Condition Tones Priority Input

PA 800 + 5 Hz with ½sec. mark/space ratio

1 Manual

GA. 500-1200Hz-500Hz in 2 Manual & auto

-

113

3 sec. cycle

Process Alarm Message

Pre-recorded messages

3 Auto

Emergency announcement

4 Manual

Normal PA Two tone chime 5 Manual

Telephone Paging One tone chime 6 Manual

Tests

Steady 7 Manual

The unit priority (for Emergency Announcement and Normal Paging) shall be in the following descending order

� Control Room in the Terminal building � Security in the Terminal � Fire Crash Rescue

The priority system is required to ensure efficient usage of the PA System. Tone priority as specified above shall be easily changed/interchanged if and when required an input for higher priority shall automatically stop/override an existing lower tone and activates the higher priority tone.

When Emergency PA function e.g. Abandon Facility, (Priority Level 1), is manually activated during presence of a Fire and Gas alarm (Priority Level

2), the Fire and Gas alarm tone shall be overridden for the duration of the Abandon Facility alarm tone. (This feature shall apply to all levels of

alarms).

When an Emergency Announcement (Priority 4) is selected during the presence of any higher priority tone alarms, the tone alarm shall be

reduced to a lower audio level, after time delay, for the duration of the

announcement.

A timer shall control the time delay, which shall be an integral part of the main/central PA equipment. It shall be possible to vary the pre-set delay

from 1 to 30 seconds.

The tone muting shall be automatically controlled for a period of approximately 30 seconds and activated by relay contacts from the

System.

Tone muting level shall be adjustable from 6 dB to infinity. Permanent muting action shall be prevented.

-

114

When a higher priority alarm condition arises while the Emergency Announcement is being used (during lower priority alarm), the higher priority alarm shall override the Emergency Announcement and continue to broadcast the higher priority alarm tone for the pre-set time as stated

before the Emergency Announcement function can once again be used.

The selection of normal paging/test function during an alarm annunciation shall not be possible except during the localized Process Alarm. During localized Process Alarm, normal paging shall still be possible to other

areas except the affected area(s) and the sleeping areas.

The normal paging access is from PA control panels or the telephone extensions. This priority arrangement is for ensuring that the activated alarm having the highest assigned priority level is broadcasted/annunciated and that lower priority alarms are muted. Hence, this priority arrangement assures that only the most urgent alarm will be

heard at anyone time.

3.2 Alarm Sequence

The alarm pattern for the visual and audible GA and PA shall be unique and in accordance with the table below:

Alarm Signal

.25 :System Description

5.2.1 Under normal operating conditions, inverters share the AC load, inverters derives its DC power from the Float/Boast chargers, while the Battery remains in float across the output of the chargers. The chargers

in turn draw its AC power from the commercial AC mains.

5.2.2 In case of interruption to AC mains, the inverters get the DC power from the battery, so that the AC output of the inverters remains

uninterrupted. The battery is discharged under this condition.

5.2.3 When the AC mains is restored, the chargers will feed the inverters again and at the same time supply charging current to battery

to boost and restore the full charge condition. At the end of charging cycle , the chargers revert automatically to floating mode.

5.2.4 In case of failure to AC output of the inverters, the static switch

automatically by pass the load to the AC mains.

5.2.5 When the AC load is fed directly from the AC mains, the voltage across the load should be regulated to 230V±2%, which requires a

separate Static AC regulator of full capacity to be provided. The load should be reverted to inverters automatically or manually after rectifying

the fault.

5.2.6 Manual Bypass switch is required to bypass the inverters and transfer the AC load manually to the AC commercial.

5.2.7 The system should be fully redundant. It should consist of more than one inverter, chargers connected in parallel, two battery banks of

backup, bypass equipment minutes 30 adequate capacity to cater forand static voltage regulator of full load capacity.

5.2.8 The whole system should be flexible to expansion.
