Catch when satchel charge explodes

[Bellicosity 10]

I get how to catch when someone places it but how do you catch when it explodes?

I'd like the alarm to go off if it explodes, so if there is code to catch if ANYTHING explodes that'll probably work too

Can you attach a fired eventhandler to the satchel? If not, maybe just check if it's still alive?

I tried this on a fired eventhandler but it also fires if they pick up the satchel

_unit = _this select 0;
_weapon = _this select 1;
_muzzle = _this select 2;
_mode = _this select 3;
_ammo = _this select 4;

_shot = nearestObject [_unit, _ammo];
sleep 0.005;

waitUntil { !alive _shot };

hint "Boom?";
