Help Pets and PASS scba alarm after ctb

[Nocturna666]

So the way that I plan to ctb is using the nitrogen method via a nitrogen gas tank connected to a scba mask that has a PASS alarm Preinstalled within the regulator. once the pressure drops at a certain degree it creates the alert and this is normally all fine, but I have a pet inside the house that I don't want to expose for several hours to continuous beeping from the alarm and live in a studio type of layout alone but luckily, there's people not far away that can easily come and WILL check up on him (and my then dead body) whenever the automated message sends. so my question is there any way to cover up the alarm or somehow disable it? It's a Scott e z flo regulator.
