The ZSE50 Siren & Chime gives you the freedom to customize alerts with your own sounds—whether it’s a friendly door chime, a unique alarm tone, or a fun notification for special events. In this guide, we’ll walk you through everything you need to know to get started: which audio formats the device supports, how many sound files you can store, and the step-by-step process to upload or remove them. By the end, you’ll be able to fully personalize your siren and chime to suit your home’s style and needs.
Supported File Types & Recommendations
The ZSE50 Siren & Chime can play audio saved in .mp3 or .wav format. For smooth playback and faster uploads, we recommend:
-
.mp3 files at a bitrate of 128 kbps or 192 kbps – this gives you clear sound without making the files too large.
-
Keeping each file under 1 MB – short chimes or alerts usually end up in the few hundred KB range, which helps you store more sounds on the device and avoids long upload times.
Following these guidelines will make sure your sounds work well and don’t take up unnecessary space.
- Max number of playback sounds: 50
- Internal file storage: 16 MB
- Supported file types: .mp3, .wav
Important note: The flash drive is 16MB - this may limit the number of files. If you are uploading smaller files that total less than 16MB, then the limit is 50 files then. If you're loading larger files, the number of accepted files will be lower (limited to 16MB).
Transferring Files to the Siren
