Agni CPWD DSR Fire Alarm Panel with PA System and Talk Back

Government and institutional tenders often ask for a fire panel as per CPWD DSR: a zonal fire panel, a public address system and a talk-back link, working as one system. The AGNI DSR conventional fire alarm system supplies all three in a single factory-built rack, so contractors get one product to submit, install and test. Agni Instruments Engineers India Pvt. Ltd. has manufactured fire detection equipment in Okhla, New Delhi since 1989, and this panel carries that years of experience.

The AGNI 6 and 10 Zone Fire Alarm Panel is a microprocessor-based conventional fire alarm control panel built as per CPWD DSR specifications, with a PA system and talk back in the same cabinet. If you are looking to CPWD DSR fire alarm panel for a government tender, a hospital, an institution or an industrial site, this system gives you detection, zone-wise public address and a talk-back link as one factory-assembled unit.

Agni Instruments Engineers India Pvt. Ltd. is a fire alarm panel manufacturer in India, Since 1989. As a DSR fire alarm system manufacturer, we build the panel, the amplifiers and the PA control desk ourselves. You deal with one supplier for the whole CPWD fire alarm system, which makes tender compliance and after-sales support simpler.

The 6 zone and 10 zone fire alarm panels share the same structure. The only differences are the number of detection zones and the amplifier wattage. The 6 zone DSR panel uses 100 W amplifiers and the 10 zone DSR panel uses 250 W amplifiers. The cabinet, talk-back, battery space and other technical parameters are identical. Zone expansion is available up to 36 zones, so the system can grow with the building.

The control panel is driven by a Cortex-M0 processor. It has a high-resolution 16x2 LCD for event information and a 12-key matrix keypad for operation. Colour LEDs show power, battery, silence, fire, open circuit, short circuit, healthy, enable and disable. Every zone can be programmed through the keypad, and each zone has its own sounder enable or disable control and programmable voltage isolation. The panel stores up to 999 events with a real-time clock. The zone-wise walk test lets engineers test smoke, heat and manual devices during commissioning without shutting down the rest of the system. Every zone also has reverse voltage protection, and the panel is protected against high mains voltage between 230V and 350V AC.

The announcement control desk has a 12-1 all-call matrix keypad with a seven-segment display, so operators can speak to selected zones or to the whole building. A handheld gooseneck microphone with an on/off switch and cardioid pickup is included, along with audio monitoring and volume controls. Two amplifiers are supplied in every panel, and a changeover switch moves between the main and the standby unit, so announcements continue if one amplifier fails.

The 23-line simplex talk-back system gives the fire control room a voice link to the field. It works as press-to-talk, half-duplex communication with TALK and LISTEN operation and the "OVER" protocol, which keeps emergency messages clear between the control room and the building. This is why many buyers choose a 10 zone fire alarm panel with talk back for hospitals, campuses and large commercial complexes.

The AGNI DSR conventional fire alarm system follows EN 54-2 for control and indicating equipment and EN 54-4 for power supply equipment. The complete system is designed to conform to IS 2189:2008. It is manufactured under an ISO 9001 quality management system, and the panel is CE conformant under the Low Voltage Directive 2014/35/EU. Together, these make it a dependable choice if you need a CPWD fire alarm panel with PA and talk back for a project that follows the DSR specification.
