Best choice for
- Continuous text communication to employees at a fixed indoor location (alarm messages, production data, accident-free days)
- Easily readable at a distance: 76 mm characters, clearly legible up to approximately 38 metres
- Status at a glance via three colours (red, green, amber), for example red for an evacuation alarm
- Modern integration via Ethernet (AlphaEthernet adapter) — our recommended connection to link the display through the Alpha protocol to your network and applications
- Also backwards compatible with legacy systems via RS-232/RS-485 (for example linking with a fire alarm panel or another serial system)
Less suitable for
- Full-colour imagery, photos or video — this is a tricolour text display
- Long texts at once: 20 characters on 1 line per screen
- Outdoor installation — the 320C is intended for indoor and window installation (300 nits)
Typical applications
- Safety communication and accident-free days
- Production data and KPIs on the shop floor
- Alarm and evacuation messages
- Reception and gate messages for visitors or drivers

Frequently asked questions
Can I connect the Alpha 320C to my existing system?
Yes. The recommended solution is Ethernet via the AlphaEthernet adapter: this links the display directly to your network and your applications through the Alpha protocol. In addition, RS-232 and RS-485 are included as standard, so the display remains backwards compatible with legacy systems that still use serial communication, such as a fire alarm panel. Up to 80 messages are stored locally, with a built-in real-time clock.
Up to what distance does the text remain legible?
The characters are 76 mm high and remain clearly legible up to approximately 38 metres.
How much text fits on the screen?
20 characters on one line per screen (137 cm wide display). Longer or changing messages can be displayed in sequence.
Which colours does the Alpha 320C show?
Three colours: red, green and amber. Handy for distinguishing status, for example green for normal information and red for an alarm.
Is the Alpha 320C suitable for outdoor use?
No, the 320C is intended for indoor and window installation. For outdoor applications we recommend a display with higher brightness and an outdoor enclosure — feel free to contact us for advice.
