IMPORTANT: please note that with this wiring
configuration, if a fault occurs on the wireless
sub-system, all the remainder sounder output
line, subsequent the expander, is isolated from
the system until the fault itself is handled and
reset; this occurs unless each sounder on the
sounder output line is equipped with a Schottky
diode and the control panel provides for their
use.
Please refer to your applicable codes of prac-
tice and to your conventional control panel
documentation.
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.
ZONE ALARM EOL
The zone alarm end of line (EOL) resistor must ALWAYS be installed on the expander; to have its value refer to your control panel’s litera-
ture.
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.
In order to gain additional information on the “Wirelex-Fire”, please, consult the latest revision of the “Guide to wireless system
installation” (code: APN-W0001) obtainable from your supplier or directly from the manufacturer.
TESTING THE WIRELESS CONVENTIONAL SYSTEM EXPANDER MODULE
Testing needs the fire security system to be wired, programmed and armed.
Trigger an alarm on the wireless sub-system: as a consequence the conventional control panel must set into alarm.
After the test reset the whole system from the control panel.
SEALING THE DEVICE WITH ITS COVER
After testing you can install the device’s cover onto the module and, safely and securely, close it by using the screws provided.
