Hi Everyone,

I have an employee entrance that we need to wire. It has two release points, one from a reader and the other from a front desk button. I am trying to get the circuit to complete, and am having issues with getting it to work. I even bought an optional relay to add in if needed. Can you take a look at the picture and let me know where I need to put these connections? Thank you!!!!

 

Possibly like this:

 

sghioto's suggestion looks good to me.

 

Even connecting the negative on the door release to the positive on the strike? Thank you for the help!

If you are speaking of the front desk button switch then Yes.
Switches are generally not polarized.
Is there something special about this switch?

 

INDEED! SG has it quite right in post #2!!Switches seldom "have polarity." They do have terminals that can have numbers assigned for reference, or they can be marked by function, such as common, N.C. (normally closed) and N.O.(normally open.)

 

Update: I hooked it all up with a little mixed results. The Saflok RCU reader works perfectl;y, releasing the strike. The Push Button Release from the front desk is not working. I hear it clicking, but the strike is not releasing. More Info that may make a difference:

The Push Button Release from the front desk has its own individual power source not shown in the diagram, so not sure if that is important. I hear it clicking, so its trying to do something but no response from the Strike.

The assumption was that it was a simple PB contact.
Since it's apparently not, then we need to know exactly how that PB release works, and what it's power source does.

 

Did the electric door strike ever work?? Or is this a new installation?? If you hear the strike clicking but it does not release, either it is not getting enough voltage, or the mechanism is sticking. First, check the voltage at the power source to see if it drops much when the strike release button is pushed. Then check the voltage at the strike when it should operate. Voltage drops in the wiring are a classic cause of problems. The strike needs a lot more power than a doorbell, not everybody realizes that.

 

Update:

The Push Button Release from the front desk, I hear it clicking, so its trying to do something but no response from the Strike.

Probably designed to be connected to the door lock mechanism, not directly to the strike.
If not then that extra relay may be needed.

 

OK, so now we know both that the electric strike release works with that power source and we also know that the power source is capable. What remains that is not working is the segment from the front desk, both the actual push button device, and the wiring of the push button that is not common with the other wiring. We also know that the connection scheme seems to be correct because the strike makes a sound at the right tie. This implies that either the front desk push button is not adequate or that the wires unique to that push button are two thin. A momentary wire connection to bypass the " The Push Button Release from the front desk " and see if the release functions.

 

Morning Guys,

So when I hook up the Push Button Release to the Relay, it doesnt provide power to it. So I might have to reverse how its hooked up so something else can provide the power? Ideas?

 

If you would post a link to this Push Button Release I'm sure we can figure this out.

 

If there is no sound when the push button to operate the relay is pressed, it is quite likely that there is no power connection to that loop of the circuit. What I see in the wiring diagram in post #10 is the push button connected across the relay coil. There needs to be a connection to the power source inside that loop. ( Basic electricity class, second session, week one.)

The TS in post #7 said this:
"The Push Button Release from the front desk has its own individual power source not shown in the diagram."
Apparently it's not connected correctly and still waiting on a link or model # of said switch to verify.
I figure it's something like this:

OK but what about this push button switch?
There's an Unlock button on the Monitor is that being used?

 

That link in post #17 illustrates why I do not like amazon.

Correct, there is a push button at the front desk that is being used. That sends the signal through a data cable to the local conenction to release the door. Like I said, I can hear a click but it doesnt provide power to the lock or relay.

 

OK, now we haave a totally different explanation!! " That sends the signal through a data cable to the local connection". THAT is totally different than "completing the circuit to provide power to the door release."
Consider that if it IS completing the circuit to provide power, using a "data cable", which may be two conductors in a CAT5 cable or a CAT6 data cable might easily have enough resistance to not operate the release mechanism. THAT can be checked by measuring the voltage AT THE RELEASE MECHANISM when the button is pressed, and compare that measurement to the voltage when the card reader is used to operate the release.
