Disabled audible alarm on fire alarm panel

What happened

During routine testing of the fire alarm, it was observed that the Fire Alarm panel was not emitting an audible alarm – there was only a flashing light present. The Chief Engineer together with the ETO inspected the fire alarm panel and found that a cable had been disconnected from the panel.

How the cable came to be disconnected could not be determined. There was no proper testing of the fire alarm system, nor any oversight or recording of maintenance.

Members may wish to check fire alarm panels any similar alarm equipment or warning systems to verify that all alarms audible and visual are functioning.
