I am Pete, and I'll be happy to assist with your question today.
Do you have the MCS-700 wireless siren?
If so, open it up and hold the ‘SLF TST’ button for three seconds.
A low-level sound should be emitted and the strobe should flash.
Let me know if the self test is successful?
Ok, I think in that case it may be faulty - could you get it exchanged for another siren?
Ok, let me check if the other techs have any idea on this problem...
