I just got back into Minecraft after a long long time and I started working on an adventure map. A comparator will signal in the same fashion as it does for other non-inventory non-selector blocks; when the command block activates, it will be detectable by the comparator and will only produce a signal strength of redstone equal to the number of successful activations. Alternatively you can save on comparators and use a chain of comparator, solid block, redstone dust and a solid block again. /teleport @p 8210.
