• White finish.
• Installation available for flush or surface mounting (must be specified to the manufacturer).

🔢 Alarm Capacity (Number of gases):

• Supports 1 to 6 modules for medical gases and vacuum per alarm unit.

💡 Visual Graphics and Signals

• • Real-time pressure and vacuum reading via green numeric segment display.
  • High-visibility green LEDs for normal status.
  • High-visibility red flashing LEDs for high and low pressure alarm events.
  • Numeric display showing “ERROR” code for sensor disconnections or gas sensor crossing.
  • High-visibility green LED indicating the alarm is powered.

🚨 Alarm Events

• • • • Alarm for detection of high and low pressure events and low vacuum level in real time.
      • Alarm for detection of sensor signal interruptions (disconnection).
      • Alarm for detection of sensor switching or cross-connection of medical gas sensors.

🔌 Communications

• • • • 1 Relay port (dry contacts) per gas module contained in the alarm cabinet.
      • RS485 communication protocol over SERIAL connection to link with zone alarm groups and the SERIES 2 relay master panel (source equipment) from Arigmed.
