[Noisebridge-discuss] fix the downstairs door closer and add a buzzer

[Mitch Altman]

Same goes for locking the sliding doors for the fire escape that faces Mission Street (our 2nd exit) -- it has to be locked from the outside, but easily opened from the inside.

These sound like important projects! I would totally help with them. I am planning to be around for the reboot but don't have any particular projects in mind yet.
For anyone who is planning to build locks for the upstairs door please remember it is our primary exit and needs to never be lockable in a way that prevents opening from the inside. Two fire exits are required to legally raise the capacity of the space over 49 people.

here are some things you can do to solve the security problem around closing access noisebridge in the near term:



1. adjust, repair or replace the automatic door closure mechanism on the downstairs gate:

this device is for pushing the door shut, FAR ENOUGH TO LATCH, in a way that doesn't slam the door shut suddenly.  When adjusted properly, it will ensure the latch clicks every time, assuming nothing is propping the door open.




2. install a sensor to detect if the door is fully latched.  this should be a button which feels if the door is in the position of being fully closed.  it won't be able to detect if paper is wadded into the latch, or the open-handle is taped or propped into the open position, but it's something.  If done right, it will not be able to be fooled at all.




3. wire that sensor to a chime that goes off continuously in the upstairs space when the door is open.  This is the only way to monitor and deal with incidents of the door being propped open.  This sensor should also go to a computer so that scripts can notify interested parties of when exactly the door is being opened.




keep in mind that this is easier than an attempt to "lock" the upstairs door. (which is inappropriate considering the realistic need for sudden mass escape)



It is definitely easier when you remember that the elevator can access the third floor even if the door there is locked.



It is also high time that noisebridge do something about the lack of effectiveness of the gate latch.  The time to do something about it is now.



I am willing to assist others with some of these repairs.
