Hi,
I flew a defense safety siren/screamer yesterday to aid in locating the rocket. It was attached to the harness and devised in a way that once the harness went taught, the pin would be pulled activating the siren for all to hear. The one I am using can be seen in the link below:
Link to siren
I ground tested this arrangement twice and it worked perfectly both times, deploying the siren perfectly.
However, the first flight did not go to plan.
The siren was deployed and was on when I came up to the rocket, although the sound emitting from it was not the usually loud and obnoxious alarm, but a faint electronic gurgling sound, that could only be heard once almost on top of it.
I inserted the pin and activated it again, same thing - faint gurgling. After a few more times of this, the alarm suddenly came back to life, working as advertised.
I haven't been able to replicate the weird behavior since.
I'm wondering if anyone else has experienced this? How are you protecting the alarm? In my arrangement, the alarm is within fairly close proximity of the ejection charge. I wonder if the charge messed with the piezo buzzers some how? Appreciate everyone's insight!
