Problem with Trigger_hurt, and Timers, and reset

Hey guys! Long time no see! I'll cut straight to the point. I am creating a HL deathmatch map and in this map i have a triggered nuke (i am trying to create one like y2_nuke if anyone remembers that map). Here is what i have so far: 1 Button that triggers multiple Multi_managers

Each multi_manager is set to do a different task in the explosion sequence (eg. the multi_manager nukestage1 triggers a message and a warrning sirren as soon as the button is pressed. the m_m nukestage2 with a delay of 20 seconds sets off the sound of a jet flying over, and nukestage3 sets off the trigger_hurt and the env_fade at about 25 seconds)

Everything in the sequence works just fine, but i cant figure out how to get everything to reset after the env_fade is done. My second problem is that i want a TIMED delay on a cover for the button so that it takes a couple of minutes for the nuke to "warm up" after the level initaly starts.

I know this is outdated, but i can't find any good info on the nuke setup for HL1. Thanks guys!!

1. Make trigger_relays(with their state set to off) turn off the lights(if your sirrens emmit red light), env_renders will make the volumetric rotating lights(if your sirrens have them) disapear. I think the env_fade is reset anyway, and as for the trigger_hurt does it continue to hurt after you trigger it in the second time? If it doesn't make a multisource that starts off(it regurally starts like that) and make the multimanager target it instead. After the bombing is done make the multimanager target it again.(to turn it off again)

2. Make a Trigger_auto(does it work the same in MP as in SP? and tick the remove on fire flag) with the trigger state set to on that targets a multisource that is the master of that button.
