• In standby, the siren has seven different selectable, operating modes of the five LEDs of the
FLASH.
• Five different alarm sounds (selectable) and separate sound for fire alarm.
• It has two independent activation inputs, which operate with a positive or negative voltage
interruption and an independent activation input for fire detection.
• The siren will follow the alarm duration of the control panel. However, in case of interruption
of or short circuit of the cables that connect the siren with the Alarm Panel an alarm will be
triggered.
• Specifically:
- Sounds an alarm with duration five (5) minutes, if the power supply cables are cut-off (+12 V)
- Sounds an alarm with duration fifteen (15) minutes, if the TRIGGER cable is cut-off
- Sounds an alarm with duration five (5) minutes, if the power supply cables and TRIGGER cable
are cut-off simultaneously
• The siren, can be programmed so, when it starts operating will sound at low volume for
5 seconds and then the intensity will turn to normal level.
• The siren will sound an alarm of up to five (5) times in 24 hours (selectable). This time counts
from the first activation of the siren and the process is canceled just spend the 24 hours or if
there is siren power cut off for two seconds.
• The siren’s battery voltage is verified every hour, and when it drops below 11.5V (Low Battery),
the “FLT OUT” output (FAULT OUT) is activated. The “FLT OUT” output is also activated when
the battery is disconnected from the siren or when its voltage drops below 10 V (Battery Fail).
• When the battery voltage exceeds 13.8 V, charging is stopped to protect the battery from
overcharging.
• It has short circuit protection on the battery charging (of the cables) output. Also, it has
overcurrent and short circuit protection for the battery with simultaneous activation of the “FLT
OUT” output.
• It has protection against reverse connection of the battery poles with simultaneous LED
indication.
• When the siren is in standby mode and its battery voltage drops below 10.0 V, siren’s flash
stops flashing.
• Built in TAMRER switch to protect the siren from the opening the outer casing and the
detachment from the wall. The Tamper is provided with free contacts for connection to the
Alarm panel.
• The FSD has a built-in 3-axis accelerometer with adjustable detection sensitivity, which, in any
attempt to vandalize or change siren slope more than 45o, triggers an alarm to the siren and
simultaneously triggers the output “ALR OUT” ALARM OUTPUT).
• The FSD version has a built-in foam detector, which, in any attempt to sabotage the siren with
General Characteristics
Description
Self-powered and self-protected electronic siren with built-in FLASH 270°, in two shades (red
and blue), for easy detection of the area from which the alarm comes. It is an ideal combination
of stylish design and quality construction and is manufactured under the most, strict safety
standards. The outer cover is made of high-strength polycarbonate, suitable for outdoor use.
Inside it is protected by a metal cap made of galvanized sheet metal (in the Basic version) and it
has protection against opening the outer lid or detaching the siren from the wall. In addition, in
the IRIS PLUS / FSD version, there is a vibration detector to protect the siren from knocks and a
dual infrared foam detection sensor for protection against sabotage through foaming.

foam fire extinguishers, polyurethane etc., triggers an alarm to the siren and at the same time
also activates the ALARM output “ALR OUT”.
• When the siren’s supply voltage from the panel drops below 5.0 V, the “ALR OUT” output
(ALARM OUT) is activated, which can be connected to a zone of the panel, so the Control panel
is also triggered in case of alarm.
• The alarm duration from 3-G Sensor or foam detector is 90 seconds, and is independent of the
alarm duration of the control panel.
• Through “TC” input, with a very intelligent, automated process you can isolate the TAMRER
switch, the 3-G Sensor and foam detector and then you can open the cover of the siren to
change the battery or make service, without the siren sound.
• The built-in FLASH has five high brightness and low power LEDs, which are short-circuit
protected. The mode, the LEDs flash when the siren is in a standby mode is selectable.
• The FLASH continues to operate for 30 minutes after the end of the alarm, for easier locating
of the area in alarm (selectable). This function is canceled when the panel is disarmed or when
the battery voltage drops bellow 10.0V DC, provided that the TC input is connected to the
relative output of the alarm panel.
• “SIGN” Input, with selectable visual or audible confirmation of arming or disarming of the panel,
if remote control is used. This input activates the flash or the speaker, or both.

Installation
To install the siren, please follow the steps, as described below:
1.Select where you place the siren, this should be as high as possible, that the siren can be
easily viewed and secure.
2. Align the siren stand against the wall with the built-in spirit level, mark the fixing holes and open
them with an electric drill.
3. Fix the base of the siren to the wall using the existing brackets.
4. Pass the cable connecting the siren to the panel, from the hole which is at the base of the
siren. For maximum safety, prefer the passing of the cable in the inside of the siren to be
directly behind this hole.
5. Connect the siren to the panel, as explained in the connection terminals on page 5 and the
following wiring diagram.
6. When you finish cable connections, connect the battery to the siren. The siren can remain in
this condition until you finish the installation. The siren will start to operate normally only when
supplied with power from the alarm control panel.
Note:
When the power supply is initially applied from the panel to the siren, a short sound will
be heard as a confirmation that the siren has been activated.
7. Insert the inner cover and fasten it with four corresponding screws
8. Close siren’s external cover and fasten it with the corresponding screws.
Attention!
To power the siren from the alarm panel, you must, definitely, use wire
with diameter 0,5-0,75mm2. It is recommended to use cable 2x0,50 + 4x0,22 mm2.

