Caddx NX8E door electric strike

[jawdoc]

Hello
I have installed a Caddx NX8E in my office. Can I program a code to
activate an electric door strike or magnetic lock? If so do I have to
have an additional module ie relay module etc or can I do it with the
NX8E as is.
Thanks in advance!

NX8E as is.

The NX8-E has four programmable outputs on board the master control panel.
You can use one of them to trigger a low current relay which in turn
operates the door strike. Don't connect the aux outputs directly to the
door strike though. They're designed for low current loads. You can then
assign a user code to trigger the desired output for the door. There are a
few programming entries needed but it's not hard to set up.

ELK Products and Altronix both make low current relay boards which will do
what you need. There are other brands as well but I carry these in my
online store.

Thanks Robert
I have the manual. Do you know off the top of your head which
locations I have to program?
I will indeed get the relay board after I get it working.
Thanks

The NX-8E already has two 1-amp relay outputs

He doesn't need them but even if he did require external relays I'm suprised
you didn't mention Caddx's own nx507

 

[jawdoc]

OK, I got that working perfectly.
Now can I program the Caddx to bypass that zone temporarily during the
time that the relay is active(door is open and entry is allowed).

Mark... I'm surprised at you!! "1-amp" is considered "low current".
Depending on the door strike the OP is using you could easily draw more than
1 amp from your power supply.

suprised

ISTR he doesn't like Ademco's contacts at all and won't recommend their use
even though they're still featured on his website.

Yes. You'll have to wire the applicable zone through another of the onboard
relays that "follows" the first so that whenever you activate the strike the
panel sees a "normal" condition across the zone. You can program the second
(zone) relay to stay activated for a few seconds longer to allow you to
enter the door at a more liesurely pace.

What's the current draw on your door strike?? If it's less than 1 amp, you
may be able to wire it directly to one of the NX-8 relays.

 

[jawdoc]

Thanks Frank
My strike is less than 1 amp and I have that going fine.
I do understand the second zone relay however if I put an EOL resistor
across the second relay to simulate a normal condition will it not
trigger the alarm during the transition? I have not tried that yet.
Thanks again for your time!

That's true. I usually reserve on-board relays for sirens, strobes, etc.,
so I didn't copnsider using them for this purpose but you're right, they
could be used.

He doesn't need them but even if he did require
external relays I'm suprised you didn't mention
Caddx's own nx507

The NX-507 is discontinued. It's been replaced by the NX-507E. I didn't
suggest either of these because they cost several times as much as ELK's and
Altronix' relay boards. If one of the on-board relays is available that's
fine. If not, ELK or Altronix are preferable IMO to the Caddx module.

That's not a built-in function but you could use a simple timer to do the
job for you.

It shouldn't be a problem as long as you "break" the connection to the field
resistor at the same time you're "making" the connection to the one you've
got in the control. It will require using both sides of the relay (N.O. and
N. C.). You can set the zone's reaction time to a fault condition for
slightly longer than the default if you have to.

 

[Robert L. Bass]

He did not mention sirens or strobes he just said door strikes

I'm not disagreeing with you -- only saying how I would have done it.

The Caddx module will be supervised by the panel whereas the Elk or
Altronix
will not be

An *unsupervised* relay sitting inside the control panel. How dangerous.

And no reason for it either

I solved my problem by purchasing a door access controller that had an
alarm shunt on it.
I still use my Caddx to allow entry, also I have it so that the
magnetic lock is only active during the armed state. I programmed a
code to allow quick in and out entry "after hours" without disarming
the alarm and maintaining the magnetic lock(alarm shunt on access
controller).
Thanks for all the help.
