Do some fire alarms squirt ink when pulled?

I am a great person to answer this question because I own my own fire alarm system (I put it together myself). The reason some fire alarms (depending how sophisticated and advanced the alarm system is) squirt ink is due to the fact that, say for example, some decides to pull the fire alarm at a school, it will leave a dye on your fingers you that you can't see, but the authorities can. They may arrest you for calling in a false alarm, and wasting the fire department's time.

It really does not "squirt" the ink. As it simply just sits on the handle of the fire alarm.

Basically how it works is they put a little vegetable based dye on the pull station handle and when the person who pulled it pulls it they will get the dye on their hands. The trick is when they attempt to wash it off of their hands , it only spreads and gets worse! This way police or whoever can easily identify the culprit because of their unusually blue colored hands. And it stays on for 48 hours!
