Access Control and Monitoring System Information
Access Control
Specification
Spec needs defining.
Description
- We want some sort of system to capture an RFID identifier, store it, associate it with a person (in such a way that we can later tie it into some sort of presently-non-existent membership database).
- It needs to interface with the door, which has some sort of radio remote control, and I guess we also need some lock/unlock buttons in the space itself to stop people manually driving the door lock (as it then becomes out of sync with itself).
- With a magnetic close sensor so that when the door is in the closed position it always relocks, but with an override (for Monday nights, for example)
- A very detailed spec for Lancester University is available for inspiration here: https://www.lancaster.ac.uk/iss/info/supplierdocs/network/LU-Access-Control-Spec-v1c.pdf
- A comparison of hackspace access control systems and membership databases can be found here:
- Paul has some ideas for a door control system.

Door Sensors
Door Closed Sensor
- The door closed sensor is a reed switch activated by a magnet.
- It's connected to a four core cable, with red and yellow wires used for the contacts.
Bolt Lock Sensor
- The lock bolt sensor is a PR12-4DN inductive sensor.
- It needs 10V-30VDC on the brown wire, ground on the blue wire and the black wire is an NPN output.
