Description
The Agni-302 Manual Call Point Resettable constructed from high-impact ABS plastic is a reliable and universally designed conventional fire alarm activation device built for fast emergency response and long-term performance.
Engineered for use in conventional fire detention systems, this manual call point provides immediate alarm triggering during fire emergencies. The wide-angle red LED (120°) blinks to indicate healthy operational status and remains ON when the unit is activated.Â
Designed for simplified installation and maintenance, the device features:
- Integrated on-spot reset switch (no separate key required)
- Polarity-free wire connection for easier wiring
- Low power consumption
- Dome switch thyristor latch mechanismÂ
- Integrated circuit logic
The enclosure is constructed from ABS – Acrylonitrile Butadiene Styrene high-strength plastic, ensuring durability in demanding industrial and commercial environments. A transparent polycarbonate front cave protects against tampering and false alarms.
With IP21C indoor rating and compliance with EN 54-5-7 and IS 2189 standards, the AGNI-302 is suitable for installation along escape routes, near exits, and staircase landings at the recommended height of 1.4 m ± 0.2 m above finished floor level.
How it Works

Commonly Used
- Commercial buildingsÂ
- Industrial facilitiesÂ
- Office complexesÂ
- Hospitals
- Schools
- Fire alarm system installations
Step-by-Step Manual Call Point Working Principle?
01
System Power Supply
The device is connected to a conventional fire alarm control panel operating at 24V DC (±6%). Once powered, the internal circuit begins monitoring the fire alarm zone.
02
Status Monitoring
A wide-angle red LED (120°) continuously blinks to indicate the device is healthy and in standby mode. This confirms proper wiring and operational readiness.
03
Manual Activation
In case of fire or emergency, the user presses the centre push alarm switch. The internal dome switch with thyristor latch mechanism activates immediately.
04
Alarm Signal Transmission
Upon activation: The zone circuit is triggered, The system draws up to 20 mA alarm current, The LED turns steady ON. The control panel receives the signal and activates connected alarm devices.
05
Circuit Stability
The device uses Integrated Circuit Logic with specified alarm resistance (560Ω / 1k Watts) to ensure accurate signal transmission and prevent false triggering.
06
For Reset / Silence
After the emergency is resolved: The On Spot Reset Switch is used, The device returns to standby mode, The LED resumes blinking. No additional key is required, ensuring fast and simple restoration.

FAQ
What is a manual call point in a fire alarm system?
A manual call point is a device used to manually trigger a fire alarm system during an emergency. When pressed, it sends a signal to the fire alarm control panel to activate alarms and alert occupants.
How does the Agni-302 manual call point work?
The Agni-302 operates on 24V DC (±6%). When the center push switch is pressed, it activates the zone circuit using a dome switch with thyristor latch, triggering the fire alarm system immediately.Â
Is the Agni-302 manual call point resettable?
The agni-302 features an integrated On Spot Reset Switch, allowing the device to be reset quickly without needing an additional key.
What voltage does the Agni-302 manual call point require?
The Agni-302 requires 24V DC with a tolerance of ±6%, making it compatible with conventional fire alarm control panels.
Where should a manual call point be installed?
As per IS 2189 guidelines, manual call points should be installed at 1.4 meters ± 0.2 meters above finished floor level, typically near exits, staircase landings, and escape routes.
