Customer Specific External Alarms

The optional SAU monitors and controls customer equipment. The SAU can handle up to 32 external alarms.

The SAU is not included in the cabinet but is installed in the DF-OVP, outside the cabinet, and connected to the SCU.

An alarm can be generated by two alarm conditions:

Closed loop condition, called Normally Open (NO) NO means that an alarm is triggered when an open switch is closed.

Open loop condition, called Normal Closed (NC) NC means that an alarm is triggered when a closed switch is opened. NC is the default alarm condition.

The customer can configure the alarm condition.

The Support Alarm Unit (SAU) is an alarm and connection unit that is externally mounted in a distribution frame that also includes Overvoltage Protection (OVP) for external alarms and transmission.

Dependability

The RBS is designed for a technical lifetime of 20 years (24-hour operation).

The following preventive maintenance conditions must be fulfilled to guarantee the availability of the

RBS :

Fans : The fans must be inspected (and cleaned if necessary) every year.

Ericsson recommends

replacing the fans every 10 years. Air filters : The air filters must be regularly inspected and cleaned (interval

depends on the environmental conditions at the site.Ericsson recommends

replacing the filter once a year.
