1. GENERAL
The SPL-5020 outdoor siren is designed for application in burglary and panic alarm systems. The
signaling function is performed in two ways: optically (by lamp blinking) and acoustically (with
a modulated high-volume sound signal). The source of light is a 5W/12V incandescent lamp, while the
sound signal is generated by means of a piezoelectric transducer. Electronic circuit of the siren is
made in SMD technology and impregnated against adverse effect of weather conditions, which
ensures a high reliability of the equipment. As the outer shell of the SPL-5020 is made of PC LEXAN
high-impact polycarbonate, it features a very high mechanical strength and guarantees esthetic look
of the equipment even after many years of service.
2. INSTALLATION
The SPL-5020 siren should be mounted on flat surface, at a place as much inaccessible as possible
so that the risk of tampering is minimized. The siren must be attached to the surface by means of
screws and expansion plugs. In order to take off the cover, remove the retaining screw and lift it by an
angle of approx. 80°. Be particularly careful when dismounting and remounting the inner sheet metal
cover.
Note: Make sure there is a suitable distance (minimum 2.5cm) between the upper edge of the siren
base and the ceiling or another element restricting the mounting position from the above.
Otherwise, replacement of the cover may be impossible.
After installation of the siren, it is recommended that the mounting holes as well as the cable inlet be
sealed by means of silicone compound.
3. CONNECTION
The SPL-5020 siren can be used with any source of alarm signal which in emergency situation
generates 12V direct voltage on its alarm output(s) or whose output will be shorted to the common
ground (0V). The acoustic signaling is controlled by the SA input, while the optical signaling – by the
SO input. The kind of triggering signal is to be set with the JP1, JP2 jumpers.
