Wheelock® Series RSSP Strobe Plate
Cost-Effective, Multi-Candela Retrofit Signaling for Fire and Suppression Systems
The Wheelock® Series RSSP Multi-Candela Strobe Plate from KiddeFenwal offers a cost-effective, retrofit-ready visual signaling solution designed to integrate easily with existing audible devices such as bells, horns, multi-tones, and speakers.
Engineered for reliable performance and fast installation, these strobes mount directly to standard 4-inch backboxes for flush mounting, or to the SBL2 backbox for surface mounting. With multiple candela settings, flexible labeling, and synchronization compatibility, the RSSP Series is ideal for expanding or upgrading existing fire alarm and suppression systems.
