Trapfinding vs. the Alarm Spell

[DarkKnight27]

I'm trying to get peoples opinions on this. I've been told in the past that a rogue can use perception to find an alarm spell and disable it (like a trap) but after reading both the spell and the description of Perception and Disable Device I can't seem to find any backing for this.

Unlike every Symbol spell or Glyph of Warding or Greater Glyph of Warding which all have a note in the description that "magical traps can only be found by a rogue and have a DC of 25 + spell level to find them", the Alarm spell has no such note or description.

So my question is this: does the rogue who's searching a hallway/room even get the opportunity to notice (and then maybe disable) the alarm spell that he's just about to walk into or is it only the caster who has Detect Magic up and can then either cast Silence or Dispel Magic that can get past this spell?

The alarm spell is used as a trap trigger, not as a trap itself. As far as preventing sneaking and such, it's a pretty good spell.

There are lots of things that are pretty good against sneaking around.

Quoth Sean K Reynolds,
1) Sometimes the rules make redundant statements to prevent questions about ambiguity later.

The question is, is a redundant statement missing? Is it needed in that case? Alarm is mentioned in SO MANY TRAPS, I think stating it explicitly would be a very redundant statement.
Note: This is a lotical fallacy, a statement such as the above does not imply it's inverse.

Honestly, I'd have to ask the original author.

No?

Hmm...
Note: Magic traps such as explosive runes are hard to detect and disable. A rogue (only) can use the Search skill to find the runes and Disable Device to thwart them. The DC in each case is 25 + spell level, or 28 for explosive runes.

Based upon this (rather retarded) ruling here is how you make a trap (I can call it a trap, by definition it is one) that is not a trap and cannot be disabled as such.
Alarm (cast wherever, technically it's not a trap, remember.)
Permanent Invisibility(or paper wall)
Tiger
Alarm + concealed tiger = Trap that cannot be disabled?
(paper wall?)
Just make sure you don't let the tiger get hungry.

An alarm spell trap has a trigger (the spell), no reset, and the effect of noise. IMO it qualifies as a trap.

Though, I can see the virtue (but not the logic... that I call stupidity) of making alarm NOT able to be disabled when not a part of a more complex trap. It does make it easier for the party to keep it's things... and harder for the 'Evil DM' that is seen every so often, to steal all of the party's stuff. As such... *folds up copy of Wizards ruling, slips into backpack*. Well, I don't play rogues.

"We go hire a ranger."
"In the woods?"

emphasis: each case, indicating a general rule.

Fundamentally, I see both sides. I, as a DM, would allow alarm to be found and disabled because it is a 'trap' by the definition of the word. (And because I like consistency).
