What type of alarm(s) shall activate when the backup or lag compressor is running?

When the backup or lag compressor is running, it is essential for there to be an alarm system that ensures alertness to potential changes in the operational status of the medical gas system. A local alarm system serves this purpose effectively by providing immediate notification to personnel in the vicinity of the equipment.

Local alarms are designed to indicate specific faults or operational statuses in the immediate environment, allowing for quick response and maintenance actions. Since the backup or lag compressor is crucial for maintaining the functionality of the medical gas supply, a local alarm provides real-time awareness for any personnel nearby to monitor the operation.

This prompt notification can be critical in preventing potential risks associated with medical gas supply interruptions or failures, thus enhancing safety in facilities that rely on these systems. Other types of alarms, such as area, main, or source alarms, generally provide alerts over broader regions or are tied to different signaling systems, which may not offer the immediate response necessary when a lag compressor is activated.
