Product Overview

The FW2961 Horn Strobe is a combination audible/visual signaling device designed to meet modern fire alarm notification requirements. By combining a clear electronic horn with a high-intensity xenon strobe in a single unit, it provides comprehensive notification for all building occupants while minimizing installation time and complexity.

Dual Notification

Combines 85 dB horn with selectable 15/75/110 cd strobe for comprehensive alerting.

UL Listed Safety

Certified to UL1971 and UL464 standards for fire alarm signaling devices.

ADA Compliant

110 cd setting meets ADA requirements for sleeping area notification.

Dual-Mode Operation

Audible Mode: 85 dB electronic horn with Temporal Code 3 pattern

Visual Mode: Xenon strobe with clear white light output

Synchronization: Flash synchronized with horn pulses

Field Selectable: Candela setting and tone pattern

Energy Efficient: Low current draw for extended system capacity

Weather Resistant: IP54 rated for indoor/outdoor use

Combination Benefits: Using a single combination device instead of separate horn and strobe units reduces installation time by approximately 40%, decreases wiring requirements, and provides consistent spacing for both audible and visual notification. The FW2961 is ideal for modern building designs where aesthetics and installation efficiency are priorities.
