WARNINGS AND LIMITATIONS
Our devices use high quality electronic components and plastic materials that are highly resistant to envi-
ronmental deterioration. However, after 10 years of continuous operation, it is advisable to replace the
devices in order to minimize the risk of reduced performance 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 opera-
tion.
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 environmental 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.
WARRANTY
All devices are supplied with the benefit of a limited 3 year warranty relating to faulty materials or manufacturing defects, effective from the
production date indicated on each product.
This warranty is invalidated by mechanical or electrical damage caused in the field by incorrect handling or usage.
Product must be returned via your authorized supplier for repair or replacement together with full information on any problem identified.
Full details on our warranty and product’s returns policy can be obtained upon request.

GENERAL DESCRIPTION
The wireless audiovisual sounder base is a device that activates its output when ordered so by the control panel in the event of fire alarms.
The activation command is sent from the control panel to the base sounder through the wire to wireless translator interface module and other
possible wireless expander modules. Communication between the audiovisual sounder base and the translator / expanders is obtained
through the “Sagittarius” wireless, analogue-intelligent bidirectional protocol.
Wireless sounder base is designed to act as a supporting mean for the installation of Sagittarius wireless detectors.
GENERAL OVERVIEW
VISUAL LED INDICATOR
The wireless audiovisual sounder base is equipped with a bicolour red - green LED (picture 3) that provides visual indication for functional
conditions and battery levels as indicated in table 2.
DEVICE’S POWER SUPPLY AND LINKING
The linking operation permits the configuration of the wireless audiovisual sounder base on the wireless system.
The linking operation described below does not change if made directly from the wire to wireless translator module’s interface or from the
Wirelex PC configuration program.
1) Move the “Link-program” switch to position ON (picture 4).
2) Insert the secondary battery into its housing (picture 5).
3) Insert the primary battery into its housing; the visual LED indicator switches on accordingly (see “Power up” in table 2 and
picture 6).
Ensure that both battery’s polarity are correct!!!
4) When the wire to wireless translator (by itself or piloted by the Wirelex) is searching for a new device for linking, move the “Link-program”
switch to position 1 in order to initiate communication with the translator module (picture 7); the visual LED indicator switches on accordingly
(see “Programming and linking to the system” in table 2).
IMPORTANT NOTE!
Programming is considered to be completed successfully only if there is an indication of programming success on the wire to wireless trans-
lator or on the window of the Wirelex program.
If the linking and programming operation fails, check if mistakes were made with the wire to wireless translator
or the Wirelex, remove the
batteries, change the switch over ON / 1 alternatively a few times in order to discharge the internal capacitor and then start again from point
1) re-performing the linking procedure.
COMMUNICATION QUALITY ASSESSMENT
It is possible to assess the wireless communication quality between the wireless audiovisual sounder base and the wire to wireless transla-
tor
/ wireless expander
by using a testing feature built in the device.
After a successful linking operation, by changing over the “Link-programming” switch on the ON position, the device’s LED will start blinking
according to table 3.
Always remember to reposition the switch to 1 after the assessment operation: device will NOT work operatively while the switch
is changed over the ON position.
DEVICE’S PLACEMENT
For specific information regarding detector and device’s spacing, placement and special applications refer to your specific national stand-
ards.
It is strongly advised to mount the wireless audiovisual sounder base as far as possible from metal objects, metal doors, metal window
openings, etc. as well as cable conductors, cables (especially from computers), otherwise the operating distance may greatly drop. The
audiovisual sounder base should not be installed near electronic devices and computer equipment that can interfere with the reception’s
quality.
1) Select the position of the audiovisual sounder base before installing and fixing it.
Verify, from that position, that the communication between the device and the wire to wireless translator / wireless expander is
correctly established and working (see the COMMUNICATION QUALITY ASSESSMENT paragraph).
2) Install and fix the sounder base in the selected position with the provided screws (picture 8).
3) Select the audiovisual sounder’s base output’s tone and volume (see the OUTPUT SETTING paragraph)
4) Insert the wireless sensor onto the sounder base, then secure it by turning it clockwise.
OUTPUT SETTINGS
Output’s characteristics when the wireless audiovisual base sounder is activated (tone and volume) can be selected through the DIP switch
selectors located in the inner area of the sounder base (see picture 9).
In order to change over the switches use the tip of a pen or a little screwdriver.
For the selection of the output settings refer to picture 9, table 4 and table 5.
BATTERY FAULTS
If a battery fault condition is detected on the wireless audiovisual base sounder, a fault message is sent to the control panel via the wire to
wireless translator / wireless expander.
This kind of fault condition is locally signaled by the sounder base’s visual LED indicator (see table 2).
TESTING
In order to test the functionality of the installed wireless audiovisual sounder base, the following test must be performed: activate an alarm
condition on the control panel (by a call-point or sensor in the installed system): the control panel will transmit an activation message to the
device via wire to wireless translator / wireless expander and activate the sounder base. After each test the device must be reset by the
specific command on the control panel or on the wire to wireless translator (see the RESET paragraph). If the test fails check whether the
batteries are charged, if mistakes were done previously or even if the system is activated. If the wireless audiovisual sounder base
function-
ality is hopeless, send back the device to your distributor for repair or substitution.
All devices must be tested after installation and, successively, on a periodic basis.
