Agni Response Indicator ABS Ceiling Mounted Concealed 502
A dual-LED concealed response indicator designed for conventional and addressable fire detectors, providing instant and clear visual alarm indication in concealed or inaccessible areas.
Part Number: AGNI-502 | Category: Response IndicatorÂ
Description
The Response Indicator Concealed – 502 from Agni Instruments Engineers India Private Limited is a remote visual alarm device developed to enhance fire detection visibility in areas where detectors are not directly visible.Â
It is commonly installed outside rooms, below false ceilings, inside air conditioning ducts, or in restricted spaces where the detector’s alarm LED cannot be easily seen. When the connected detector enters an alarm condition, the response indicator activates immediately, illuminating bright red LEDs to confirm the fire event.Â
Built with a durable FR-ABS plastic enclosure, the unit features a rugged industrial design, flush mounting, and a low-profile appearance. The dual-LED configuration ensures wide viewing angles, high brightness, ultra-low power consumption, and a long operational life.
The Response Indicator Concealed – 502 is compatible with both conventional and addressable fire alarm systems and complies with key international and Indian fire safety standards, making it suitable for commercial, industrial, and institutional installations.Â

How does the Response Indicator Operate?
1. Connection to Fire Detector
The response indicator is directly wired to a compatible conventional or addressable fire detector using a 24V DC supply.
2. Normal Monitoring State
Under normal conditions, the response indicator remains inactive while continuously monitoring the detector’s status.
3. Fire Detection
When the connected smoke or heat detector senses fire conditions, it enters alarm mode.
4. Signal Transmission
The alarm signal is instantly transmitted from the detector to the Response Indicator Concealed-502.
5. Visual Alarm Indication
The dual high-brightness LEDs illuminate red, providing a clear and immediate visual confirmation of the alarm.
6. Quick Identification & Response
The illuminated indicator allows maintenance terms and occupants to quickly identify the activated detector, reducing response time during emergencies.
Product in One LineÂ
When fire detectors are not visible, the Response indicator Concealed 502 provides a clear red LED alarm indication so users can quickly identify the activated detector and respond faster during emergencies.Â
