Wireless outdoor siren Ajax StreetSiren DoubleDeckThe installation of a street siren is needed for properties with an increased risk of intrusion to notify of unforeseen situations. The outdoor siren is used to prevent the intrusion of strangers into the territory with a loud sound and to alert others about other types of alarms — fire, leakage, etc.
The principle of operation of a street siren and the advantages of using the deviceThe principle of operation of a street siren resembles the operation of a speaker; the membrane vibrates after the current is applied due to magnetic vibrations — sound vibrations are created. The frequency and sound level of the siren depends on the generator and the characteristics of the membrane. The effect of attracting attention is enhanced by the operation of a device equipped with light and sound indicators. A siren that reports an alarm only by light is not always effective — from afar, the light of the device may not be noticed.
Depending on the purpose of the detectors, the following types of devices are distinguished:
- light annunciator;
- sound detector for signaling;
- information board.
The types of sirens for alarms are as follows:
- Type of installation — outdoor or indoor.
- Type of notification — sound, light, light and sound.
- Power type — 12V, 9-14V, 24V, 220V.
