System Sensor SPCWL L-Series Indoor Ceiling-Mount High-Fidelity Fire Alarm Speaker, White

Designed to support efficient installation and dependable notification, this speaker and speaker strobe features a plug-in design and protective cover that help reduce ground-fault risk and prevent wire damage. The universal mounting plate lets installers pre-wire, dress conductors, and check continuity before attaching the device.

Installation uses a 4 × 4 × 2⅛-inch back box; flush-mount applications do not require an extension ring. A temporary catch holds the device in place while the captured mounting screw is secured.

• Onboard shorting spring for wiring-continuity testing
• Seven field-selectable candela settings for ceiling units: 15, 30, 75, 95, 115, 150, and 177
• Automatic 12- or 24-volt operation at 15 and 30 candela
• Rotary switches for 25 or 70.7 Vrms speaker voltage and ¼, ½, 1, or 2-watt settings
