Sprinkler Annunciation Panel for Wet & Dry Fire Sprinkler Systems
AGNI-S-FLOW is a dedicated sprinkler annunciation panel built to supervise waterflow, pressure, valve and tamper switches across wet and dry fire sprinkler systems. As a conventional flow-switch monitoring and alarm control panel, it scales from a single-riser building to a 60-zone campus, activating notification circuits, zone-wise displays and remote reporting the moment a sprinkler head opens.

AGNI-SFLOW-S
Agni Veiga Series - Intellignet Addressable fire alarm control panel
A sprinkler annunciation panel is a purpose-built fire sprinkler control panel that sits apart from a building's general smoke and heat detection system. Rather than watching for combustion, it supervises the sprinkler network itself — the flow switches, pressure switches, valve supervisory switches and tamper switches fitted to each wet or dry riser.
Because a sprinkler activation is already a confirmed water discharge, this class of conventional fire alarm system is engineered around fast, unambiguous zone identification rather than multi-sensor analysis. When any input trips, the panel's job is simple: say exactly which riser or floor has activated, sound the alert, and get that information off-site to a monitoring station or the fire department as quickly as possible.
The AGNI-S-FLOW is Agni Instruments' dedicated sprinkler alarm control panel, engineered to serve as the annunciation hub for wet and dry sprinkler systems of any scale, from a single-riser small building up to a large, multi-wing campus with up to 60 supervised zones.
Conventional, not addressable.
Every zone on the AGNI-S-FLOW is a hardwired, end-of-line supervised circuit. That keeps commissioning and fault-finding straightforward on projects where per-device addressing isn't required - the panel scans all configured zones automatically every 60 seconds and reports open-circuit faults with the location on its LCD.
Latching by design.
Alarm modes are configurable as latching or non-latching, but latching is strongly recommended for sprinkler flow-switch applications - the alarm condition stays active even after the flow switch resets, until an authorized person acknowledges and resets the panel.

Frequently Asked Questions
Common questions about the Sprinkler Annunciation Panels.
A sprinkler annunciation panel is a dedicated fire sprinkler control panel that monitors the flow, pressure and valve-tamper switches on a wet or dry sprinkler system. It gives building staff and the fire department a visual and audible readout of exactly which riser or zone has activated, functioning as the primary sprinkler alarm control panel for the fire protection system rather than a general smoke and heat detection panel.
The AGNI-S-FLOW is a conventional fire alarm system. Each zone is a hardwired, end-of-line supervised circuit rather than an individually addressed device, which keeps the panel straightforward to install and maintain on projects that don't need per-device addressing. It's one of several conventional fire panels available in the 12 to 60 zone range.
Yes. The panel includes an onboard dual-line digital alarm communicator transmitter along with a built-in Ethernet port, so alarm and fault events can be reported to a remote monitoring station over telephone lines or IP, in addition to the panel's own local NAC, LCD and relay outputs.
The AGNI-S-FLOW is designed to work with flow switches from all major international manufacturers, including Potter/AMSECO, Gentex, System Sensor and Cooper Wheelock, on a Class B (Style B) supervised circuit.
The standard range covers 12, 24, 36, 48 and 60 zone models, with a maximum of 64 supervised zones. Agni Instruments also accepts custom and OEM orders configured from 1 to 64 zones, with custom enclosure dimensions, RAL colours and branding on request.
