BUilding Operations Function

1.8.1. Building Zoning The building is divided into several zones, dependant upon the physical arrangement of the building. 1.8.2. Building Operation 1.8.2.1.

Normal Operation

OCR Call Station The OCR call station allows the building supervisor to broadcast an announcement to any zone or combination of zones within the building. The destination zones can be selected at the zone selection keys at the call station. The status of the zone is indicated by an LED when that zone is selected. The zone selection keys operate in latching mode. The announcements, to the selected zones, can be initiated by pressing the 'press to talk' key at the call station throughout the announcement. The 'press to talk' status LED indicates the status of the announcement. . The pre-recorded announcement can be activated from the pre-defined keys at the OCR call station, and can be scheduled to be played at specific times. The background music can be activated by the 'Back Ground Music' key, which operates in latching mode and the status of the background music key is indicated by an LED. Reception Call Station The reception call station allows the operator to generate announcements to the associated areas. The call can be initiated by pressing the 'press to talk' key at the reception microphone throughout the announcement. The status of the reception call station will-be given by means of LED. Announcements from the reception call station can override the OCR announcements. 1.8.2.2. Emergency Operation In the event of emergency, i.e. fire, the PA system will receive fire alarm signal from the fire alarm system to initiate the pre-recorded emergency announcement to peoples and staff in the building. The PA system will address all zones within that building with the emergency message. In the event that the PA system fails to receive the fire alarm signal, the emergency messages can be activated/ deactivated the OCR call station. The emergency announcement can be overridden by an announcement from the OCR and reception call stations. 1.8.3. Priority The priority of announcements in the building is as follows:

2.1. Interfacing to Fire Alarm System The PA system requires the fire alarm signal from the fire alarm system at building to initiate the pre-recorded emergency announcement. The means of interface is a single dry contact from the fire alarm system to the alarm input at the PA system cabinet at control room. The contact is normally close, which means that the contact will be opened when the fire alarm system sends alarm signal to the PA system and the contact will open when there is no fire alarm signal from the fire alarm system. In the event that the fire alarm system fails to send the alarm signal to the PA system, the operator can either initiate the pre-recorded emergency announcement or make a live announcement manually at the OCR call station for the building, the broadcast may be made manually from the appropriate administration office. Cable and Wiring 3.1. Loudspeaker Cable The loudspeaker cable connected from power amplifiers to the loudspeakers operates at 100 volts. The generic type of cable shall be .8. The building is divided into several zones, building.
