THIS IS BIG! ANSUL R-102 Overlapping Appliance Protection has EXPANDED. New distances between nozzles and new piping rules are just two of the many enhancements now offered. When flexibility and simplicity are the most important features for a kitchen design, ANSUL Overlapping Appliance Protection provides a virtual fire-free zone where appliances of various types and sizes are protected – even if they are replaced or rearranged under the hood.

The expanded R-102 Overlapping Appliance Protection option has been tested and is listed by Underwriters Laboratories Inc. - both UL and ULC.

New Features and Benefits

R-102 Overlapping Appliance Protection brings many features which, together, offer you and your customers simplified design, lower installation costs, and future flexibility…

• Nozzle Spacing – Expanded from 12 in. (305 mm) to 25.5 in (647 mm). Nozzles are spaced a maximum of 11.5 in. (292 mm) from each end of the hazard, and then spaced a maximum of 25.5 in. on center until the complete hazard is covered as illustrated below. This new spacing allows for standard 24 in. (609 mm) pipe nipples to be used between nozzle drops, minimizing the need to cut and thread pipe in the field.
• New Simplified Piping Rules – R-102 Overlapping Protection now utilizes a total length of pipe and number of elbows for each system which allows unlimited flexibility and ease of installation. When using Overlapping Protection, you no longer need to worry about branch lines, supply lines or equivalent length. See the attached Nozzle Coverage/Overlapping Summary Sheet for specifics.
• Range Protection – Protection for ranges is now 30 in. (762 mm) deep x unlimited length.
• Hardware Reduced – With the expanded distance from nozzle to nozzle; the number of drops, nozzles and accessory components are drastically reduced – making systems more competitive.
• Appliances may be interchanged freely or upgraded without changing nozzle placement as long as appliances stay within the zone of protection.
• High Proximity Nozzle Placement – Nozzles are installed 40 in. to 45 in. (1016 – 1143 mm) above the cooking surface.
• Existing Nozzles are used for Overlapping Protection. Use the 245 nozzle on each end of zone and the 260 nozzle for everything in between. All nozzles are simply aimed at the center of the zone.
• Detection Placement – Detectors may be conveniently spaced every 24 in. (609 mm) under the hood. The best approach is to start at the duct placing one detector in the duct and then every 24 in. thereafter in each direction.
• Standard R-102 Components are used for Overlapping Appliance Option. No additional components are needed for inventory.