The siren’s operation mode, in addition to the settings you should do, as described in the
following sections, has to do with the options of the wiring to the control panel, as detailed below.
1. Selecting the way in which the TAMPER of the siren will trigger alarm
The siren’s tamper activates the siren and the “TAMPER” output simultaneously. If you do not
wish the siren to be activated and only the “TAMPER” output to be activated, you can program
as described in the corresponding section on page 10.
The Tamper contacts end up to the “TAMPER” output of the siren. When the siren is screwed
to the wall and its lid is closed, this output is NC and becomes NO when the lid is opened
or the siren is detached from the wall. These contacts can be connected to any direct or 24-
hour zone of the panel (like NC or EOL zone, using EOL resistor), taking care to use the
correct polarity (COM & ZONE).
If you use an EOL zone, then, for greater security, place the EOL resistor in the siren at the
TAMPER ZONE output and in series with the cable as shown in the wiring diagram (page 6).
2. Remote test of the siren
The input “REM-BUS” is used to remotely control the status of the siren’s battery.
At this input you have to transmit 12.0V every time you wish to test the battery. By applying
the 12.0 V to this input, the “FLT OUT” error output opens to confirm receipt of the Remote
Test command. At the same time, the battery status test starts. If there is no problem with the
battery, the “FLT OUT” output will remain open for only 10 seconds and then be deactivated.
If a fault is detected on the battery, the “FLT OUT” output will remain activated after the end of
10 seconds and until the fault is restored. Once the fault is restored, another test will be carried
out and, if the test does not detect a problem, the “FLT OUT” output will be deactivated.
3. Power Supply of the siren
The + 12V inputs are for providing power supply to the siren and for charging the siren’s
battery. They are connected to the corresponding outputs of the panel, taking care to use the
correct polarity.
Attention!
For security reasons and for the proper operation of the siren, a battery must in any case be
used. In the case, however, that you want the siren to operate without a battery, you must
connect the red battery cable to + 12V input of the siren.
4. Select the siren’s indication activation mode
The TRIGGER (+ or -) inputs are used for the activation of the siren. Activation can be done
with one of the following two ways:
A. Interruption of positive voltage
Connect the “+ TRIGGER” input of the siren to the corresponding output of the panel or a
programmable output (PGM), which must provide 12.0V at standby and turn to 0 when an
alarm is activated.
B. Interruption of negative voltage
Connect the “- TRIGGER” input of the siren to the corresponding output of the panel or to a
programmable output (PGM), which must have 0V at standby and turns to Open Collector
or turns to 12.0V when an alarm is activated.
The siren follows the alarm duration of the table. However, in the event that the cables
connecting it to the panel are cut or shorted, the siren will sound an alarm of maximum 5
minutes.

5. Fire Alarm Activation Input
The “FIRE” input is used to activate the siren in the event of a fire alarm. It is activated by
applying a voltage of +12 V and the siren sounds with a special fire detection sound.
Attention!
If the “TRIGER” and “FIRE” input are activated at the same time, the “FIRE” input
will have priority
6. Bypassing the Siren’s Tamper - Removing the Lid
“TC” input (Tamper Control input) is used to deactivate the siren’s Tamper, when you open the
cover of the siren for service, without given an alarm. Connect “TC” input to a “PGM” output of
the alarm control panel, which provides 12 V at standby mode and goes to 0 when the panel
arm. The presence of 12V on this input disables the Tamper of the siren for 10 minutes.
In the Sigma Alarm panels, connect the siren’s TC input to a PGM, which must be
programmed as type 27.
7. Visual or audible indication input
The “SIGN” input is used when we want to have visual and / or audible indication of arming or
disarming the panel via the siren when, arming or disarming the system by remote control. It is
activated as long as there is +12 V at its input and is connected to a programmable output of
the panel (PGM) which is programmed accordingly.
In the Sigma Alarm panels, it must be connected to a PGM programmed as type 29.
8. Fault Output
The siren automatically monitors the battery status (Battery Self-Test) by dynamically testing
the battery, every hour when there is a voltage at the siren power input (+ 12V-) or, every five
minutes when there is no voltage. If, during the test, the battery voltage is lower than 11.5V,
we have a low battery voltage indication, and if the battery voltage is below 10.0V, we have a
battery failure indication. In both cases, the “FLT OUT” (Fault Output) output is activated.
The “FLT OUT” output is 0V and becomes Open Collector (OC) when the battery voltage is
low or the battery is damaged. Returns to standby again at the next test and if the battery volt
age rises above 11.5V or the battery is replaced with a new one.
This notifications are used to inform the user and / or the Central Monitoring Station, the
battery status of the system. A LED may be connected to this output or it may be connected to
the control panel, as shown in the siren wiring schematic.
For greater security, program the Control panel zone as a 24-hour EOL and connect the
terminal resistor in the siren.
9. Alarm Output
The “ALR OUT” (Alarm) output is activated when the siren triggers an alarm if its power supply
voltage from the Alarm panel is interrupted, or the foam, shock or 3-axis detector is activated.
The “ALR OUT” is activated simultaneously with the siren and is 0 at standby and becomes
Open Collector (OC) on activation. Used to update the system user and notify the Central
Monitoring Station for this event. You can connect it to a LED indicator or a zone of the panel,
programmed accordingly, as shown in the schematic that displays the siren connection.
For more safety, program the zone as EOL and place the EOL resistor of this zone inside
the box of the siren.
