Depending on the application, please choose the appropriate type:
An electronic horn is ideal for reproducing a classic buzzer sound.
An electronic multitone siren can generate a wide range of alarm tones. A big advantage is also that they consume little power and can even be powered by a battery.
An electronic multi-tone siren with recording capability also records and stores self-recorded content and plays this back with unsurpassed clarity at any sound level. The alarm tone demands your attention but the recorded message emphasises what is going on: e.g. 'leave this area immediately, biological danger'.
A motor siren generates one particular type of alarm signal via a powered motor, which is highly suitable for bridging medium to large distances.
A mechanical bell produces the classic 'tring' sound.
The relative humidity indicates the ratio of water vapour in the air to the maximum possible amount of water vapour. A specification of relative humidity of 90% at 20°C, indicates that you should not use the device in an environment with an air humidity higher than 90% and this at a temperature of 20°C.
The ingress protection ratings are defined by international standard IEC 60529 which classifies the degrees of protection against intrusion of solids and liquids in electrical enclosures. The first digit indicates protection against penetration of solid objects. The second digit indicates protection against penetration of liquids.
EN 54-3: Complies with European standard which checks the specifications, noise level values and actual emission characteristics of the sirens.
UL: complies with US signalling regulations
cUL: complies with Canadian signalling regulations
GOST-R: complies with national standards of the Russian Federation
EAC: complies with Euro-Asian regulations
MED: complies with marine regulations
VDS: German alarm quality requirements (for fire and police services).
CEBEC: A private Belgian rating label for the quality assurance of electrical appliances. It stands for "Comité Electrotechnique Belge/Belgisch Elektrotechnisch Comité". CEBEC marking is not obligatory, but it helps to get electric installations or equipment certified faster.
