door access

[samson]

heya guys,

getting ready to build soon and one thing I would like to incorporate is HID/PROX access on exterior doors.

Can someone give me a quick "howto"

interested in what hardware to use - input and controller, wiring in between.

would like to control either door strikes or deadbolts with them

thanks for yer help

Slickest way I've found without adding another controller is to use an Elk panel and send 26 bit Weigand into the bus, either via a keypad or a door access station, then add the appropriate strikes, relays and power supplies for your application.

If you're unexperienced, with the application, plan on either a composite cable to the main panel or a 22/6, 22/4, 22/2, and an 18/2 is really what I'd call a minimum pull to each door location.

I was planning on using a elk panel for my security system, glass break/motion/contacts/etc..

so I can just use that eh, got a link to documentation or a howto?

thanks again

There's not really a quick "how to". Depending on your situation and what you plan on doing or monitoring at the door, there could be a few different ways to accomplish the same thing. You can wire a wiegand reader to some of the Elk keypads (check which ones) or you can use a Elk M1KAM access module. I recommend reading the elk manual and the appropriate manuals a few times before you begin planning and buying equipment.
DELInstallations gave you a good starting point for wiring, once again, your situation and cable pull may change depending on what you plan on doing at the door.

Also, the M1KAM will take the place of one keypad address in the system.

Be aware of the wiring distance for a reader from a M1KAM is limited to 50', and I'd assume similar or less for connecting a weigand input to a standard elk keypad. All reader wiring should be shielded.

Irregardless, you need to figure out if you're using a strike, electric lock or electrified handleset, then figure out how you're going to handle egress, since the lock should be a fail-secure item. If there's a button or REX PIR being used for egress, you need to have some sort of hardware to allow physical usage of the door in an emergency event. You'll also need to plan for the amount of material that would be removed for the installation of the locking hardware as well, since they're generally set for an ANSI door opening and typically on the deeper side.

I'd suggest to stay away from maglocks, too many issues to get involved with.

Then you'll have to plan the power requirements and voltage drop calculations for the lock power, in addition and I'd recommend separate from the alarm.
