An annunciator, where required by this Code, shall be placed in a conspicuous location either inside or outside of and within 20 feet of the main entrance to the building. The annunciator shall indicate the zone from which an alarm has originated by means of a translucent rectangle which is electrically illuminated from behind when an alarm is received from the zone. The zone shall be identified by opaque lettering on the rectangular indicator which describes the location of the zone within the building. The lettering shall not be less than one- fourth inch in height. Provided however, that the annunciator may indicate by means of a diagram of the building with the zones identified by a light on the diagram corresponding to the area served by the zone. The diagram used must meet with the approval of the fire commissioner.
A separate indicator shall be provided for each zone. When a sprinkler system is also installed in a building requiring a fire alarm annunciator, sprinkler waterflow alarms shall be provided with an indicator on the annunciator separate from other zones. Indication on the annunciator shall be continuous until manually reset.
