensitive, thus, please, check them by referring to the wiring instructions of this manual.

IMPORTANT NOTE

• Check and apply the “ZONE ALARM EOL” and the “CHECKING THE POSITIONING OF THE ELECTRICAL BRIDGES“ paragraphs before using the expander module.

DEVICE WIRING – POWER SUPPLY

• The conventional system expander module must be power supplied either:
• directly by the control panel or
• from an external power source or
• from an external power source with a power backup unit.
• Use the scheme at the right for connecting the power supply to the device.
• This terminal wiring scheme is always applied.
• If you want to use an external power source with a power backup unit, two additional module terminal blocks come in use: “MAIN MONITORING” and “BACKUP MONITORING”.
• MAIN MONITORING” is a terminal that supervises the main power supply of an external power supply unit.
• BACKUP MONITORING” is a terminal that supervises the backup power supply of an external power supply unit.
• Let’s have two examples of power supply units:
• MAIN MONITORING” and “BACKUP MONITORING” lines will be connected to the module as in the following scheme:

DEVICE WIRING – CONVENTIONAL ZONE LINE

• In order to connect this device to the conventional zone line, two types of schemes can be used, depending on the positioning of the expander module on the line:
• the expander module is positioned at the beginning or in the middle of the zone line (conventional devices follow the device on the line or are positioned before and after it); therefore the zone line EOL resistor must be fitted externally as is normally done, but not into the device’s terminal blocks:
• the expander module is positioned at the end of the zone line (all conventional devices are positioned before it); therefore the zone line EOL resistor must be fitted to the device’s terminals and not externally as normally is done.

DEVICE WIRING – CONTROL PANEL SOUNDER OUTPUT LINE

• Conventional sounders are installed on the sounders line and the voltage level applied to their terminals by the control panel controls their functioning by activating or deactivating them (silencing).
• Wireless sounders are controlled in the same exact way through the wireless expander module; this means that this kind of radio outputs respond indirectly to the voltage level applied by the control panel to the sounders line positive and negative terminals of the expander module.
• In order to connect the module to the sounders line, two types of schemes can be used, depending on the positioning of the expander module on this line:
• the expander module is positioned at the beginning or in the middle of the sounders line (sounder devices follow the module on the line or are positioned before and after it); therefore the sounders line EOL resistor must be fitted externally as is normally done, but not into the device’s terminal blocks:
• the expander module is positioned at the end of the sounders line (all sounders are positioned before it); therefore the sounders line EOL resistor must be fitted to the device’s terminals and not externally as normally is done.

CHECKING THE POSITIONING OF THE ELECTICAL BRIDGES

• In order to function, the wireless expander module needs to have two electrical bridges fitted on the pins on its PCB in the way illustrated in the following picture:

VISUAL LED INDICATOR

• The conventional expander module is equipped with a three-colour LED (red, green and amber) that provides visual indication for power supply conditions; this indicator is positioned on the internal PCB of the device and it’s light is visible through a slit on the device’s cover.
• The table 1 illustrates the possible LED visual signals and their meaning.

PROGRAMMING THE WIRELESS SUB-SYSTEM

• The wireless sub-system is created and programmed through the use of a “Wirelex Fire” program installed on a personal computer that is connected via RS232 serial port to the wireless conventional system expander module.
