Agni Conventional Smoke and Heat Detectors in Bhopal

Agni makes conventional smoke, heat and multi sensor detectors for zone based fire alarm panels: QS models with two 360 degree LEDs, and low profile models with a bi-colour status LED. FPS, an Agni dealer, supplies, installs and maintains them in Bhopal and across Madhya Pradesh.

Where to use Conventional Detectors

  • Offices, hotels and hospitals
  • Rooms with soft furnishings, plastics or foam (smoke detectors)
  • Schools, shops and retail outlets
  • Kitchens (heat detectors)
  • Boiler rooms and generator rooms (heat detectors)
  • Parking areas (heat detectors)
  • Warehouses and workshops
  • Industrial areas with dust, fumes or steam (heat detectors)
  • Small and medium buildings on conventional panels

Agni Conventional Detectors models

How to choose

A conventional detector is wired with others on a zone circuit, and the panel shows which zone is in alarm rather than the exact detector. Agni's QS models are designed for open area protection and for use with most conventional fire alarm panels.

Choose smoke or heat to suit the room. Photoelectric (optical) smoke detectors suit the dense, visible smoke from slow smouldering fires in soft furnishings, plastics and foam. Heat detectors suit kitchens, boiler and generator rooms, parking areas and workshops, where dust, fumes or steam could set off a smoke detector: the QS951-2L works on a fixed temperature, and the AD318-2L is a rate of rise detector that responds to a fast climb in temperature. Multi sensor detectors combine smoke and heat sensing in one head.

The QS models have two LEDs for 360 degree indication. The LEDs flash every six seconds while the detector is powered and working, latch on in alarm and go off in a trouble condition, and the detector is reset by a brief power interruption from the panel. The QS388 models run on 9 to 33 V DC, non-polarized, so the two wires can be connected either way round. The low profile models (AD338-2HL, AD318-2L and a low profile photoelectric smoke detector) have a bi-colour status LED, low current draw and a remote alarm test feature.

The QS388-4L is a 4 wire version of the photoelectric smoke detector, for panels or interfaces that need separate power and alarm wiring. Tell us which panel you have and FPS will confirm the right detector, with a price on request.

Frequently asked questions

Smoke detector or heat detector: which do I need?
A smoke detector senses smoke and suits most rooms and escape routes. A heat detector reacts to temperature and is used where dust, fumes or steam would cause false alarms, such as kitchens, boiler rooms and generator rooms.
Fixed temperature or rate of rise: what is the difference?
A fixed temperature detector, such as the Agni QS951-2L, alarms when the air reaches its preset temperature. A rate of rise detector, such as the Agni AD318-2L, responds to a fast climb in temperature.
What do the flashing LEDs on the QS detectors mean?
The two LEDs flash every six seconds to show that the detector is powered and working. They stay lit after an alarm, and go off if the detector's sensitivity moves outside its listed limit, which signals a fault.
How is a QS detector reset after an alarm?
By a brief interruption of power, normally done by resetting the fire alarm panel. The detector that raised the alarm keeps its red LED lit, so it is easy to find.
Which approvals does Agni list for these detectors?
Agni lists EN 54 and UL for the QS models, and EN 54-7:2000 (Amendment 1) and CE for the low profile photoelectric and multi sensor models. EN 54-7 is the part of EN 54 that covers point smoke detectors.
