If you are comparing the Ansul R-102 with the American Fire Control (AFC) kitchen fire suppression system for your restaurant, the short answer is this: both are wet chemical systems installed on the hood, exhaust duct and cooking appliances, but they differ in how they detect and actuate, in cylinder sizes, and in what each manufacturer’s documents state about listings. The right choice starts with your kitchen, not the brand name.
This comparison sets out what each system’s official datasheet or catalogue says, item by item, with a summary table and practical selection steps. Both systems are available in Saudi Arabia through AZEIDK kitchen fire suppression solutions, including design, supply, installation and maintenance.
Key takeaways
- Both systems discharge a wet chemical agent through fixed piping and nozzles aimed at the hood, duct and cooking appliances.
- The Ansul R-102 datasheet states it is UL Listed and meets UL 300, and is ULC Listed. The AFC catalogue states its systems are tested in accordance with UL 300 and UL 1254 requirements but gives no listing number, so check the listing for the supplied model.
- R-102 detection uses mechanical fusible links or electric thermal detectors. The AFC system uses linear heat sensing cable and a solenoid valve with battery backup.
- R-102 tanks are 5.7 L and 11.4 L. AFC cylinders run from 7.5 L to 27.5 L, each with a set number of flow points.
- There is no universal “better” system. The manufacturer’s listed design, the cooking line-up, hood length and consultant and Civil Defense requirements decide.

Why restaurants compare Ansul and AFC
A cooking oil fire in a fryer or on a griddle cannot be put out with water, and a dry powder extinguisher is not enough. Commercial kitchens therefore rely on a fixed system inside the hood that detects the fire, discharges a wet chemical agent that cools the oil and forms a foam layer on its surface, and then shuts off gas or power to the cooking appliances.
In Saudi Arabia, the Saudi Fire Protection Code SBC 801 applies as part of the Saudi Building Code, and the General Directorate of Civil Defense reviews building safety requirements. NFPA 17A (wet chemical extinguishing systems) and NFPA 96 (commercial cooking ventilation) are technical references the designer adopts or the project specification calls up. For more on these standards, see our article on UL 300, NFPA 17A and NFPA 96.
Two names come up often in quotations and specifications: the Ansul R-102 from Johnson Controls, and the American Fire Control kitchen system. AZEIDK offers both, so the real question is not which is stronger, but which suits this kitchen and this specification.
Ansul R-102: what the datasheet says
Ansul is a Johnson Controls brand, and R-102 is its restaurant fire suppression system. From the official datasheet (Form No. F-2004004-09):
- Agent: wet chemical, a mixture of organic salts, pH 7.7 to 8.7.
- Listings: “UL Listed”, meeting UL 300, and “ULC Listed” to ULC/ORD-C1254.6. On 17 April 2024 Johnson Controls announced that R-102 had been certified to EN 17446 by BSI.
- Detection and actuation: temperature-rated fusible links, or electric thermal detectors set at the factory. The AUTOMAN regulated release fires a gas cartridge (CO2 or nitrogen) that drives agent from the tank.
- Manual actuation: remote pull station.
- Tanks: 1.5 gal (5.7 L) and 3.0 gal (11.4 L), 110 psi working pressure. One regulated release supplies one, two or three tanks depending on the cartridge, and a regulated actuator is added for larger systems.
- Piping: Schedule 40 black iron, chrome-plated or stainless steel.
- Installation temperature range: 0 to 54 °C.
The official Ansul website describes two nozzle layouts: appliance-specific, with nozzles aimed at the hazard area of each appliance, and overlapping, which overlaps nozzles to give continuous coverage over a group of appliances. For the brand in Saudi Arabia, see ANSUL in Saudi Arabia, and the product page: Ansul R-102 restaurant fire suppression system.
American Fire Control kitchen system: what the catalogue says
The product catalogue (Form No. AFC-3292), published on AZEIDK’s product page, describes a wet chemical system with a different configuration:
- Agent: wet chemical. The catalogue does not give its composition; check the datasheet or the agent’s safety data sheet (SDS).
- Testing: systems are tested in accordance with UL 300 and UL 1254 requirements, including appliance overlap and nozzle offset tests. No listing number is given.
- Detection and actuation: linear heat sensing cable rated 110 to 185 °C with an automatic actuation valve, a solenoid valve for automatic or manual operation, and integrated battery backup.
- Components: manual pull station, hooter, fire indication panel, sensing cable, nozzles, discharge piping and a pressurised stainless steel container.
- Cylinders and flow points: 7.5 L (3), 12.5 L (5), 17.5 L (7), 22.5 L (9) and 27.5 L (11).
- Energy shut-off: activation shuts off electrical and gas supplies. The gas valve type is not specified.
- Option: a water-assist provision that can be activated about five minutes after discharge.
AZEIDK’s product page adds that nozzle quantity and flow points are selected according to hood size. For the brand, see American Fire Control (AFC) in Saudi Arabia, and the product page: American Fire Control kitchen fire suppression system.

