I’m going to ask the question - why are the alarms even necessary?
I bought my Perdix and Dive in OC Tec mode. No alarms for me as I pay attention to my computer.
However that's not to say that alarms aren't a good idea for some divers. I was on a dive and a dive buddies alarm went off for exceeding MOD as his computer was on a nitrox setting from his previous dive. He was on air but did not change his setting back to air. He was an AOW with a new computer and he thought it was my alarm going off.
We advised he skip his third planned dive of the day ( this was his second ) as he could not know if he had exceeded NDL for air being on a nitrox setting. He skipped the afternoon dive and was fine. No DCS symptoms.

Same for me I manage to shoot photo's and video and still pay attention to my Perdix. Before I take photos I check for NDL time, CNS etc.
