Thats how DC smoke detectors work. Unless something has changed, only 110V smoke detectors all sound off at the same time. To get a DC smoke to auto reset is a violation of NFPA72. You can setup the zone to verify the alarm, but as far as auto reset without a panel reset breaks some NFPA72 rules I believe...

DC smokes with sounders can be made to all sound at once -- just use a reversing relay. On the rest we agree.
