SGO-Pgw voice sounder with visual alarm device

Signalling device with voice messages is intended for signalling a fire alternately with acoustic signal and voice message signal. Additionally, the signaling device generates a flash optical signal. SGO-Pgw voice sounder with VAD is intended for indoor applications.


The signalling device has a plastic casing that contains electronic components. The casing consists of three parts: a body with a speaker installed, a cover with a printed circuit, and a base that can be mounted on a wall / a ceiling or directly to a PIP-3AN box.
Cover contains:

  • power supply connection,
  • connection for a  WSD-1 switch,
  • micro USB connection,
  • potentiometer for volume adjustment.

The power supply connection has three terminals marked as “+1”, “+2”, “GND”. The USB connection makes it possible to copy messages from a PC to the internal memory of the device.

The signalling device can emit up to 18 patterns of acoustic signals; it is also possible to choose the “no acoustic signal” option. Additionally, a flash signal is generated by the optical element during the alarm.

By default, the siren has three messages memorized in its memory and a set fire siren.

Cooperation with WSD-1 audible signal switch:

When the signalling device has to be deactivated locally (acoustic part), the user can use the attested sound signal switch WSD-1. The signalling device has a connection block for connecting the switch. On connecting the WSD-1 switch, pressing the key deactivates the sound signal of the device (the optical part remains active) . The condition is active as long as voltage is present on the terminals of the device. The active condition of the switched is indicated with the LED on the switch key.


The WSD-1 switch is powered directly from the sounder (it does not require external power supply).


The SGO-Pgw sounder with VAD is available in 4 varieties, which differ in the arrangement of the optical element and the color of the flash generated.

Varieties Description
SGO-PgwA Red light, lens positioned centrally
SGO-PgwB Red light, lens positioned offset to the edge of the housing
SGO-PgwA/śb White light, lens positioned centrally
SGO-PgwB/śb White light, lens positioned offset to the edge of the housing


For SGO-PgwA/śb and SGO-PgwB/śb varieties Certificate of Approval is not valid!


To open the signalling device: screw out the screw locking the base, turn the shade anticlockwise while holding the base, then separate the shade and the base.


To close the signalling device: fit together the markers. After that put together the device and turn in the direction marked with an arrow (the sequence in the drawing). On closing, lock the base by screwing in the locking screw.

Installation recomendation:

SGO-Pgw voice sounders with VAD should be connected to Fire Alarming System by means of junction boxes featuring fire resistance (PIP-3AN is recommended). The junction box should be mounted to a ceilling / wall, which should also have required fire resistance. In the case when for an esthetic reasons installation of signalling device directly on PIP-3AN junction box is impossible, it is admissible to install a signalling device on substrate that does not have required fire resistance, however the junction box must be mounted on substrate having required fire resistance (e.g. a situation, in which a PIP-3AN junction box is mounted to a ceiling having E90 fire resistance, while the SGO-Pgw signalling device is mounted on a suspended ceiling).

Connecting the supply voltage to the terminals triggers the generation of the appropriate alarm and the output signal.


Providing the supply voltage to: input +1 will play the message K1.mp3, input +2 will play the message K2.mp3, inputs +1 and +2 will play the message K3.mp3.

Control – devices network

SGO-Pgw voice sounder with VAD can be used to build networks of synchronously operating signalling devices (acoustic and optical part). Signalling devices in the network do not require addressing – no need to programme signalling devices in the master/slave mode. There is also the option to automatically copy messages to all the signalling devices present in the network – a feature which is useful for updating message content.


For proper operation of the bus, 120 Ω resistors must be applied at the ends of the bus.
The maximum number of signalling devices operated in one network is 10.
The maximum length of the bus should not exceed 200 m

It is recommended to use the USB cable for alarm devices.

To work properly, the signaling device requires a configuration file and * .mp3 files with the content of messages. In order to copy files with recordings, disconnect the supply voltage from the device terminals. Then connect the device to the USB port of the PC / laptop with a USB A / micro USB cable (data transmission function required). After connecting the cable, the siren will be visible in the operating system as a mass storage device. Then, copy the files with sound recordings to the siren.

The user should remember to keep the nomenclature of file names with names recognized by the signaling device, i.e. the first message “K1.mp3”, the second message “K2.mp3”, etc.

The next step is to modify the configuration file. In this file, the user selects the siren number as well as the auto-update option. User can choose 1 of 18 siren patterns or no siren.

In case of loss of the configuration file, the file is available for download at after logging in to the MY ACCOUNT.
