Pyronix Siren issue

[Monty_Stranger]

Hi folks

The siren battery in my Pyronix enforcer needed changing so i bought two ES1 types form amazon and put them in following a youtube video. The siren then randomly went off intermittenly for 15 mins but then reset. This was on Sunday.

Now i get a Siren1 Wirls Suprvn Fl error which i believe means the siren is not communicting with the panel. I did read in another post that the PCB should be attached to the bell box casing with a screw - mine was not. Is this an issue? Any help appreciated as always.

The screw shouldn’t be an issue, unless you’re getting a tamper fault. Did you do a bell test following replacing the battery?
I’d be inclined to delete the bell from the system and re-learn

As above… I often find myself having to relearn the bell. Sometimes I switch the bell channel when relearning to the panel as it won’t slot back in to the bell space I’ve just deleted from.

Its the little quirks that make things interesting
