The Siemens SET-CS17-W-WP-ALERT Weatherproof Speaker Strobe is an audible/visible mass-notification appliance designed for emergency voice communication in indoor or outdoor environments. The model is UL-listed within Siemens’ SET notification family and uses a white housing with ALERT identification.
Siemens SET-series speaker strobes combine a high-efficiency emergency speaker with synchronized visual notification. They are designed for voice messages, emergency tones, and visual signaling in mass-notification and life-safety systems.

Weatherproof Operation
The WP designation identifies the appliance as a weatherproof configuration. Siemens’ SET family includes dedicated weatherproof notification appliances for installations requiring environmental protection.
Siemens also provides a WPS-KIT for applicable weatherproof SET appliances. The kit includes hardware, plugs, and a gasket used with the appropriate mounting arrangement.
Emergency Voice Speaker
The speaker is designed for clear emergency voice reproduction over a published frequency range of:
400 Hz to 4,000 Hz.
It can reproduce emergency functions such as evacuation messages, live paging, alert instructions, and system-generated tones.
The speaker uses a sealed-back construction intended to provide additional protection while supporting clear audible output.
25V / 70V Speaker Operation
Siemens SET-series speaker strobes support:
25 VRMS
and
70 VRMS
speaker systems.
This dual-voltage capability allows the appliance to integrate with common emergency voice and mass-notification amplifier systems.
Selectable Speaker Wattage
The SET speaker platform provides field-selectable power taps from:
⅛ W
through
8 W.
Published speaker output increases from approximately 75 dBA at ⅛ W to 93 dBA at 8 W, measured at 10 feet under the manufacturer’s specified conditions.
This wide adjustment range allows the appliance to be configured for different ambient noise levels and voice-coverage requirements.
ALERT Configuration
The exact model SET-CS17-W-WP-ALERT is included in Siemens’ UL listing for SET notification appliances.
Its model designation identifies key configuration characteristics:
W: White
WP: Weatherproof
ALERT: Emergency/mass-notification marking
This differentiates the appliance from conventional FIRE-marked notification devices and makes it suitable for broader emergency communication applications.
Strobe Synchronization
SET-series speaker strobes support synchronized visual notification when connected to a notification appliance circuit using the Siemens synchronization protocol.
Siemens identifies compatible synchronization sources including applicable addressable fire alarm panels and PAD-series NAC extenders with built-in synchronization capability.
Synchronization coordinates multiple strobes so their flashes occur together rather than independently.
