Description
The AGNI-301 Manual Break Glass Call Point is a reliable and universally designed conventional manual call point used for immediate fire alarm activation in fire detection systems. Built with a 1.2 or 1.6 SWG solid sheet metal enclosure, it offers long-term durability in demanding indoor environments.
A blinking red LED confirms normal healthy operation, while a steady red LED indicates alarm activation. In an emergency, users simply break the fragile glass panel using any object or the provided nickel-plated hammer with chain, which activates the internal switch and instantly triggers the fire alarm circuit for rapid response.
After activation, the broken glass can be replaced using the standard 1.8 mm thick fragile glass panel, restoring the device for continued use.
Designed in compliance with IS 2189, EN 54-5-7, and certified by ERTL / NABL, the AGNI-301 is ideal for installation along escape routes, exits, and staircases at a recommended mounting height of 1.4 m ± 0.2 m.
Its compact size, high humidity tolerance of 95% RH, wide operating temperature range from -2°C to +87°C, and IP21C indoor protection rating make it a dependable solution for commercial, industrial, and institutional fire safety systems.
Manufactured by Agni Instruments Engineers India Private Limited, the AGNI-301 reflects precision engineering and strict safety compliance.
