System Sensor SRHKA-F Outdoor Wall Strobe

The System Sensor SRHKA-F is a red, wall-mounted outdoor strobe designed to provide high-intensity visual emergency notification in compatible commercial fire alarm systems. The -F suffix identifies the French-marked version, making it suitable for installations requiring French fire alarm appliance labeling.

This SpectrAlert Advance notification appliance provides field-selectable high-candela output, weather-resistant construction, synchronized flashing, and plug-in installation. The standard outdoor configuration includes a plastic weatherproof back box. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Provides visual fire alarm notification
• Produces a synchronized flashing signal
• Supports outdoor and weather-exposed installation
• Provides field-selectable high-candela output
• Supports French-language appliance marking
• Operates on supervised notification appliance circuits
• Provides notification for occupants with hearing impairments

Electrical & System Information

The SRHKA-F operates on compatible regulated DC or full-wave rectified notification appliance circuits. It is designed primarily for 24-volt fire alarm applications, with operating current determined by the selected candela setting and applied circuit voltage.

The appliance supports the System Sensor synchronization protocol and is electrically compatible with selected legacy SpectrAlert equipment. The strobe flashes approximately once per second during alarm operation.
