Longer duration is normally a larger size battery or a parallel configuration.
You can simply join each pole wire of the system ie: positives and negatives, then put those on the correct pole of your battery configuration ( whether single or parallel ). The systems will draw what they need. My only concern would be that both systems will try charge the battery as well, not sure on the repercussions of that. And it won't help to have a large battery and trickle chargers unless you have a looking time between loadsheding. Alternatively hookup a separate charger to the battery which a higher charge rate but disconnect the alarms first I think, or some sort of protection.
i think im just going to buy a 6.4 amp psu with a bigger battery and then remove the transformers from the alarms and up the voltage from the psu to 16v and run both alarms from the bigger battery PSU

Keep the voltage the same on the PSU, won't matter if its in parallels. But if you going to remove the transformers, what's going to charge your battery? Your system will then claim its in permanent failover. Or are you going to run that psu side and still leave a little 7ah on the panels battery circuit. Basically you doing a ups then.
