ASP-200 BL is a siren that informs you about alarm situations by means of acoustic and optical signaling. 
It operates as part of the ABAX 2/ABAX two-way wireless system. 
The device complies with the EN 50131 Grade 2 requirements.
Acoustic signal is generated by a piezoelectric transducer (4 tones to choose from), and optical signal is provided by LED indicators. Both signals can be triggered independently.
