Buffalo, NY, Friday August 3, 2018 : Stetron is pleased to announce the development of a 520Hz low frequency new miniature loudspeaker designed especially for the Fire Alarm and Protection Industry.
This driver is suitable for use in products intended to be compliant to UL217. This low profile driver has a small foot print of 57 mm and uses a Mylar cone which renders it water resistant. Despite its physical size, this 57mm x 17.5mm driver has a high output SPL of minimum 91.2dB measured at 1W/1m and a rated input power of 2W rms.
This driver is designed to meet all the performance requirements stipulated in section 84 of UL 217 . Another key feature of this small 520 Hz low frequency driver is its very low current consumption which makes it desirable for battery powered devices.
