IS28VCL - ATEX & IEC Ex Banshee Intrinsically Low frequency Safe Sounder Vimpex
The IS28 Banshee is an intrinsically safe sounder for use in hazardous areas. It is available with four tones: buzz, fast sweep, slow sweep and continuous. The low frequency model has the sound output centred on 900Hz to satisfy installations that demand a low frequency sounder. The IS28 has been ITS approved to ATEX and is suitable for use in all zones (0, 1 and 2). The IS28 has also been approved to IEC Ex by Testsafe for mining applications. The product should only be connected to the fire alarm system via an approved galvanic isolator or zener barrier.
