A siren tells people something is wrong. A voice tells them what to do and where to go. This public address system in Hyderabad does both jobs in one network. It carries daily announcements and, when linked to the fire panel, evacuation messages. Our fire alarm systems page explains the panel side.
Public address and voice alarm
A public address system carries speech and music to chosen zones. A voice alarm system adds supervised equipment, standby power and a link to the fire panel, so recorded messages play on alarm.
Many buildings use one network for both. Paging and announcements run all day, and the same speakers carry the evacuation message in an emergency.
Zones, speakers and amplifiers
The building is split into zones such as floors, wings, stairs and car parks. Each zone has its own volume and can be called on its own or with all others.
Speakers are chosen by room. Ceiling speakers suit offices and corridors, horn speakers suit yards and plant, and column speakers suit halls with echo. We place them so speech stays clear and even.
Standards for voice alarm
Voice alarm equipment is judged against EN 54 parts, including EN 54-16 for control equipment and EN 54-24 for loudspeakers. We use equipment that follows these parts where a design calls for voice alarm.
Bosch supplies the control, amplifier and speaker lines we use. Exact models follow the current range, and we confirm them on the quote.
Who we design for
Builders, architects and MEP consultants can send us the ceiling plan and the specification, and we return a zoned layout with a price. Corporates use paging across floors and campuses. Hospital owners need quiet-ward zones and clear speech for staff calls. Industries need loud, weather-resistant units in yards and workshops. Defence establishments, including Indian Navy and Army sites, can ask for a plan and quote, subject to their security and vendor-registration rules.
Linking to the fire alarm
On alarm the panel can start a pre-recorded message in the affected zones first, then the rest of the building. Messages can tell people to avoid lifts and use the nearest stairs.
This works well with an addressable fire alarm, where the panel knows the exact floor. We test the link line by line with the fire alarm team.
Servicing and testing
A speaker line that fails quietly is found at the worst time. Each service visit plays a test message in every zone, checks amplifiers and standby power, and lists faults in writing.
We service each public address system in Hyderabad on a written schedule, and our fire safety AMC can include it in the same visit as the fire alarm.
Public address systems across Hyderabad
Offices and campuses in Gachibowli, Hitech City and the Financial District use paging across floors and food courts. Hospitals in Banjara Hills and Secunderabad need quiet-ward zones and staff calls.
Malls in Kukatpally and Miyapur need clear speech over background noise. The Telangana State Disaster Response & Fire Services Department inspects the fire side of the building, including the voice alarm link. Our Gachibowli team designs and services each system, and the Hyderabad office page lists our other work. See our public address system in Visakhapatnam page for our coastal work.

Standards and approvals
We design to NBC 2016 Part 4 and IS 2189 for the fire alarm link, using equipment that follows EN 54 where voice alarm is required. The fire department decides what each building needs, and Essatech does not issue or promise approval. This applies to every public address system in Hyderabad we design. Our public address system service page lists the basics.
