I have Liftmaster LA500 automatic swing gate arm.
I have a pair of mag locks FAS-1300-gs
Need help in wiring the mag locks to power supply and gate arm.
Let me know if any diagram is needed.
 

Hi,

Is this the **broken link removed** for the FAS-1300GS?

Is this the right installation manual for the LA500?

How do you need help, please? Is it understanding the wiring, where to fit the mag locks, or another issue?

Page 32 shows the connections for the mag locks, page 1 of the other shows power and relay wiring.

Hi again,

Trying to read the LA500 installation manual, I'm a bit lost, so some-one else should confirm or negate the following:

I think, based on page 32, last bullet point - "Auxillary power - 24V DC", if either of the two options are usable for you, you can power the mag locks from those two DC supply points. I am not convinced about that being so at all.

The top of page 32 shows the mag lock option as though you need (...an AC/DC power supply???...) something whose definition I haven't located in the manual yet between the control board relay points and the mag lock(s), and it does say "not provided" in brackets. After a fair search I still can't tell, but am guessing the control board relay output could or couldn't be 120V/240V AC??

Perhaps auxillary power and the mag lock relay are both 24V DC, as they are next to each other on the board, but I can't be certain.

Sorry, Narinesa, unless another member understands this type of gate control board, I'd try to locate the LA500 technical department and enquire what "not provided" is, and suggest to them on my behalf that they remember to put the voltages and type (AC or DC) on the pictures of the control board, either page 53 or page 54, or in a humanly comprehensible table for the average consumer...

"Not provided" appears to be a wall plug adapter of some kind, or an accessory they or the mag lock manufacturer may sell.

Hi,

Ignore most of the above, summary is:

Do mag locks require a separate power supply and a control signal supply? - I am guessing so.

Trying to read the LA500 installation manual and the FAS one..., but don't take my word for any of this:

I think, based on page 32, last bullet point - "Auxillary power - 24V DC", if either of the two options are usable for you, you can power the mag locks from those two DC supply points. I am not convinced about that being so at all.

"Not provided" appears to be a wall plug adapter of some kind, in your case a 12 or 24V DC adapter/power supply.

I assume that the FAS yellow, blue, purple, brown need to be powered by a DC power supply with the pertinent wiring as shown in the manual: for 12V or 24V DC.

The "mag lock" wiring diagram on page 32, and pages 53 and 54 show that you need a separate wall-wart/supply for what I think is the mag lock control signal, as the FAS has red, black, white wires also? If so, then positive wire of wall-wart/DC supply goes to relay normally closed and the negative wire to the elongated mag lock part, and com is wired to the other half of the mag lock (I've never seen a mag lock before, but I guess from the picture you'll know which part is which).

I have separate external power adapter for 24v dc
LA500 cannot power any mag locks. There only the lock control connections will be used
I have two mag locks
The attached diagram for the mag locks connection does not look correct

Hi,

Do you mean that the external power adapter positive wire should be connected to the relay com, but isn't in the diagram, whereas the solenoid appears to be correctly drawn/wired?
 

I don't know if the external + power supply should be connected to COM or NC
The maglock connection in the diagram is to the left of the solenoid on the same circuit
I am looking for all the complete electrical connection
 

Here is a complete diagram

Hi,

What do mag locks do, Narinesa? I mean, are they only powered when locking? - I imagine so, but "imagine" is not good enough, frankly. To be honest, I'm beginning to feel uncomfortable guessing how that needs to be connected based on how it may or may not work, so if you don't mind, besides the following, I'd rather not suggest anything else in case I've failed to understand how that works, and I recommend using the contact page to check with what I hope is a member of the technical staff at FAS.

Com is the one that I had always thought provides the voltage to NO or NC, not the other way round, so I don't understand why it's not drawn like that in the manual, but it is for the solenoid.

Provisionally, I'd guess that, if the power supply is 500mA to 1A, if the mag locks operate at the same time, they both need to be connected to the same supply, and the same goes for the relay connections on the LA500.

What does this mean on the **broken link removed**: "Dual Voltage Current Draw - 500mA / 12V 250mA / 24V" - Two locks need a total of 250mA, or each lock needs 250mA at 24V? See what I mean... Sorry, but best get the right information from the horse's mouth, rather than a lot of questionable speculation, which is all I feel I am able to offer as answers, okay.
 

Maglock is a gate lock like a door lock but it is with an electric magnet/coil.
Dual voltage means that it can work with either 12v or 24v depending on the wiring.

I have 2 suggestions for review and comment - they are both different

Hi,

I'm probably wrong, in principle #2 looks okay, but I think I would swap the connections around and put +24V on the relay COM, both mag locks yellows on NC, and both mag locks browns on the power supply -V/0V connection. It is a 0V - 24V power supply (i.e. not -24V - +24V DC), isn't it?

I think there's possibly a human lapse of concentration error in #1: the yellow +24V is drawn connected to 0V/-V on the power supply, and the brown 0V/-V would be connected (via the relay) to the positive wire. Is there something I'm missing here about this kind of lock/coil?

So I can learn something - Is suggestion #1 a valid wiring method, or a postulation?
 

ok I have designed a diagram from research.
Just want to confirm if this is correct

Hi Narinesa,

Correct or not, I wouldn't like to place any bets on it either way, as I have already said I know nothing about mag locks.

My common sense tells me that I wouldn't try that, I can see no special reason for wiring the locks in series, and possibly a problem or two coming from doing so, I'd wire them in parallel, so both mag locks see 24V and 0V at the respective terminals; the last post schematic makes me think of lock 1 seeing 24V and no ground reference, and lock 2 seeing whatever voltage is left over from lock 1 and a ground reference, doesn't make much sense to me, but as I'm unfamiliar with mag locks I don't know if they can be wired in series or not and how (dys) functional that method may prove to be, even if both can work on 12V, if that's a valid method, like LEDs in series, why not?

Hi,

Just realised something, the wiring diagram shows both locks wired for 24V each in series with a 24V supply...that isn't going to work: 24V + 24V in series = 48V needed...

I was browsing a few mag lock installation and wiring manuals online, after "Googling" the search term: wiring two mag locks in series, I've yet to see one document or link that shows two wired in series, they were all in parallel, for what it's worth. This pdf may be interesting to look at, even if it's not for that make and model of lock, page 7 is what I mean/think, but without the diodes, and understanding that in essence an NC button can be considered to be the functional equivalent of the relay on the LA500 board.

Hope you get it to work.
