The public address system shall be also used to broadcast paging live messages and mute the Background Music (BGM).
The public address system shall receive control signals from fire alarm system in case of fire.
Voice evacuation messages and alarm tons shall be broadcasted by the Public Address system using the appropriate hardware and software modules required for interfacing between the Fire Alarm (FA) and the PA systems.
Interface equipment shall be included in the public address system to communicate with the FA system for receiving command of announcements. Supervisory signals shall be sent from the PA to the FA to confirm healthy situations or indicate fault.
The public address system main component as the following:
- Audio Matrix and workstation
- Preamplifiers (if required), power amplifiers
- Program sources (CD player, double cassette, tuner and paging microphone)
- Loudspeakers
- Monitor module panel
- Racks
Fire Alarm System
The proposed solution of fire alarm system shall have main fire alarm control panel FACP, and this panel shall include and cover all design requirements.
The provided fire alarm system shall be suitable for type of occupancy as defined by international standards and as per the local fire Authority for each country.
The fire alarm system shall be used to detect early start of fire in any location in the project and initiate the appropriate annunciation, alarm, interlocking and counter measures commands as described in the project design criteria.
The Fire Alarm system shall supervise all the functions of the equipment and devices including the connected safety related systems such as firefighting monitoring and control equipment, etc.
Fire Alarm solution shall consider Audible alarms, voice evacuation message and visual strobe lights will be used for annunciation.
The Design of Fire alarm system shall be interfaced with Public Address system, Elevators, smoke control equipment, emergency power systems and all other related systems.
Also, design drawings/documents shall include all necessary hardware and software for integrated complete and operable system in accordance with the requirements of the project.
Security System
CCTV
The hybrid based (IP / Analogue) CCTV system shall be used for security surveillance having color video cameras.
The CCTV System shall cover project areas as indicated on the detailed drawings which prepared based on the project technical specifications.
The proposed solution of video cameras locations shall be at suitable positions, which make them cover the intended fields of vision.
Also, during the design stage, it’s to be verifying spaces for equipment, based on actual dimensions of equipment furnished.
CCTV system shall be interfaced with security systems, and all other related systems.
INTRUSION SYSTEM
The intrusion detection system is a security system, which shall control access to certain areas and give alarm in case of unauthorized activities in order to achieve maximum-security in the project.
Intrusion Detection System shall be based on hardware (panel/s, detectors, panic buttons, interfaces, servers, workstations, printers, etc.) and related software.
All devices of the system shall be addressable to be monitored and controlled.
The optimum solution will provide a totally integrated system in case of having multi-vendor equipment and interfacing between the different components of the system and the other related systems.
MASTER CLOCK SYSTEM
