1) What is PA /VA System and what is the Purpose Of PA Systems?
PAVA stands for Public Announcement and Voice Alarm/Evacuation System.
The Purpose Of PA system is to achieve Speech and Announcements for emergencies as well as general announcements.

2) List 4 common Equipment’s which Are Used In PA System.
1) Microphone 2)Amplifier 3) Speakers 4) Voice Evacuation controller

3) What is the difference between Mixer Amplifier and power amplifier?
Mixer Amplifier : Provide Power to speakers and also have line level inputs like Aux/USB and and Multiple microphone inputs as well as a priority input.
Power Amplifier : Only Provide Power to Speakers typically over a 70V/100V line and need a pre-amplifier or mixer for line lever and microphone inputs.

4) Can we combine BGM and Emergency Evacuation Public address in one system?
Yes it is possible for small as well as large systems. For small systems using mixing amplifiers without controllers or using a power amp with a mixer /preamplifier enables us to use Back ground music via a local or internet source as well as voice evacuation messages via a paging microphone. For large systems it is a bit complex and is achieved by a system design in which separate amplifiers or EMC bypass is used to have a common BGM and EVAC system.

5) Can we use a remote paging source if we do not wish to use the microphone for announcement?
Yes, you can connect the EPABX (any SIP enabled communication system) to the PA system and use the SIP protocol over IP phones to make an announcement either via IP phone or softphone (Mobile)

6) What if we have multiple local Volume controls in the system and for Emergency voice evacuation message we wish to bypass the volume controls such that the announcement is heard even if volume control is switched to off ?
Yes, it is possible and recommended to use volume controls which have “forced insertion” function. Typically a 24V power line is used to bypass the volume controls and achieve forced insertion.

7) How to ensure automatic voice evacuation messages in a PA system?
Typically, the PA system is linked to the Fire Control Panel (FACP) for automatic triggering of voice evacuation message in case of fire and emergency. For this, dry contacts of the FACP or output type modules in case of an addressable FACP are used. These switching type (No/NC) contacts are connected to the PA system controller or an auto evacuation message box which in turn plays the message automatically over the existing PA network speakers.

The Need for a custom designed FTTH home ELVDB.

Coalesce is a Residential Data Voice and Video Distribution box, which makes Residential Structured Wiring Easy and Fiber to Home Ready. It’s a ready to use ELV Data Voice Video DB to be installed inside apartment, with ready conectorisation which can be used for all kind of network like Fiber to Home or Fiber to Shaft or Active Ethernet based.

There are many unique feature of Coalesce ELV DB as compared to a traditional DB The Accessories and complete product is designed as per latest technology like FTTH and as per TIA standards for Structured Cabling.

"The primary Issue with our Indian industry is that often professional and standardised product get compared with locally manipulated products in which a electrical contractor buys a fabricated DB separately and then tries to fit krone modules and locally made power supply"

Such jugad products often land with above issues at site and you can see many such examples of projects and even in ultra-premium residential apartments.

Please find below link for video of the product to understand it easily and see the difference https://drive.google.com/file/d/1RszNIjqi2nXA1DlHJpH28UGqqrSXhRUa/view?usp=drivesdk

1. What are T-568A and T-568B wiring standards, and how are they different?
T-568A and T-568B are the two wiring standards for RJ-45 connector data cable specified by TIA/EIA-568-A wiring standards document. The difference between the two is the position of the orange and green wire pairs. It is preferable to wire to T-568B standards if there is no pre-existing pattern used within a building.

2. What is RJ stands for?
RJ stands for Registered Jacks. These are used in telephone and data jack wiring registered with FCC. RJ-11 is a 6-position, 4-conductor jack used in telephone wiring, and RJ-45 is a 8-position, 8-conductor jack used in 10BaseT and 100BaseT ethernet wiring.

3. What is the Category Rating System?
Electronic Industries Association (EIA) developed the TIA/EIA-568-A standard, which specifies wiring and performance standards for Unshielded Twisted Pair (UTP) cabling. Category Rating System specifies the definition of performance categories for 100 ohm UTP cabling system.
Category:3 specifies the twisted pair cable and connecting hardware that can support transmission frequency up to 16MHz, and data rates up to 10Mbps. This is primarily used in telephone wiring.
Category:4 specifies cables and connectors that supports up to 20MHz and data rates up to 16Mbps. With introduction of category 5, this is a rarely used category.
Category:5 specifies cables and connectors that supports up to 100MHz and data rates up to 100Mbps. With 100BaseT Ethernet today, Category 5 is a widely used cabling system that matches todays high-speed data requirements.
4. What is UTP Cable?
UTP stands for Unshielded Twisted Pair. It is the cabling system with one or more pairs of twisted insulated copper wires contained in a single sheath. It is the most widely used cabling system in telecommunications and data communications environment today.
CR80 ID cards are more commonly known as credit card-sized ID cards as they are the same size as a standard credit card.
CR80 cards measure 2.13″ x 3.38″ (54 mm x 86 mm), with a typical thickness of 30mil. CR80 cards are a popular choice for ID credentials because of their size and feel familiarity.
The standard thickness of a CR80 is 30mil, though you may find slight variations in terms of thickness or “mil” of the card.
*Mil = .001 or an inch.
CR80.10 = 1/100 inch thick.
CR80.20 = 2/100 inch thick.
CR80.30 = 3/100 inch thick.
The CR80 dimensions loosely follows the ISO/IEC-7810 ID-1 specification. Other (less common cards sizes) CR79, CR90, and CR100 are also available.
