Door opening system V3
Basics
The system controls three separate doors:
- a black gate to the yard
- a white door at the back of the building
- the door at the 3rd floor
The gate is controlled wirelessly, either by an Arduino above spitfire, which sends the appropriate signal, or by a physical remote control, that is wired via a relay, so it can send the signal on demand.
The white door system has two separate pieces: opening the door, and unlocking the door, controlled by two separate mechanisms. The locking is done by an electro-mechanical door lock, and the opening/closing is done by an electro-magnetic door lock.
The third floor door is controlled by a simple electro-mechanical lock.
Accessing the system
The system can be accessed in the following ways:
- using fauna, which has been superseeded by Space
- by calling +359 2 462 43 56. The phone number is routed over VoIP(SIP) from support.bg to spitfire.
- using the payphone at the front gate (see below)
- using the init Lab Telegram bot
- using the initLabNotifier IRC bot at #initlab @ irc.ludost.net
Also, next to the door there are two buttons on the white box - a red and a green one. The red one locks the door, the green one unlocks it. If the door is open and you press the red button, it will lock 3 seconds after the door is closed. If the red button is pressed and then the door is closed for less than 3 seconds, the lock will not activate. But if the door is then closed for more than 3 seconds, the pending lock operation will be activated.
Using the phone
When you call the phone:
- The system checks if the source phone number is associated to an account, the account has permissions to open at least one door and a PIN has been set previously. If not, the system hangs up.
- The system picks up, and using a voice depending on the account's locale asks about their PIN code.
- It waits for a PIN code of at least 6 digits, followed by #, which is verified in the database if it's the right PIN code for this calling number.
- If the entered code is wrong, you have two more tries, if you fail, it hangs up.
- If the code entered is the right one, the voice asks which door to open, or if the user wants to lock all doors instead (currently this means lock the back door).
Using the payphone in front of the gate
- This phone is next to the front door
- You have to dial 150 to get into the system
- It'll ask you for your phone number, enter it and # after it
- Next follow the normal phone instructions (asking for a code, etc.)
Logging of actions
The system logs the door opening via twitter and IRC (#initlab on irc.ludost.net). The username of the actor is logged, or if they choose to be anonymous, the relevant message is shown instead (Someone who does not wish to be named...). Init Lab board members have access to all actions with the unmasked names, so any abuse of the system can be tracked and accounted for.
Locking/Unlocking
The door uses a Bulkey BKS300 electro-mechanical lock. It's connected though a NeoMontana NetControl 6R8A and a Bulkey BCP1 controller. There are a set of macros on the NetControl device, which can be triggered using HTTP, SNMP or MQTT. It is recommended to use the macros rather than directly controlling the relays, as this allows temporary disabling the access using NetControl's web interface. There is an option to override the sensor for closed door - use it with care! It may damage the electro-mechanical lock. It is intended to be used if the sensor malfunctions and the door needs to be locked remotely.
Opening
There is a set of scripts on spitfire that send a signal over HTTP to a NeoMontana NetControl 8R2S1A, to close a relay for 2 seconds. This relay supplies power to the electro-magnetic lock on the door, so the mechanism frees up the pin inside, and the door can be opened once. After opening and closing the door, the mechanism inside the electro-magnetic lock prevents future opening, until a power impulse is supplied again.
Settings
BCP1 jumpers: JP1 - open, JP2, JP3, JP4 - closed
6R8A settings
Settings that are not visible, are using their factory defaults.
