Hi,
I'm interested in buying an electric bolt lock, which can also be opened by a cylinder.
This bolt connected steadily to a 12v.
It is a fail secure lock (NO).
It also as another entry for triggering a signal (to unlock the lock).
Its latch is out regularly, till a trigger occurs.
It also has a loock feedback signal (NO).
See attachment.
I would like that this bolt will function also as a switch to an electrical magnetic lock (NC).
I believe that i need to connect the maglock to the bolt feedback signal in a row.
I thought of connecting the maglock to a relay''s exit.
And use the bolt feedback signal to push an input to the relay.
Is it a correct implementation?
Thanks,
Efner

 

An interesting quest. and a bit of a puzzle as the OP(original Poster) has used different words than I use to describe almost every aspect of both the hardware and the functioning of both the hardware and the intended operation. So there may be a communications issue. And what I see is that we are given only the information that the OP has decided that we need.

What I think has been presented is that the OP is seeking to purchase is a remote door latch that is different than most in that the normally latched action is maintained by a constant electrical source to provide a power failure release function, while also providing a standard remote unlock function. This mechanism also provides a standard key/cylinder unlock, and a remote monitor contact output.

What the OP appears to be wanting to add is another function where releasing this mechanical lock will also release a separate electromagnetic door locking system. That would be normally active when the lock system is in the normal locked condition.

 

I, too, must admit to a bit of confusion. You talk about a fail-safe. Use of NO and NC to us mean an electrical switch that is Normally Open (or in its resting state) and NC which means Normally Closed (again, in a resting state). At what point is your physical lock in a resting state? Open or closed? Which do you want it to be?

If I'm guessing correctly, you want some sort of electronic signal to alert you to the state of the lock, whether locked or unlocked. Not seeing a real clear answer to these questions. Haven't yet looked at your attachments, perhaps I'll learn something there. But even then it's not easy to understand your need(s).

[edit]
OK, looked at your screen shots. They really don't tell much. So is your 12V switched or constant? I DID see that it has a 180mA draw when in standby. This begs the next question, what is the 12V source? Battery or from a power supply? If from a battery, 180mA will draw down a battery in semi-short time. It all depends on the size of the battery. I naturally think of a car battery. Ever leave a vanity light on over night in the car? Come the morning the car won't start because of a dead battery. Any smaller a battery and a vanity light, which might draw 10 watts (or 120mA) will be quickly drained. Certainly not a long term arrangement.

Now, if the battery is kept on a trickle charger, one with more than 180mA can charge and maintain a battery during standby. It can get pretty technical.

Most electrically released door locks default to locked, with only a key-cylinder available to release as an alternate. This mechanism would have the default electrically held, so that in case of a power failure it would release. A battery backup is not suitable, it is an emergency release scheme.
