Verbex VT-APS103  Wireless Indoor Sound and Light Siren Portable Siren

• Wireless: This is a major selling point. Instead of running wires through your walls or across a room, this siren communicates with the main alarm panel via a radio frequency (RF) signal, likely 433MHz, which is a common frequency for home security devices. This makes installation and placement much more flexible. You can place it in a central location, a basement, or an upstairs hallway without any hassle.
• Indoor: This means the siren is designed for use inside a building. It's not built to withstand outdoor elements like rain, extreme temperatures, or direct sunlight. Using it outdoors could damage the unit and void the warranty.
• Sound and Light Siren: This siren has both an audible alarm (the "sound") and a visual one (the "light").
• Sound: It emits a loud, high-decibel alarm tone to alert occupants and deter intruders.
• Light: It has a built-in strobe light that flashes, adding a visual element to the alert, which can be particularly useful for people who are hearing-impaired or in a noisy environment.
• Portable Siren: While it's still a stationary device once set up, the "portable" aspect likely refers to the ease of its installation and relocation due to its wireless nature. You can easily move it to a different room if your security needs change.
• Compatibility: The VT-APS103 would need to be paired with a compatible Verbex alarm system, most likely a GSM or WiFi-based system that operates on the same wireless frequency.