Practical differences for restaurant owners
Mechanical links or linear heat cable?
A fusible link is a metal element that separates at a set temperature and trips the R-102 mechanical release. Links are replaced periodically because grease builds up on them. The AFC linear heat cable runs along the hazard area and signals when it reaches its operating temperature, working with a solenoid valve, indication panel and backup battery. Each method has its own inspection items, so ask for the maintenance scope of each before you sign.
Hood length and number of appliances
R-102 is built from small tanks (5.7 or 11.4 L) combined to suit the number of nozzles. The AFC system uses one cylinder sized for the flow points needed, up to 11 on the 27.5 L cylinder. In both cases, the manufacturer’s listed design and calculation set the nozzle count and positions, not a visual estimate.
Changing the cooking line-up
If the kitchen often rearranges its appliances, ask about overlapping coverage. Ansul states it explicitly on its website. The AFC catalogue lists appliance overlap testing among its tests; confirm the permitted coverage method in its design manual.
Gas shut-off and alarm interface
NFPA 96 requires that, when the system operates, all sources of fuel and electrical power that produce heat to the appliances it protects shut off automatically. The R-102 datasheet confirms compatibility with mechanical and electric gas valves, and the AFC catalogue states that gas and power are shut off. Either way, the quotation should name the gas valve type and size, who supplies it, and how the system connects to the building fire alarm panel.
What consultants and Civil Defense look for in the submittal
Whichever system you choose, the technical submittal usually needs:
- The datasheet and design and installation manual for the supplied model, not just a general catalogue.
- Proof of UL listing for that model, checked in UL Product iQ.
- A hood drawing showing appliances, dimensions, and nozzle and detector positions.
- The calculation of nozzles and cylinder size or number of tanks.
- Gas valve, power shut-off and fire alarm interface details.
- The maintenance and post-discharge recharge programme.
AZEIDK can help you prepare these documents and follow them up with the consultant and Civil Defense.
Maintenance and recharge after discharge
A kitchen suppression system can sit for months without operating while grease builds up on detectors and nozzles. The R-102 datasheet requires inspection, maintenance and recharge per the manufacturer’s listed manual. For the AFC system, ask the supplier for the operation and maintenance manual covering the heat cable, valve and battery checks. After any discharge, the system is recharged and consumables replaced before the kitchen restarts.
How to choose between Ansul and AFC for your kitchen
- Start with the specification: if it names a brand or a specific listing, the choice is made; otherwise get the consultant’s written acceptance of any alternative.
- Collect kitchen data: hood length, number of ducts, and a list of cooking appliances with dimensions and fuel type.
- Verify the listing: ask for the UL listing number of the supplied model and check it yourself.
- Compare designs, not brands: nozzle count, cylinder size or number of tanks, detection method and gas shut-off.
- Ask about service: who maintains it, and whether spare parts and recharge are available in Saudi Arabia.
- Get two quotations with the same scope: so the difference is in the system, not in missing items.
Both systems, the Ansul R-102 and the American Fire Control kitchen system, are available through AZEIDK, and a design for each can be prepared on the same kitchen so you compare them on one basis.
Frequently asked questions
What is the Ansul R-102?
It is the commercial kitchen fire suppression system from Ansul, a Johnson Controls brand. It discharges a wet chemical agent through fixed nozzles over the hood, duct and cooking appliances, and is actuated by fusible links or electric thermal detectors.
Is the American Fire Control kitchen system UL 300 listed?
The product catalogue states that systems are tested in accordance with UL 300 and UL 1254 requirements but gives no listing number. Ask for the listing number of the supplied model and check it in UL Product iQ.
Does a kitchen suppression system need electricity to work?
It depends on the system. R-102 uses fusible links and a mechanical release with a gas cartridge, and can be fitted with electric detectors. The AFC system uses a heat cable and solenoid valve with integrated battery backup, according to its catalogue.
Does a kitchen suppression system shut off the gas automatically?
Yes, this is a core part of the design. R-102 is compatible with mechanical and electric gas valves, and the AFC catalogue states gas and power are shut off on activation. Specify the valve type in the quotation.
Which is better, Ansul or AFC?
There is no single answer for every kitchen. The right system is the one that matches the project specification, covers the appliances per the manufacturer’s design, and can be serviced and recharged close to you.
How often does the system need maintenance?
Maintenance follows the manufacturer’s manual and the NFPA 17A and NFPA 96 requirements the project adopts, which in practice means a service visit at least every six months, plus a recharge after any discharge.
Are both systems available in Saudi Arabia?
Yes. The Ansul R-102 and the American Fire Control kitchen system are both available through AZEIDK, with design, supply, installation and maintenance.
Summary
The Ansul R-102 and the American Fire Control system are both wet chemical systems for hoods and cooking appliances. The real differences are in detection, cylinder configuration and what each document states about listings. Compare them on your own kitchen layout, verify the listing of the supplied model, and agree the maintenance scope before installation, not after.
