The trades button operates when the time clock is on. This will allow access by pressing the trades button during the times set on the time clock.
Looks like the trade button will open the door when the time clock goes normally closed which will be the specific times you program into it. So example you program the timeclock for 9am-5pm and thats the time when the trade button will work anytime outside that it wont do anything
The lock has a hard positive. i.e its always there. The negative goes through the trade button only when its pressed. It then goes over to the timeclock. The Com, NO, NC is just a clean switch. when the times programmed in the clock are active the negative is allowed to cross from the NO terminal to the Com terminal as it comes out of the Com terminal it goes into the negative side of the lock and thus completeing the circuit and door opens
The lock is a fail safe, which means it needs power to open. 12v positive is wired direct to the lock, and neg supply is switch via th push button. the time clock open circuits the push neg supply when out of hour (or time set) and closes the circuit to allow push button to work.
I should point out that some locks require power to keep the door locked rather than applying it to open it. In that case it would be used instead of the NO but thats not what we have here so yeah as i said its not used in this case
Isnt that what all the locks do anyway? they are kept locked at all times? ( also i live not far from Inverness either
You get two types of lock Fail Safe and Fail open. A Fail Safe lock means that if you take the power away it is still in the locked position and requires power to open it. A Fail Open lock will open when you take the power away and requires power to lock it.
And where abouts from Inverness?
