Sirens are divided into two different groups: outdoor and indoor, differing in their design and size.
Each group features different signalling methods: optical or acoustical.
Sirens are either powered directly from a control panel, or by a separate power supply operating in the alarm installation.
Some of our sirens are equipped with emergency power supply (battery) in case they’re cut off from alarm installation. This security feature proves useful when sirens are installed in easily-accessed places.
Enclosures of our sirens are made of high quality polycarbonate. This material is used for example in car lamp casings or police shields.
The devices in our offer are resistant to high and low temperatures, strong wind, humidity or UV radiation, as well as to attempts of intentional damage.
Each model offered by SATEL features tamper protections which detect attempts to open the enclosure or detach the device from the ground. Some models detect attempts to silence the alarm device with mounting foam.
We use a layer of resin to protect electronic elements sensitive to weather conditions in alarm devices intended for outdoor use.
A metal shield is a supplementary protection. Shields protect the interior of the alarm devices against any forceful attempts of destroying them.
