Good morning,

I have recently moved into a new home (3months ago) where a pyronix enforce v10 house alarm system was already installed and have had no issues with up until a week ago.

Last week we were woken in the middle of the night to the house alarm blaring out, inside alarm not the external bell, upon going downstairs to turn it off it says Siren tamper, I silenced this and put it down to a power cut we just had. For the last two nights it is blaring out every 30mins, typically always at night, having looked at numerous threads and speaking to other people who have had this issue, could this be the batteries all need replacing in the sensors?

P.S I have no engineer codes, only a 4 digit code to set and unset the alarm. I have tried putting the default and numerous other default engineer codes I can find but nothing seems to work. The seller who I bought the house from does not know of any other codes other than the 4digit set and unset code. Is there a way to manually reset the whole alarm by removing the panel battery and factory reset the system?

Much appreciate any and all help.
 
The system was set up by the previous owners father, im assuming he changed the codes when he set it up, found the codes on the back of a manuel i dug out.
 
You’re going to have to see what battery pack is in the siren , more than likely it’s the two flat orange packs if it’s a version 10 …I tend to fit a psu in the loft and inject 12dc into the bellbox as the battery packs around £20 ( never had to change any with the psu fitted )
 
Appreciate this. I have attached the image of the exact system I have, although the image is from google its the exact same company etc.

Update on last night with engineer codes: I ran battery status test and all came back 'good' would this be wise to assume it is the multi switch? Also after having run these tests, the alarm did not go off last night, is it possible this has wiped any faults caused by the power cut?

Thank you

I would….. A replace the tamper switch
And ………B check the voltage of the two ( possibly) battery packs if below 3.0v dc they are on the way out …
