Main Features

Product Key Features


Provides an easy wireless environment for smart safety systems

It is a light/Siren system with built-in complex wireless communication technology (BLE, Wi-Fi, LTE). It can act as a gateway and link with nearby smart safety equipment without accidents. In the event of an emergency such as worker's SOS, it can spread situation notification to the surroundings, and it can automatically broadcast emergency evacuation announcements when it detects dangerous situations such as fire, facility collapse risk, and harmful gas leakage. 


High-power speaker 

It has a built-in high-power speaker of more than 100 dB, so it can propagate notifications without problems even in noisy environments such as construction sites. 

The speaker volume can be adjusted according to the field situation, and it can be selected and used by supporting eight types of sirens or voice notifications.

(Safety manager can change the sound source)


High luminance LED display

It is equipped with high-brightness LEDs so that you can identify warning notification situations from a long distance.

It offers four light mode (blinking, rotating, strobe, constant illumination) and can be used selectively to suit the characteristics of the site.


Easy installation method

It can be easily installed depending on the field situation such as cradle, screw, magnet, etc. It has built-in wireless communication technology, so only power needs to be supplied after installation.


Dustproof waterproof rating IP65

IP65's dustproof and waterproof rating has been obtained so that it can be used in barren outdoor environments such as soil dust and heavy rain.
