Medical Gas Alarm Unit for Real Time Pressure Monitoring and Safety

The Medical Gas Alarm Unit by Tecnomed is an essential safety device used in hospital medical gas pipeline systems to continuously monitor gas pressure levels. When gas pressure values go beyond preset thresholds, the unit provides audible warnings and transmits real-time information to the central automation system.

Dual Alarm for High and Low Pressure Detection

For each connected gas line, the unit can generate:

• Low Pressure Alarm
  A high-priority alarm indicating that the gas pressure has dropped below the critical limit.

• High Pressure Alarm
  A high-priority alarm signaling that the gas pressure has risen above the safe operating level.

These alarms ensure that both under-supply and overpressure risks are detected instantly, protecting patients and sensitive medical equipment.

LCD Display for Local Monitoring

The Medical Gas Alarm Unit features an integrated LCD screen that displays:

• Real-time gas pressure values

• Alarm status notifications

• Current limit settings for each monitored gas

This allows on-site personnel to visually verify gas status without accessing central control panels.

Communication with Automation Systems

The unit is equipped with RS485 / Modbus communication capabilities, enabling it to transmit:

• Pressure values

• Alarm triggers

• Threshold settings

to the building’s central automation or SCADA system, allowing centralized tracking, remote supervision, and data logging.
