The FSBL-001 combines a fire alarm sounder and a strobe indicator light to warn occupants of a fire condition with both sound and light.
Mounting and placement
The FSBL-001 is designed for wall mounting in corridors, stairwells and escape routes. Mount at a minimum height of 2.0 m from the finished floor to the device, with units spaced so the red strobe flash stays synchronized (typically ≤ 45 m between units on the same circuit). The sounder reaches up to 90 dB at 1 m on 24 VDC. Per TCVN 7568-3:2015, the audible fire alarm signal must exceed the ambient noise level by at least 10 dBA (within a 65–105 dBA range), with a minimum of 75 dBA in areas where occupants may be sleeping.
