+---- Thread: Cequra 2 siren stopping working, "hanging". (/thread-1865.html)
- norrisp90 - 05-30-2010
Hi,
I have a Cequra 2 siren connected to Comfort as follows:
Comfort Cequra 2
SRN + +VE Hold off
SRN - Siren
COM -VE Hold off
Input Zone Tamper (-VE)
S12V Set
STR - Strobe
Two resistors supplied with Cequra were also needed from +VE Hold off to Siren and Strobe to prevent permanent activation. Siren and strobe are set to -VE applied/positive removed triggering SAB mode and siren reverse is not activated in settings.
The problem:
The siren works fine when tested for a day or two but then stops activating to triggered alarms. The strobe always works correctly.
If I climb up and disconnect the battery and wired supply to \"reboot\" the siren so to speak it will work correctly again for a few days.
I suspect that the Alarm2beeps siren when arming command may have something to do with it as I have never heard beeps from the siren when arming, I have tried adjusting the siren lengths as mentaioned elsewhere to no effect.
Do you have any suggustions what might be causing my siren to hang like this?
Thank you,
Paul.

When this happens again, ie siren does not sound, measure the voltage between +Hold Off and Siren terminals at the siren. It may give a clue
