I work for the UK Fire service.
We have a problem with our lockers opening (Due to not being closed correctly) whilst on route to a call.
What we need is a way in which to monitor the lockers of the fire truck.
I have in my mind 8 reed switches (One for each locker) connected to a control box
Within the control box there is an eight way nand gate providing an output via buzzer. (When any locker is open)
in addition a set of LED's displaying which is open and which is closed.
Sounds easy?
if so you are the one for me.
Apart from the sensors I have no idea how to wire this baby up.
What resistors do i use, do i need diodes etc etc etc.
I have ordered a number of Texas 8-input NAND gate's but do not have a clue what next
PLEASE HELP!!!
