Hikvision HF-SS2-R Wireless Sounder Strobe is a wireless fire alarm notification device designed to provide both audible and visual warnings when a connected wireless fire alarm system enters an alarm condition. The HF-SS2-R uses 433MHz LoRa wireless communication and combines a sounder with a red LED strobe in one compact device.

The Hikvision HF-SS2-R is designed for integration with compatible Hikvision wireless fire alarm equipment through a gateway. Its dual alarm output provides a sound level of 75–100dB at 3 metres together with a visual flashing indication, helping occupants recognize a fire alarm condition through both audible and visual signals.

Wireless Sounder and Strobe

The HF-SS2-R Wireless Sounder Strobe combines two fire alarm notification functions in a single device. The built-in sounder generates an audible alarm while the red LED strobe provides a visual warning.

This combination can help provide clearer alarm notification in areas where occupants may not immediately hear an audible alarm. The visual strobe provides an additional indication that the wireless fire alarm system has entered an alarm condition.

433MHz LoRa Wireless Communication

The Hikvision HF-SS2-R uses 433MHz LoRa wireless communication. This allows the sounder strobe to communicate with compatible wireless fire alarm system equipment without requiring conventional signal cabling between the device and gateway.

LoRa wireless communication can provide installation flexibility in existing buildings, renovated premises and locations where installing additional fire alarm wiring may be difficult. The available system information identifies the HF-SS2-R as a 433MHz LoRa sounder strobe within Hikvision’s wireless fire alarm range. :contentReference[oaicite:0]{index=0}

75–100dB Audible Alarm

The Hikvision Wireless Fire Alarm Sounder provides an adjustable alarm sound output of approximately 75–100dB at 3 metres. The audible warning is designed to alert occupants when an alarm signal is received from the connected wireless fire alarm system.

The actual sound level experienced within a building depends on room size, building materials, background noise and device positioning. The number and placement of notification devices should therefore be determined during the fire alarm system design.

Red LED Visual Strobe

The HF-SS2-R Fire Alarm Strobe includes a red LED visual warning that flashes when the device enters an alarm condition. The visual indication works alongside the audible alarm to provide dual-mode notification.

Using sound and light together can make an alarm condition easier to recognize in suitable indoor environments, particularly where background noise or other conditions may affect the effectiveness of an audible alarm alone.

Multiple Status Indicators

The Hikvision HF-SS2-R Wireless Sounder Strobe provides multiple status indications. The available product specifications identify red for alarm, green for communication/normal status and yellow for fault indication. :contentReference[oaicite:1]{index=1}

These indicators provide useful local information about the device’s current condition and can assist maintenance personnel when checking the wireless fire alarm installation.

Wireless Fire Alarm System Integration

The Hikvision HF-SS2-R is designed to operate as part of a compatible Hikvision wireless fire alarm system. A wireless gateway can provide communication between the sounder strobe and the wider fire alarm network.

The HF-SS2-R can therefore be combined with compatible wireless smoke detectors, heat detectors, manual call points and other fire alarm components according to the requirements of the installation.

Remote Mute Function

The Hikvision Wireless Sounder Strobe supports remote mute functionality according to available product information. This allows the sounder to be silenced through the appropriate wireless fire alarm system controls when the system configuration and operating procedure permit it. :contentReference[oaicite:2]{index=2}

Silencing an alarm should only be performed by authorized personnel following the appropriate fire alarm procedure. A silenced sounder does not mean that the underlying fire alarm condition has been resolved.

Battery-Backed Operation

The HF-SS2-R Sounder Strobe is designed with battery-backed operation. Available product information specifies a lithium CR17450 battery with a 2400mAh capacity and 3V DC rating for the HF-SS2-R configuration. :contentReference[oaicite:3]{index=3}

The available specification also identifies up to three months of sleep/standby operation and up to 60 minutes of alarm operation under the stated conditions. Actual battery performance depends on the operating environment and alarm activity.

DC Backup Input

The Hikvision HF-SS2-R Wireless Sounder Strobe specification identifies a DC backup input. This provides flexibility for suitable installations where an additional power connection is included as part of the system design. :contentReference[oaicite:4]{index=4}

The exact power configuration should be confirmed against the product version supplied and its installation documentation before installation.

Flexible Wireless Installation

A 433MHz Wireless Sounder Strobe can provide greater installation flexibility than a conventional wired notification device. Since communication with the compatible gateway is wireless, the device can be positioned in suitable locations without running a dedicated signal cable back to the control equipment.

The wireless signal should be assessed during system installation because walls, floors, reinforced structures and other environmental factors can influence radio communication.

Wall or Surface Mounting

The Hikvision HF-SS2-R is designed for wall or surface mounting. Its compact ABS housing provides a practical enclosure for suitable indoor fire alarm installations.

The sounder strobe should be positioned according to the fire alarm system design so that both audible and visual notification can be provided effectively within the protected area.

Operating Environment

The HF-SS2-R Wireless Fire Alarm Siren is specified for an operating temperature range of -10°C to +55°C. Available product information also identifies an operating humidity of up to 95% relative humidity. :contentReference[oaicite:5]{index=5}

The device should be installed in an environment that remains within the manufacturer’s specified operating conditions and is appropriate for the intended fire alarm application.

Suitable Applications

The Hikvision HF-SS2-R Wireless Sounder Strobe can be considered for suitable indoor wireless fire alarm installations, including:

• Offices
• Commercial buildings
• Retail premises
• Hotels
• Warehouses
• Industrial facilities
• Educational buildings
• Residential and multi-unit properties
• Other suitable indoor environments

The final number and positioning of sounder strobes should be determined according to the building layout, required alarm coverage, background noise and applicable fire safety requirements.

Audible and Visual Fire Alarm Notification

The HF-SS2-R Fire Alarm Siren is a notification device rather than a detection device. It does not replace smoke detectors, heat detectors or manual call points. Instead, it receives an alarm signal from the wireless fire alarm system and communicates that condition to occupants through sound and light.

This makes the device an important notification component in an appropriately designed wireless fire alarm system, helping ensure that an alarm condition can be communicated throughout the protected areas.

Professional Wireless Fire Safety Solution

The Hikvision HF-SS2-R Wireless Sounder Strobe provides a practical combination of wireless communication, audible alarm and visual strobe notification. Its 433MHz LoRa connection allows it to form part of a compatible wireless fire alarm network.

The device’s 75–100dB alarm output, red LED strobe, status indicators, remote mute capability and battery-backed design provide useful features for professional fire alarm installations where wireless notification is required.
