The Siemens SEF-W is a white flush-mount fire alarm speaker for indoor voice notification. First, the low-profile design sits nearly flush with the wall. Then a high-efficiency driver provides strong audio at low wattage. As a result, the SEF-W blends into finished interiors.
This Siemens ‘SE’ series speaker operates on 25 or 70 VRMS circuits. In addition, field-selectable taps range from 1/8 watt to 2 watts. The speaker covers a frequency range of 400 to 4,000 Hz. Therefore, voice messages remain clear and intelligible.
Siemens SEF-W flush speaker features
The SEF-W mounts flush to a standard 4-inch square electrical box. Also, In/Out screw terminals accept #12 to #18 AWG wire for quick installation. A snap-on grille conceals the mounting screws. Furthermore, the white finish suits offices, corridors, and lobbies.
