Are Maglock Egress Devices Required To Be Hard Wired?

On access-controlled mag lock doors where we provide both a REX button and a REX Motion sensor, we usually hard-wire the lock control voltage through both devices and then use the second set on contacts in the REX motion sensor as an input to the access controller (which is programmed to also release the mag lock when actuated).

My question is this >>> I am seeing others only hard-wiring one of the egress devices (usually the REX button on the wall) and only using the motion sensor as an input to the access control system (not hard wired to the lock voltage). Does this meet Life Safety Code requirements?

Thanks
