Siemens SL24XSPS-FW is an SL2 Series Type 4X weatherproof speaker-strobe in white with a clear lens and FIRE marking. SL2 weatherproof models are for indoor or outdoor use and can be mounted on a wall or ceiling, using the SL24XBB surface back box.
The speaker uses a high efficiency driver across 400 to 4000 Hz, and the strobe meets the NFPA 72 (2016) 20 millisecond light pulse requirement. SL2 appliances are compatible with panels and accessories that support Siemens ST strobe based products, and can share a notification zone and field of view with them. Strobes synchronize with a panel using Siemens sync protocol, a DSC sync module or a Siemens power supply.
