Final answer:
Annunciators should be installed where they can be seen and heard easily, not necessarily where they are easiest to service, to ensure quick communication of issues.
Step-by-step explanation:
The statement that annunciators should be placed at a location that is easiest to service is false. Annunciators, which are alarm panels that monitor and provide a visual display of the operational status of various systems, should actually be installed at a location where they can be seen and heard easily by personnel who need to be alerted in case of any malfunctions or emergencies. This often means placing them in areas that are frequently manned or in central locations. While ease of service is important, the primary goal is to ensure safety and the quick communication of any issues. Regular maintenance can be performed with annunciators in accessible locations provided they are planned into the design, but their primary placement should consider visibility and audibility for effective monitoring
