Two optical sets placed on the sides of the housing increase the visibility of the glowing device, even from a considerable distance, including in daylight. One of three types of modulated sound signaling with an intensity of 120 dB is available for selection. The signaler&#8217;s housing is made of polycarbonate, ensuring high mechanical durability and an aesthetic appearance that remains unchanged over the years. The simple yet attractive design of the housing fits perfectly even on modern facades. The device is equipped with anti-tamper protection to prevent opening the housing or detaching it from the wall, and the internal cover made of galvanized steel provides additional protection for the electronic board and transducer against mechanical damage. Thanks to appropriate impregnation, the electronic system is also resistant to harsh environmental conditions.<\/p>\n<h3>Application<\/h3>\n<p>The SP-4003 acoustic-optical signaler is available in
