SAGITTARIUS CONVENTIONAL SYSTEM
EXPANDER MODULE
GENERAL DESCRIPTION
The Sagittarius conventional system expander is a module device permitting to add a wireless sub-system to a conventional fire
security installation.
This device is connected directly to the conventional control panel’s zone line and is actually part of it. This device allows wireless
sounders silencing by being controlled by the control panel’s sounder output line.
WHAT TO CHECK BEFORE INSTALLATION
Before installing the conventional system expander module
check these following items:
- This device must be installed following your national and /
or international codes of practice and standards: check them before performing the installation of this device.
- This device is compatible with most of the conventional control panels; check that the control panel is equipped with a power supply
output through which you can, if desired, power the conventional system expander module; check if the panel is provided with a
sounder output; check that control panel’s specifications are suitable; for all this, consult your control panel’s documentation or
consult your control panel’s supplier for more information.
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.
- 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 ELECTICAL BRIDGES“ paragraphs
before using the expander module.
WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to environmental deterioration.
However, after 10 years of continuous operation, it is advisable to replace the devices in order to minimize the risk of reduced perfor-
mance caused by external factors. Ensure that this device is only used with compatible control panels. Detection systems must be
checked, serviced and maintained on a regular basis to confirm correct operation.
Smoke sensors may respond differently to various kinds of smoke particles, thus application advice should be sought for special
risks. Sensors cannot respond correctly if barriers exist between them and the fire location and may be affected by special environ-
mental conditions.
Refer to and follow national codes of practice and other internationally recognized fire engineering standards.
Appropriate risk assessment should be carried out initially to determine correct design criteria and updated periodically.

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’s 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.

the device)
IMPORTANT: please note that with this wiring
configuration, if a fault occurs on the wireless
sub-system, all the reminder conventional line,
subsequent the expander, is isolated from the
system until the fault itself is handled and
reset; this occurs unless each sensor on the
conventional 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 expand-
er 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
literature.
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:
PROGRAMMING THE WIRELESS SUB-SYSTEM
The wireless sub-system is created and programmed through the use of a “Wirelex Fire” program (from release 5.0 and successive)
installed on a personal computer that is connected via RS232 serial port to the Sagittarius conventional system expander module.
Please refer to the “Wirelex Fire” instructions manual to gain more information.
TESTING THE SAGITTARIUS 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 provides screws.
