Ansul Restaurant Electric Detection (RED) Technology

ANSUL® Restaurant Electric Detection (RED) Technology is an electric, fully supervised and monitored technology designed to work with ANSUL R-102 and PIRANHA Fire Suppression Systems.

ANSUL® RED Technology provides intelligent and reliable multi-zone fire protection for complex, commercial kitchens. It’s smart enough to cover all your cooking stations, but simple enough to make it easy to manage.

The technology delivers next-generation commercial kitchen fire protection with industry-leading centralized monitoring and real-time status of up to 16 hazard zones.

Combining linear detection with electric actuation, ANSUL® RED technology simplifies fire protection for the food-service industry by monitoring individual hazard zones that discharge only when and where they are needed.

New ANSUL® RED technology integrates with ANSUL® R-102 or PIRANHA suppression systems for complete, scalable, UL-compliant protection from detection to suppression.

ANSUL® RED technology is expandable for added hazard zones including pollution control units (PCUs). The system features up to eight controllers, which can monitor two hazard zones each and all connect to one display module for centralized monitoring. RED Technology provides the flexibility to protect a full spectrum of appliances used in today’s demanding kitchens by offering a wide range of detection options that tie into a 4,000-event history log.

ANSUL RED technology meets NFPA 96 – Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations and NFPA 17A – Standard for Wet Chemical Extinguishing Systems. It is fully listed with Underwriters Laboratories (UL) when combined with globally relied upon ANSUL R-102 or PIRANHA restaurant fire suppression systems.


ANSUL® RED technology provides confidence and safety in high-volume cooking environments by helping to minimize the potential for grease build-up and by simplifying maintenance. It offers a cleaning mode, which allows kitchen staff to disengage individual hoods while keeping other hoods in operation. The system automatically resets itself in the event the system is not re-engaged and offers confirmation when active.

System integrity is enhanced through password protection for Authorized ANSUL Distributor access while service and maintenance notifications provide 24/7 troubleshooting to keep kitchens running efficiently.

ANSUL® RED Technology integrates with existing ANSUL® R-102 or PIRANHA Suppression Systems for complete, scalable, UL compliant protection from detection to suppression.

Superior versatility

The expandable system accommodates growth and allows for the monitoring of up to 16 zones

Configuration tool makes system installation and setup clear

Easy integration with existing ANSUL® fire protection systems with no change to the basic fire suppression system

Multiple temperature ratings in a single hazard zone adapt to the needs of a wide variety of appliances


ANSUL® RED technology is desirable for high-volume cooking environments in a wide range of applications:

Smarter protection

Centrally monitored fire hazard zones reduce downtime and cleanup by discharging ANSUL® Fire Suppression Systems individually, only where needed rather than entire kitchen

A 4,000+ event history log with real-time date stamps provides a comprehensive record

Single display unit centralizes monitoring and simplifies control of up to 8 controllers

Hood cleaning mode allows kitchen staff to disengage one hood while keeping other hoods in operation and a failsafe timer automatically resets the system if the hood is not manually reengaged

Password protection for Authorized ANSUL® Distributor access maintains system integrity

The system helps minimize the potential for grease buildup and simplifies maintenance

Greater peace of mind

When combined with ANSUL® R-102 and PIRANHA systems ANSUL® RED Technology holds a complete UL and ULC Listing

Service and maintenance notifications and around-the-clock troubleshooting simplify maintenance schedules

ANSUL® RED Technology meets NFPA 96 and 17A requirements

Advanced features and targeted suppression simplify and reduce maintenance

Real-time monitoring of multiple zones provides 24/7 safety
