The Gentex WSSPK24-15/75WR Outdoor Speaker Strobe provides dependable audible and visual notification for compatible fire alarm and emergency communication systems. It combines a high-quality speaker with a fixed 15/75-candela xenon strobe. In addition, its outdoor-rated construction supports reliable signaling in demanding environments.
Outdoor Fire Alarm Notification
The Gentex WSSPK24-15/75WR belongs to the WSSPK Series of outdoor notification appliances. It features a red faceplate with FIRE lettering and a clear strobe lens.
The speaker delivers emergency voice messages and audible warning signals. Meanwhile, the strobe provides a flashing visual warning during an alarm condition.
As a result, the appliance combines two notification functions in one wall-mounted assembly. This design can simplify installation when both audible and visual signaling are necessary.
Fixed 15/75-Candela Strobe
The integrated xenon strobe operates at a nominal 24 VDC. It provides a fixed 15/75-candela configuration rather than field-selectable candela settings.
The strobe flashes approximately once per second during operation. Moreover, compatible Gentex synchronization equipment can coordinate multiple visual notification appliances.
Therefore, installers can integrate the strobe into supported synchronized notification systems.
Selectable Speaker Voltage
The speaker supports both 25 VRMS and 70.7 VRMS audio operation. Installers can select the appropriate voltage according to the compatible emergency communication system.
In addition, the speaker offers six field-selectable power taps. These settings provide flexibility for different sound output requirements.
Available power taps include 1/8W, 1/4W, 1/2W, 1W, 2W, and 4W.
Higher wattage settings generally increase sound output. However, they also increase the load on the connected audio amplifier.

Outdoor Weather-Resistant Design
The Gentex WSSPK24-15/75WR includes a GBLP outdoor-listed back box. This enclosure helps protect the appliance from weather-related conditions.
The GBLP back box provides IP54 protection when installed according to the applicable requirements. Therefore, the assembly can support suitable outdoor fire alarm applications.
Furthermore, the tamper-resistant grille helps protect the speaker during normal operation.
Audible Performance
The speaker provides a frequency response from approximately 400 to 4000 Hz.
At the 4W setting, the manufacturer specifies an output of approximately 87.9 dBA at 10 feet. Actual sound output depends on the selected power tap, speaker voltage, and installation conditions.
Consequently, technicians should verify audible coverage according to the approved emergency communication design.
Typical Fire Alarm Applications
This outdoor speaker strobe supports commercial and industrial emergency notification systems.
For example, compatible installations may include warehouses, manufacturing facilities, parking structures, transportation areas, loading docks, and exterior building locations.
The speaker can deliver evacuation instructions through compatible voice communication equipment. At the same time, the strobe provides visual notification during an emergency.
Installation and Compatibility
Before installation, verify the speaker voltage, wattage setting, strobe power supply, and notification circuit capacity.
Also, confirm the required synchronization method and GBLP back box installation requirements.
Qualified fire alarm professionals should install and test the appliance. In addition, technicians should follow Gentex instructions and applicable fire alarm codes.
Overall, this Gentex outdoor speaker strobe provides a practical solution for combined audible and visual notification. Its fixed 15/75-candela strobe, selectable speaker settings, red FIRE faceplate, and weather-resistant mounting enclosure make it suitable for professional emergency communication applications.
